 	"title": "HTTP Adapter",

 	"description": "",
-	"content": "The HTTP protocol adapter exposes HTTP based endpoints for Eclipse Hono\u0026trade;\u0026rsquo;s south bound Telemetry, Event and Command \u0026amp; Control APIs.\nDevice Authentication The HTTP adapter by default requires clients (devices or gateway components) to authenticate during connection establishment. The adapter supports both the Basic HTTP authentication scheme as well as client certificate based authentication as part of a TLS handshake for that purpose.\nThe adapter tries to authenticate the device using these mechanisms in the following order\nClient Certificate When a device uses a client certificate for authentication during the TLS handshake, the adapter tries to determine the tenant that the device belongs to, based on the issuer DN contained in the certificate. In order for the lookup to succeed, the tenant\u0026rsquo;s trust anchor needs to be configured by means of registering the trusted certificate authority. The device\u0026rsquo;s client certificate will then be validated using the registered trust anchor, thus implicitly establishing the tenant that the device belongs to. In a second step, the adapter then uses the Credentials API\u0026rsquo;s get operation with the client certificate\u0026rsquo;s subject DN as the auth-id and x509-cert as the type of secret as query parameters.\nNB: The HTTP adapter needs to be configured for TLS in order to support this mechanism.\nHTTP Basic Auth The username provided in the header must have the form auth-id@tenant, e.g. sensor1@DEFAULT_TENANT. The adapter verifies the credentials provided by the client against the credentials that the configured Credentials service has on record for the client. The adapter uses the Credentials API\u0026rsquo;s get operation to retrieve the credentials on record with the tenant and auth-id provided by the device in the username and hashed-password as the type of secret as query parameters.\nThe examples below refer to devices 4711 and gw-1 of tenant DEFAULT_TENANT using auth-ids sensor1 and gw1 and corresponding passwords. The example deployment as described in the Deployment Guides comes pre-configured with the corresponding entities in its device registry component. Please refer to the Credentials API for details regarding the different types of secrets.\nNB There is a subtle difference between the device identifier (device-id) and the auth-id a device uses for authentication. See Device Identity for a discussion of the concepts.\nMessage Limits Before accepting any telemetry or event or command messages, the HTTP adapter verifies that the configured message limit is not exceeded. If the limit is exceeded then the incoming message is discarded with the status code 429 Too Many Requests.\nPublish Telemetry Data (authenticated Device)  URI: /telemetry Method: POST Request Headers:  (optional) authorization: The device\u0026rsquo;s auth-id and plain text password encoded according to the Basic HTTP authentication scheme. If not set, the adapter expects the device to present a client certificate as part of the TLS handshake during connection establishment. (required) content-type: The type of payload contained in the request body. (optional) hono-ttd: The number of seconds the device will wait for the response. (optional) qos-level: The QoS level for publishing telemetry messages. The adapter supports at most once (0) and at least once (1) QoS levels. The default value of 0 is assumed if this header is omitted.  Request Body:  (required) Arbitrary payload encoded according to the given content type.  Response Headers:  (optional) content-type: A media type describing the semantics and format of payload contained in the response body. This header will only be present if the response contains a command to be executed by the device which requires input data. (optional) hono-command: The name of the command to execute. This header will only be present if the response contains a command to be executed by the device. (optional) hono-cmd-req-id: An identifier that the device must include in its response to a command. This header will only be present if the response contains a command to be executed by the device.  Response Body:  (optional) Arbitrary data serving as input to a command to be executed by the device, if status code is 200. (optional) Error details, if status code is \u0026gt;= 400.  Status Codes:  200 (OK): The telemetry data has been accepted for processing. The response contains a command for the device to execute. 202 (Accepted): The telemetry data has been accepted for processing. Note that if the qos-level request header is omitted (at most once semantics), this status code does not mean that the message has been delivered to any potential consumer. However, if the QoS level header is set to 1 (at least once semantics), then the adapter waits for the message to be delivered and accepted by a downstream consumer before responding with this status code. 400 (Bad Request): The request cannot be processed. Possible reasons for this include:  The content type header is missing. The request body is empty. The QoS header value is invalid.  401 (Unauthorized): The request cannot be processed because the request does not contain valid credentials. 403 (Forbidden): The request cannot be processed because the device\u0026rsquo;s registration status cannot be asserted. Possible reasons for this include:  The given tenant is not allowed to use this protocol adapter.  404 (Not Found): The request cannot be processed because the device is disabled or does not exist. 429 (Too Many Requests): The request cannot be processed because the tenant\u0026rsquo;s message limit for the current period is exceeded. 503 (Service Unavailable): The request cannot be processed because there is no consumer of telemetry data for the given tenant connected to Hono.   This is the preferred way for devices to publish telemetry data. It is available only if the protocol adapter is configured to require devices to authenticate (which is the default).\nExamples\nPublish some JSON data for device 4711:\ncurl -i -u sensor1@DEFAULT_TENANT:hono-secret -H 'content-type: application/json' --data-binary '{\u0026quot;temp\u0026quot;: 5}' http://127.0.0.1:8080/telemetry HTTP/1.1 202 Accepted content-length: 0  Publish some JSON data for device 4711 using at least once QoS:\ncurl -i -u sensor1@DEFAULT_TENANT:hono-secret -H 'content-type: application/json' -H 'QoS-Level: 1' --data-binary '{\u0026quot;temp\u0026quot;: 5}' http://localhost:8080/telemetry HTTP/1.1 202 Accepted content-length: 0  Publish some JSON data for device 4711, indicating that the device will wait for 10 seconds to receive the response:\ncurl -i -u sensor1@DEFAULT_TENANT:hono-secret -H 'content-type: application/json' -H 'hono-ttd: 10' --data-binary '{\u0026quot;temp\u0026quot;: 5}' http://localhost:8080/telemetry HTTP/1.1 200 OK hono-command: set hono-cmd-req-id: 1010a7249aa5-f742-4376-8458-bbfc88c72d92 content-length: 23 { \u0026quot;brightness\u0026quot; : 87 }  Publish some JSON data for device 4711 using a client certificate for authentication:\n# in base directory of Hono repository: curl -i --cert demo-certs/certs/device-4711-cert.pem --key demo-certs/certs/device-4711-key.pem --cacert demo-certs/certs/trusted-certs.pem -H 'content-type: application/json' --data-binary '{\u0026quot;temp\u0026quot;: 5}' https://localhost:8443/telemetry HTTP/1.1 202 Accepted content-length: 0  NB: The example above assumes that the HTTP adapter is configured for TLS and the secure port is used.\nPublish Telemetry Data (unauthenticated Device)  URI: /telemetry/${tenantId}/${deviceId} Method: PUT Request Headers:  (required) content-type: The type of payload contained in the body.

Note that if the qos-level request header is omitted (at most once semantics), this status code does not mean that the message has been delivered to any potential consumer. However, if the QoS level header is set to 1 (at least once semantics), then the adapter waits for the message to be delivered and accepted by a downstream consumer before responding with this status code. 400 (Bad Request): The request cannot be processed. Possible reasons for this include:  The content type header is missing. The request body is empty. The QoS header value is invalid.  401 (Unauthorized): The request cannot be processed because the request does not contain valid credentials. 403 (Forbidden): The request cannot be processed because the device\u0026rsquo;s registration status cannot be asserted. Possible reasons for this include:  The tenant that the gateway belongs to is not allowed to use this protocol adapter. The device belongs to another tenant than the gateway. The gateway is not authorized to act on behalf of the device. The gateway associated with the device is not registered or disabled.  404 (Not Found): The request cannot be processed because the device is disabled or does not exist. 429 (Too Many Requests): The request cannot be processed because the tenant\u0026rsquo;s message limit for the current period is exceeded. 503 (Service Unavailable): The request cannot be processed because there is no consumer of telemetry data for the given tenant connected to Hono.

The HTTP adapter\u0026rsquo;s type name is hono-http.   orig_address string Contains the (relative) URI that the device has originally posted the data to.   ttd integer Contains the effective number of seconds that the device will wait for a response. This property is only set if the HTTP request contains the hono-ttd header or request parameter.    The adapter also considers defaults registered for the device at either the tenant or the device level. The values of the default properties are determined as follows:\n If the message already contains a non-empty property of the same name, the value if unchanged. Otherwise, if a default property of the same name is defined in the device\u0026rsquo;s registration information, that value is used. Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.  Note that of the standard AMQP 1.0 message properties only the content-type and ttl can be set this way to a default value.\nEvent Message Time-to-live Events published by devices will usually be persisted by the AMQP Messaging Network in order to support deferred delivery to downstream consumers. In most cases the AMQP Messaging Network can be configured with a maximum time-to-live to apply to the events so that the events will be removed from the persistent store if no consumer has attached to receive the event before the message expires.\nIn order to support environments where the AMQP Messaging Network cannot be configured accordingly, the protocol adapter supports setting a downstream event message\u0026rsquo;s ttl property based on the default ttl and max-ttl values configured for a tenant/device as described in the Tenant API.\nTenant specific Configuration The adapter uses the Tenant API to retrieve tenant specific configuration for adapter type hono-http. The following properties are (currently) supported:\n   Name Type Default Value Description     enabled boolean true If set to false the adapter will reject all data from devices belonging to the tenant.   max-ttd integer 60 Defines a tenant specific upper limit for the time until disconnect property that devices may include in requests for uploading telemetry data or events. Please refer to the Command \u0026amp; Control concept page for a discussion of this parameter\u0026rsquo;s purpose and usage.\nIf this property is not set for the hono-http adapter type, the adapter will try to read this property from the tenant level configuration.

+	"content": "The HTTP protocol adapter exposes HTTP based endpoints for Eclipse Hono\u0026trade;\u0026rsquo;s south bound Telemetry, Event and Command \u0026amp; Control APIs.\nDevice Authentication The HTTP adapter by default requires clients (devices or gateway components) to authenticate during connection establishment. The adapter supports both the Basic HTTP authentication scheme as well as client certificate based authentication as part of a TLS handshake for that purpose.\nThe adapter tries to authenticate the device using these mechanisms in the following order\nClient Certificate When a device uses a client certificate for authentication during the TLS handshake, the adapter tries to determine the tenant that the device belongs to, based on the issuer DN contained in the certificate. In order for the lookup to succeed, the tenant\u0026rsquo;s trust anchor needs to be configured by means of registering the trusted certificate authority. The device\u0026rsquo;s client certificate will then be validated using the registered trust anchor, thus implicitly establishing the tenant that the device belongs to. In a second step, the adapter then uses the Credentials API\u0026rsquo;s get operation with the client certificate\u0026rsquo;s subject DN as the auth-id and x509-cert as the type of secret as query parameters.\nNB: The HTTP adapter needs to be configured for TLS in order to support this mechanism.\nHTTP Basic Auth The username provided in the header must have the form auth-id@tenant, e.g. sensor1@DEFAULT_TENANT. The adapter verifies the credentials provided by the client against the credentials that the configured Credentials service has on record for the client. The adapter uses the Credentials API\u0026rsquo;s get operation to retrieve the credentials on record with the tenant and auth-id provided by the device in the username and hashed-password as the type of secret as query parameters.\nThe examples below refer to devices 4711 and gw-1 of tenant DEFAULT_TENANT using auth-ids sensor1 and gw1 and corresponding passwords. The example deployment as described in the Deployment Guides comes pre-configured with the corresponding entities in its device registry component. Please refer to the Credentials API for details regarding the different types of secrets.\nNB There is a subtle difference between the device identifier (device-id) and the auth-id a device uses for authentication. See Device Identity for a discussion of the concepts.\nMessage Limits Before accepting any telemetry or event or command messages, the HTTP adapter verifies that the configured message limit is not exceeded. If the limit is exceeded then the incoming message is discarded with the status code 429 Too Many Requests.\nPublish Telemetry Data (authenticated Device)  URI: /telemetry Method: POST Request Headers:  (optional) authorization: The device\u0026rsquo;s auth-id and plain text password encoded according to the Basic HTTP authentication scheme. If not set, the adapter expects the device to present a client certificate as part of the TLS handshake during connection establishment. (required) content-type: The type of payload contained in the request body. (optional) hono-ttd: The number of seconds the device will wait for the response. (optional) qos-level: The QoS level for publishing telemetry messages. The adapter supports at most once (0) and at least once (1) QoS levels. The default value of 0 is assumed if this header is omitted.  Request Body:  (required) Arbitrary payload encoded according to the given content type.

The response contains a command for the device to execute. 202 (Accepted): The telemetry data has been accepted for processing. Note that if the qos-level request header is omitted (at most once semantics), this status code does not mean that the message has been delivered to any potential consumer. However, if the QoS level header is set to 1 (at least once semantics), then the adapter waits for the message to be delivered and accepted by a downstream consumer before responding with this status code. 400 (Bad Request): The request cannot be processed.

Examples\nSend a response to a previously received command with the command-request-id req-id-uuid for device 4712:\ncurl -i -X PUT -u gw@DEFAULT_TENANT:gw-secret -H 'content-type: application/json' --data-binary '{\u0026quot;brightness-changed\u0026quot;: true}' http://127.0.0.1:8080/command/res/DEFAULT_TENANT/4712/req-id-uuid?hono-cmd-status=200 HTTP/1.1 202 Accepted content-length: 0  NB: The example above assumes that a gateway device has been registered with hashed-password credentials with auth-id gw and password gw-secret which is authorized to publish data on behalf of device 4712.\nDownstream Meta Data The adapter includes the following meta data in the application properties of messages being sent downstream:\n   Name Type Description     device_id string The identifier of the device that the message originates from.   orig_adapter string Contains the adapter\u0026rsquo;s type name which can be used by downstream consumers to determine the protocol adapter that the message has been received over. The HTTP adapter\u0026rsquo;s type name is hono-http.   orig_address string Contains the (relative) URI that the device has originally posted the data to.   ttd integer Contains the effective number of seconds that the device will wait for a response. This property is only set if the HTTP request contains the hono-ttd header or request parameter.    The adapter also considers defaults registered for the device at either the tenant or the device level. The values of the default properties are determined as follows:\n If the message already contains a non-empty property of the same name, the value if unchanged. Otherwise, if a default property of the same name is defined in the device\u0026rsquo;s registration information, that value is used. Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.  Note that of the standard AMQP 1.0 message properties only the content-type and ttl can be set this way to a default value.\nEvent Message Time-to-live Events published by devices will usually be persisted by the AMQP Messaging Network in order to support deferred delivery to downstream consumers. In most cases the AMQP Messaging Network can be configured with a maximum time-to-live to apply to the events so that the events will be removed from the persistent store if no consumer has attached to receive the event before the message expires.\nIn order to support environments where the AMQP Messaging Network cannot be configured accordingly, the protocol adapter supports setting a downstream event message\u0026rsquo;s ttl property based on the hono-ttl property set as a header or a query parameter in the event requests by the devices. Also the default ttl and max-ttl values can be configured for a tenant/device as described in the Tenant API.\nTenant specific Configuration The adapter uses the Tenant API to retrieve tenant specific configuration for adapter type hono-http. The following properties are (currently) supported:\n   Name Type Default Value Description     enabled boolean true If set to false the adapter will reject all data from devices belonging to the tenant.   max-ttd integer 60 Defines a tenant specific upper limit for the time until disconnect property that devices may include in requests for uploading telemetry data or events. Please refer to the Command \u0026amp; Control concept page for a discussion of this parameter\u0026rsquo;s purpose and usage.\nIf this property is not set for the hono-http adapter type, the adapter will try to read this property from the tenant level configuration.

-	"content": "The MQTT protocol adapter exposes an MQTT topic hierarchy for publishing telemetry data and events to downstream consumers and for receiving commands from applications and sending back responses.\nThe MQTT adapter is not a general purpose MQTT broker. In particular the adapter\n supports MQTT 3.1.1 only. does not maintain session state for clients and thus always sets the session present flag in its CONNACK packet to 0, regardless of the value of the clean session flag provided in a client\u0026rsquo;s CONNECT packet. ignores any Will included in a client\u0026rsquo;s CONNECT packet. only supports topic names/filters for devices to publish and subscribe to that are specific to Hono\u0026rsquo;s functionality as described in the following sections. does not support retaining messages. However, if an event or telemetry message\u0026rsquo;s retain flag is set to 1 then the corresponding AMQP 1.0 message being sent downstream by the adapter will contain an x-opt-retain message annotation containing the boolean value true. A downstream consumer may then react according to the presence of this annotation.  Authentication The MQTT adapter by default requires clients (devices or gateway components) to authenticate during connection establishment. The adapter supports both the authentication based on the username/password provided in an MQTT CONNECT packet as well as client certificate based authentication as part of a TLS handshake for that purpose.\nThe adapter tries to authenticate the device using these mechanisms in the following order\nClient Certificate When a device uses a client certificate for authentication during the TLS handshake, the adapter tries to determine the tenant that the device belongs to, based on the issuer DN contained in the certificate. In order for the lookup to succeed, the tenant\u0026rsquo;s trust anchor needs to be configured by means of registering the trusted certificate authority. The device\u0026rsquo;s client certificate will then be validated using the registered trust anchor, thus implicitly establishing the tenant that the device belongs to. In a second step, the adapter then uses the Credentials API\u0026rsquo;s get operation with the client certificate\u0026rsquo;s subject DN as the auth-id and x509-cert as the type of secret as query parameters.\nNB The adapter needs to be configured for TLS in order to support this mechanism.\nUsername/Password When a device wants to authenticate using this mechanism, it needs to provide a username and a password in the MQTT CONNECT packet it sends in order to initiate the connection. The username must have the form auth-id@tenant, e.g. sensor1@DEFAULT_TENANT. The adapter verifies the credentials provided by the client against the credentials the configured Credentials service has on record for the client. The adapter uses the Credentials API\u0026rsquo;s get operation to retrieve the credentials on record with the tenant and auth-id provided by the client in the username and hashed-password as the type of secret as query parameters.\nThe examples below refer to devices 4711 and gw-1 of tenant DEFAULT_TENANT using auth-ids sensor1 and gw1 and corresponding passwords. The example deployment as described in the Deployment Guides comes pre-configured with the corresponding entities in its device registry component.\nNB There is a subtle difference between the device identifier (device-id) and the auth-id a device uses for authentication. See Device Identity for a discussion of the concepts.\nConnection Limits After verifying the credentials, the number of existing connections is checked against the configured resource-limits by the MQTT adapter. If the limit is exceeded then a return code 0x05 indicating Connection Refused: not authorised is sent back.\nMessage Limits Before accepting any telemetry or event or command messages, the MQTT adapter verifies that the configured message limit is not exceeded. The incoming message is discarded if the limit is exceeded.\nPublishing Telemetry Data The MQTT adapter supports the publishing of telemetry data by means of MQTT PUBLISH packets using either QoS 0 or QoS 1. Using QoS 1 will result in the adapter sending an MQTT PUBACK packet to the client once the message has been settled with the accepted outcome by the AMQP 1.0 Messaging Network.\nThis requires that\n the AMQP 1.0 Messaging Network has capacity to process telemetry messages for the client\u0026rsquo;s tenant and the messages published by the client comply with the format defined by the Telemetry API.  The protocol adapter checks the configured message limit before accepting any telemetry messages. If the message limit is exceeded or the incoming telemetry message cannot be processed, the connection to the client is closed.\nPublish Telemetry Data (authenticated Device)  Topic: telemetry or t Authentication: required Payload:  (required) Arbitrary payload   This is the preferred way for devices to publish telemetry data. It is available only if the protocol adapter is configured to require devices to authenticate (which is the default). When using this topic, the MQTT adapter determines the device\u0026rsquo;s tenant and device identity as part of the authentication process.\nExample\nPublish some JSON data for device 4711:\nmosquitto_pub -u 'sensor1@DEFAULT_TENANT' -P hono-secret -t telemetry -m '{\u0026quot;temp\u0026quot;: 5}'  Publish some JSON data for device 4711 using a client certificate for authentication:\n# in base directory of Hono repository: mosquitto_pub -p 8883 -t telemetry -m '{\u0026quot;temp\u0026quot;: 5}' --cert demo-certs/certs/device-4711-cert.pem --key demo-certs/certs/device-4711-key.pem --cafile demo-certs/certs/trusted-certs.pem  NB: The example above assumes that the MQTT adapter is configured for TLS and the secure port is used.\nPublish Telemetry Data (unauthenticated Device)  Topic: telemetry/${tenant-id}/${device-id} or t/${tenant-id}/${device-id} Authentication: none Payload:  (required) Arbitrary payload   This topic can be used by devices that have not authenticated to the protocol adapter. Note that this requires the HONO_MQTT_AUTHENTICATION_REQUIRED configuration property to be explicitly set to false.\nExamples\nPublish some JSON data for device 4711:\nmosquitto_pub -t telemetry/DEFAULT_TENANT/4711 -m '{\u0026quot;temp\u0026quot;: 5}'  Publish Telemetry Data (authenticated Gateway)  Topic: telemetry/${tenant-id}/${device-id} or t/${tenant-id}/${device-id} Authentication: required Payload:  (required) Arbitrary payload   This topic can be used by gateway components to publish data on behalf of other devices which do not connect to a protocol adapter directly but instead are connected to the gateway, e.g. using some low-bandwidth radio based technology like SigFox or LoRa. In this case the credentials provided by the gateway during connection establishment with the protocol adapter are used to authenticate the gateway whereas the parameters from the topic name are used to identify the device that the gateway publishes data for.\nThe protocol adapter checks the gateway\u0026rsquo;s authority to publish data on behalf of the device implicitly by means of retrieving a registration assertion for the device from the configured Device Registration service.\nExamples\nPublish some JSON data for device 4712 via gateway gw-1:\nmosquitto_pub -u 'gw@DEFAULT_TENANT' -P gw-secret -t telemetry/DEFAULT_TENANT/4712 -m '{\u0026quot;temp\u0026quot;: 5}'  NB: The example above assumes that a gateway device with ID gw-1 has been registered with hashed-password credentials with auth-id gw and password gw-secret.\nPublishing Events The MQTT adapter supports the publishing of events by means of MQTT PUBLISH packets using QoS 1 only. The adapter will send an MQTT PUBACK packet to the client once the event has been settled with the accepted outcome by the AMQP 1.0 Messaging Network.\nThis requires that\n the AMQP 1.0 Messaging Network has capacity to process events for the client\u0026rsquo;s tenant and the events published by the client comply with the format defined by the Event API.  The protocol adapter checks the configured message limit before accepting any event messages. If the message limit is exceeded or the incoming event message cannot be processed, the connection to the client is closed.\nPublish an Event (authenticated Device)  Topic: event or e Authentication: required Payload:  (required) Arbitrary payload   This is the preferred way for devices to publish events. It is available only if the protocol adapter has been configured to require devices to authenticate (which is the default).\nExample\nUpload a JSON string for device 4711:\nmosquitto_pub -u 'sensor1@DEFAULT_TENANT' -P hono-secret -t event -q 1 -m '{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (unauthenticated Device)  Topic: event/${tenant-id}/${device-id} or e/${tenant-id}/${device-id} Authentication: none Payload:  (required) Arbitrary payload   This topic can be used by devices that have not authenticated to the protocol adapter. Note that this requires the HONO_MQTT_AUTHENTICATION_REQUIRED configuration property to be explicitly set to false.\nExamples\nPublish some JSON data for device 4711:\nmosquitto_pub -t event/DEFAULT_TENANT/4711 -q 1 -m '{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (authenticated Gateway)  Topic: event/${tenant-id}/${device-id} or e/${tenant-id}/${device-id} Authentication: required Payload:  (required) Arbitrary payload   This topic can be used by gateway components to publish data on behalf of other devices which do not connect to a protocol adapter directly but instead are connected to the gateway, e.g. using some low-bandwidth radio based technology like SigFox or LoRa. In this case the credentials provided by the gateway during connection establishment with the protocol adapter are used to authenticate the gateway whereas the parameters from the topic name are used to identify the device that the gateway publishes data for.\nThe protocol adapter checks the gateway\u0026rsquo;s authority to publish data on behalf of the device implicitly by means of retrieving a registration assertion for the device from the configured Device Registration service.\nExamples\nPublish some JSON data for device 4712 via gateway gw-1:\nmosquitto_pub -u 'gw@DEFAULT_TENANT' -P gw-secret -t event/DEFAULT_TENANT/4712 -q 1 -m '{\u0026quot;temp\u0026quot;: 5}'  NB: The example above assumes that a gateway device with ID gw-1 has been registered with hashed-password credentials with auth-id gw and password gw-secret.\nCommand \u0026amp; Control The MQTT adapter supports devices to receive commands that have been sent by business applications by means of sending an MQTT SUBSCRIBE packet containing a device specific topic filter as described below. Devices can subscribe with QoS 1 or QoS 0. The adapter indicates the outcome of the subscription request by sending back a corresponding SUBACK packet. The SUBACK packet will contain Success - QoS 0 (0x00) or Success - QoS 1 (0x01) for a command topic filter indicating QoS 0 or 1 and will contain the Failure (0x80) value for all other filters. When a device no longer wants to receive commands anymore, it can send an MQTT UNSUBSCRIBE packet to the adapter, including the same topic filter that has been used to subscribe.\nWhen a device has successfully subscribed, the adapter sends an empty notification on behalf of the device to the downstream AMQP 1.0 Messaging Network with the ttd header set to -1, indicating that the device will be ready to receive commands until further notice. Analogously, the adapter sends an empty notification with the ttd header set to 0 when a device unsubscribes from commands.\nCommands can be sent following a request/response pattern or being one-way.\nFor Request/Response commands, devices send their responses to commands by means of sending an MQTT PUBLISH message to a topic that is specific to the command that has been executed. The MQTT adapter accepts responses being published using either QoS 0 or QoS 1.\nThe MQTT adapter checks the configured message limit before accepting any command requests and responses. In case of incoming command requests from business applications, if the message limit is exceeded, the Adapter rejects the message with the reason amqp:resource-limit-exceeded. And for the incoming command responses from devices, the Adapter rejects the message and closes the connection to the client.\nThe following sections define the topic filters/names to use for subscribing to and responding to commands. The following shorthand versions of topic path segments are supported:\n c instead of command q instead of req s instead of res   Note Previous versions of Hono used control instead of command as topic prefix. Using the control prefix is still supported but deprecated.  The following variables are used:\n ${command} : is an arbitrary string that indicates the command to execute, e.g. setBrightness. The command is provided by the application that sends the command. ${req-id} (only for Request/Response commands) : denotes the unique identifier of the command execution request and is passed to the device as part of the name of the topic that the command is published to. The device needs to publish its response to the command to a topic which includes this identifier, thus allowing the adapter to correlate the response with the request. ${status} : is the HTTP status code indicating the outcome of executing the command. This status code is passed on to the application in the AMQP message\u0026rsquo;s status header.  The property-bag is an optional collection of properties intended for the receiver of the message. A property bag is only allowed at the very end of a topic. It always starts with a ? character, followed by pairs of URL encoded property names and values that are separated by \u0026amp;. The following example shows a property bag that contains two properties seqNo and importance:\n/topic/name/?seqNo=10034\u0026amp;importance=\u0026quot;high\u0026quot;  The MQTT adapter currently does not require nor use any properties.\nReceiving Commands (authenticated Device) An authenticated device MUST use the following topic filter to subscribe to commands:\n command/+/+/req/#  Example\nmosquitto_sub -v -u 'sensor1@DEFAULT_TENANT' -P hono-secret -t command/+/+/req/#  The adapter will then publish commands for the device to topic:\n for Request/Response commands: command///req/${req-id}/${command} for one-way commands: command///req//${command}  Example\nFor example, if the HonoExampleApplication was started, after the ttd event requested by the subscription of mosquitto_sub, it layers a command that arrives as follows:\ncommand///q/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/setBrightness { \u0026quot;brightness\u0026quot; : 79 }  If the command is a one-way command, it will arrive as follows:\ncommand///q//setBrightness { \u0026quot;brightness\u0026quot; : 79 }  Receiving Commands (unauthenticated Device) An unauthenticated device MUST use the following topic filter to subscribe to commands:\n command/${tenant-id}/${device-id}/req/#  Example\nmosquitto_sub -v -t command/DEFAULT_TENANT/4711/req/#  The adapter will then publish Request/Response commands for the device to topic:\n command/${tenant-id}/${device-id}/req/${req-id}/${command}  and one-way commands to the topic:\n command/${tenant-id}/${device-id}/req//${command}  (For an example of the incoming command see above at authenticated device)\nReceiving Commands (authenticated Gateway) Gateway components can receive commands for devices which do not connect to a protocol adapter directly but instead are connected to the gateway, e.g. using some low-bandwidth radio based technology like SigFox or LoRa. Corresponding devices have to be configured so that they can be used with a gateway. See Configuring Gateway Devices for details.\nIf a device is configured in such a way that there can be one gateway, acting on behalf of the device, a command sent to this device will by default be directed to that gateway.\nIf a device is configured to be used with multiple gateways, the particular gateway that last acted on behalf of the device will be the target that commands for that device will be routed to. The mapping of device and gateway last used by the device is updated whenever a device sends a telemetry, event or command response message via the gateway. This means that for a device configured to be used via multiple gateways to receive commands, the device first has to send at least one telemetry or event message to establish which gateway to use for receiving commands for that device.\nAn authenticated gateway MUST use the following topic filter to subscribe to to commands for all the devices it acts on behalf of:\n command/+/+/req/#  Example\nmosquitto_sub -v -u 'gw@DEFAULT_TENANT' -P gw-secret -t command/+/+/req/#  The adapter will then publish commands for devices, that the gateway has acted on behalf of, to topic:\n for Request/Response commands: command//${device-id}/req/${req-id}/${command} for one-way commands: command//${device-id}/req//${command}  Sending a Response to a Command (authenticated Device) An authenticated device MUST send the response to a previously received command to the following topic:\n command///res/${req-id}/${status}  Example\nAfter a command has arrived as in the above example, you send a response using the arrived ${req-id}:\nmosquitto_pub -u 'sensor1@DEFAULT_TENANT' -P hono-secret -t command///res/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/200 -m '{\u0026quot;lumen\u0026quot;: 200}'  Sending a Response to a Command (unauthenticated Device) An unauthenticated device MUST send the response to a previously received command to the following topic:\n command/${tenant-id}/${device-id}/res/${req-id}/${status}  Example\nAfter a command has arrived as in the above example, you send a response using the arrived ${req-id}:\nmosquitto_pub -t command/DEFAULT_TENANT/4711/res/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/200 -m '{\u0026quot;lumen\u0026quot;: 200}'  Sending a Response to a Command (authenticated Gateway) An authenticated gateway MUST send the response to a previously received command to the following topic:\n command///res/${req-id}/${status}  Example\nAfter a command has arrived as in the above example, you send a response using the arrived ${req-id}:\nmosquitto_pub -u 'gw@DEFAULT_TENANT' -P gw-secret -t command///res/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/200 -m '{\u0026quot;lumen\u0026quot;: 200}'  Downstream Meta Data The adapter includes the following meta data in messages being sent downstream:\n   Name Location Type Description     device_id application string The identifier of the device that the message originates from.   orig_adapter application string Contains the adapter\u0026rsquo;s type name which can be used by downstream consumers to determine the protocol adapter that the message has been received over. The MQTT adapter\u0026rsquo;s type name is hono-mqtt.   orig_address application string Contains the name of the MQTT topic that the device has originally published the data to.   x-opt-retain * message-annotations boolean Contains true if the device has published an event or telemetry message with its retain flag set to 1    The adapter also considers defaults registered for the device at either the tenant or the device level. The values of the default properties are determined as follows:\n If the message already contains a non-empty property of the same name, the value if unchanged. Otherwise, if a default property of the same name is defined in the device\u0026rsquo;s registration information, that value is used. Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.  Note that of the standard AMQP 1.0 message properties only the content-type and ttl can be set this way to a default value.\nEvent Message Time-to-live Events published by devices will usually be persisted by the AMQP Messaging Network in order to support deferred delivery to downstream consumers.

It is available only if the protocol adapter has been configured to require devices to authenticate (which is the default).\nExample\nUpload a JSON string for device 4711:\nmosquitto_pub -u 'sensor1@DEFAULT_TENANT' -P hono-secret -t event -q 1 -m '{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (unauthenticated Device)  Topic: event/${tenant-id}/${device-id} or e/${tenant-id}/${device-id} Authentication: none Payload:  (required) Arbitrary payload   This topic can be used by devices that have not authenticated to the protocol adapter. Note that this requires the HONO_MQTT_AUTHENTICATION_REQUIRED configuration property to be explicitly set to false.\nExamples\nPublish some JSON data for device 4711:\nmosquitto_pub -t event/DEFAULT_TENANT/4711 -q 1 -m '{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (authenticated Gateway)  Topic: event/${tenant-id}/${device-id} or e/${tenant-id}/${device-id} Authentication: required Payload:  (required) Arbitrary payload   This topic can be used by gateway components to publish data on behalf of other devices which do not connect to a protocol adapter directly but instead are connected to the gateway, e.g. using some low-bandwidth radio based technology like SigFox or LoRa. In this case the credentials provided by the gateway during connection establishment with the protocol adapter are used to authenticate the gateway whereas the parameters from the topic name are used to identify the device that the gateway publishes data for.\nThe protocol adapter checks the gateway\u0026rsquo;s authority to publish data on behalf of the device implicitly by means of retrieving a registration assertion for the device from the configured Device Registration service.\nExamples\nPublish some JSON data for device 4712 via gateway gw-1:\nmosquitto_pub -u 'gw@DEFAULT_TENANT' -P gw-secret -t event/DEFAULT_TENANT/4712 -q 1 -m '{\u0026quot;temp\u0026quot;: 5}'  NB: The example above assumes that a gateway device with ID gw-1 has been registered with hashed-password credentials with auth-id gw and password gw-secret.\nCommand \u0026amp; Control The MQTT adapter supports devices to receive commands that have been sent by business applications by means of sending an MQTT SUBSCRIBE packet containing a device specific topic filter as described below. Devices can subscribe with QoS 1 or QoS 0. The adapter indicates the outcome of the subscription request by sending back a corresponding SUBACK packet. The SUBACK packet will contain Success - QoS 0 (0x00) or Success - QoS 1 (0x01) for a command topic filter indicating QoS 0 or 1 and will contain the Failure (0x80) value for all other filters. When a device no longer wants to receive commands anymore, it can send an MQTT UNSUBSCRIBE packet to the adapter, including the same topic filter that has been used to subscribe.\nWhen a device has successfully subscribed, the adapter sends an empty notification on behalf of the device to the downstream AMQP 1.0 Messaging Network with the ttd header set to -1, indicating that the device will be ready to receive commands until further notice. Analogously, the adapter sends an empty notification with the ttd header set to 0 when a device unsubscribes from commands.\nCommands can be sent following a request/response pattern or being one-way.\nFor Request/Response commands, devices send their responses to commands by means of sending an MQTT PUBLISH message to a topic that is specific to the command that has been executed. The MQTT adapter accepts responses being published using either QoS 0 or QoS 1.\nThe MQTT adapter checks the configured message limit before accepting any command requests and responses. In case of incoming command requests from business applications, if the message limit is exceeded, the Adapter rejects the message with the reason amqp:resource-limit-exceeded. And for the incoming command responses from devices, the Adapter rejects the message and closes the connection to the client.\nThe following sections define the topic filters/names to use for subscribing to and responding to commands. The following shorthand versions of topic path segments are supported:\n c instead of command q instead of req s instead of res   Note Previous versions of Hono used control instead of command as topic prefix. Using the control prefix is still supported but deprecated.  The following variables are used:\n ${command} : is an arbitrary string that indicates the command to execute, e.g. setBrightness. The command is provided by the application that sends the command. ${req-id} (only for Request/Response commands) : denotes the unique identifier of the command execution request and is passed to the device as part of the name of the topic that the command is published to. The device needs to publish its response to the command to a topic which includes this identifier, thus allowing the adapter to correlate the response with the request. ${status} : is the HTTP status code indicating the outcome of executing the command. This status code is passed on to the application in the AMQP message\u0026rsquo;s status header.  The property-bag is an optional collection of properties intended for the receiver of the message. A property bag is only allowed at the very end of a topic. It always starts with a ? character, followed by pairs of URL encoded property names and values that are separated by \u0026amp;. The following example shows a property bag that contains two properties seqNo and importance:\n/topic/name/?seqNo=10034\u0026amp;importance=\u0026quot;high\u0026quot;  The MQTT adapter currently does not require nor use any properties.\nReceiving Commands (authenticated Device) An authenticated device MUST use the following topic filter to subscribe to commands:\n command/+/+/req/#  Example\nmosquitto_sub -v -u 'sensor1@DEFAULT_TENANT' -P hono-secret -t command/+/+/req/#  The adapter will then publish commands for the device to topic:\n for Request/Response commands: command///req/${req-id}/${command} for one-way commands: command///req//${command}  Example\nFor example, if the HonoExampleApplication was started, after the ttd event requested by the subscription of mosquitto_sub, it layers a command that arrives as follows:\ncommand///q/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/setBrightness { \u0026quot;brightness\u0026quot; : 79 }  If the command is a one-way command, it will arrive as follows:\ncommand///q//setBrightness { \u0026quot;brightness\u0026quot; : 79 }  Receiving Commands (unauthenticated Device) An unauthenticated device MUST use the following topic filter to subscribe to commands:\n command/${tenant-id}/${device-id}/req/#  Example\nmosquitto_sub -v -t command/DEFAULT_TENANT/4711/req/#  The adapter will then publish Request/Response commands for the device to topic:\n command/${tenant-id}/${device-id}/req/${req-id}/${command}  and one-way commands to the topic:\n command/${tenant-id}/${device-id}/req//${command}  (For an example of the incoming command see above at authenticated device)\nReceiving Commands (authenticated Gateway) Gateway components can receive commands for devices which do not connect to a protocol adapter directly but instead are connected to the gateway, e.g. using some low-bandwidth radio based technology like SigFox or LoRa. Corresponding devices have to be configured so that they can be used with a gateway. See Configuring Gateway Devices for details.\nIf a device is configured in such a way that there can be one gateway, acting on behalf of the device, a command sent to this device will by default be directed to that gateway.\nIf a device is configured to be used with multiple gateways, the particular gateway that last acted on behalf of the device will be the target that commands for that device will be routed to. The mapping of device and gateway last used by the device is updated whenever a device sends a telemetry, event or command response message via the gateway. This means that for a device configured to be used via multiple gateways to receive commands, the device first has to send at least one telemetry or event message to establish which gateway to use for receiving commands for that device.\nAn authenticated gateway MUST use the following topic filter to subscribe to to commands for all the devices it acts on behalf of:\n command/+/+/req/#  Example\nmosquitto_sub -v -u 'gw@DEFAULT_TENANT' -P gw-secret -t command/+/+/req/#  The adapter will then publish commands for devices, that the gateway has acted on behalf of, to topic:\n for Request/Response commands: command//${device-id}/req/${req-id}/${command} for one-way commands: command//${device-id}/req//${command}  Sending a Response to a Command (authenticated Device) An authenticated device MUST send the response to a previously received command to the following topic:\n command///res/${req-id}/${status}  Example\nAfter a command has arrived as in the above example, you send a response using the arrived ${req-id}:\nmosquitto_pub -u 'sensor1@DEFAULT_TENANT' -P hono-secret -t command///res/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/200 -m '{\u0026quot;lumen\u0026quot;: 200}'  Sending a Response to a Command (unauthenticated Device) An unauthenticated device MUST send the response to a previously received command to the following topic:\n command/${tenant-id}/${device-id}/res/${req-id}/${status}  Example\nAfter a command has arrived as in the above example, you send a response using the arrived ${req-id}:\nmosquitto_pub -t command/DEFAULT_TENANT/4711/res/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/200 -m '{\u0026quot;lumen\u0026quot;: 200}'  Sending a Response to a Command (authenticated Gateway) An authenticated gateway MUST send the response to a previously received command to the following topic:\n command///res/${req-id}/${status}  Example\nAfter a command has arrived as in the above example, you send a response using the arrived ${req-id}:\nmosquitto_pub -u 'gw@DEFAULT_TENANT' -P gw-secret -t command///res/1010f8ab0b53-bd96-4d99-9d9c-56b868474a6a/200 -m '{\u0026quot;lumen\u0026quot;: 200}'  Downstream Meta Data The adapter includes the following meta data in messages being sent downstream:\n   Name Location Type Description     device_id application string The identifier of the device that the message originates from.   orig_adapter application string Contains the adapter\u0026rsquo;s type name which can be used by downstream consumers to determine the protocol adapter that the message has been received over. The MQTT adapter\u0026rsquo;s type name is hono-mqtt.   orig_address application string Contains the name of the MQTT topic that the device has originally published the data to.   x-opt-retain * message-annotations boolean Contains true if the device has published an event or telemetry message with its retain flag set to 1    The adapter also considers defaults registered for the device at either the tenant or the device level. The values of the default properties are determined as follows:\n If the message already contains a non-empty property of the same name, the value if unchanged. Otherwise, if a default property of the same name is defined in the device\u0026rsquo;s registration information, that value is used. Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.  Note that of the standard AMQP 1.0 message properties only the content-type and ttl can be set this way to a default value.\nEvent Message Time-to-live Events published by devices will usually be persisted by the AMQP Messaging Network in order to support deferred delivery to downstream consumers. In most cases the AMQP Messaging Network can be configured with a maximum time-to-live to apply to the events so that the events will be removed from the persistent store if no consumer has attached to receive the event before the message expires.\nIn order to support environments where the AMQP Messaging Network cannot be configured accordingly, the protocol adapter supports setting a downstream event message\u0026rsquo;s ttl property based on the default ttl and max-ttl values configured for a tenant/device as described in the Tenant API.\nTenant specific Configuration The adapter uses the Tenant API to retrieve tenant specific configuration for adapter type hono-mqtt. The following properties are (currently) supported:\n   Name Type Default Value Description     enabled boolean true If set to false the adapter will reject all data from devices belonging to the tenant.

-	"content": "The AMQP protocol adapter allows clients (devices or gateway components) supporting the AMQP 1.0 protocol to publish messages to Eclipse Hono\u0026trade;\u0026rsquo;s Telemetry, Event and Command \u0026amp; Control endpoints.\nDevice Authentication By default, all Hono protocol adapters require clients (devices or gateway components) to authenticate during connection establishment. This is the preferred way for devices to publish data via protocol adapters. The AMQP adapter supports both the SASL PLAIN and SASL EXTERNAL authentication mechanisms. The former uses a username and password to authenticate to the adapter while the latter uses a client certificate.\nIn this guide, we will give examples for publishing telemetry and events for authenticated (using SASL PLAIN) and unauthenticated clients.\nNB: The AMQP adapter can be configured to allow unauthenticated devices to connect by setting configuration variable HONO_AMQP_AUTHENTICATION_REQUIRED to false.\nSASL PLAIN Authentication The AMQP adapter supports authenticating clients using a username and password. This means that clients need to provide a username and a password when connecting to the AMQP adapter. If the adapter is configured for multi-tenancy (i.e HONO_AMQP_SINGLE_TENANT is set to false), then the username must match the pattern [auth-id@tenant], e.g. sensor1@DEFAULT_TENANT. Otherwise the DEFAULT_TENANT is assumed and the tenant-id can be omitted from the username.\nThe adapter verifies the credentials provided by the client against the credentials that the Credentials Service has on record for the device. If the credentials match, then authentication is successful and the client device can proceed to publish messages to Hono.\nThe examples below refer to devices 4711 and gw-1 of tenant DEFAULT_TENANT using auth-ids sensor1 and gw1 and corresponding passwords. The example deployment as described in the Deployment Guides comes pre-configured with the corresponding entities in its device registry component.\nNB There is a subtle difference between the device identifier (device-id) and the auth-id a device uses for authentication. See Device Identity for a discussion of the concepts.\nSASL EXTERNAL Authentication When a device uses a client certificate for authentication, the TLS handshake is initiated during TCP connection establishment. If no trust anchor is configured for the AMQP adapter, the TLS handshake will succeed only if the certificate has not yet expired. Once the TLS handshake completes and a secure connection is established, the certificate\u0026rsquo;s signature is checked during the SASL handshake. To complete the SASL handshake and authenticate the client, the adapter performs the following steps:\n Adapter extracts the client certificate\u0026rsquo;s Issuer DN and uses it to us the Tenant service to look up the tenant that the client belongs to. In order for the lookup to succeed, the tenant’s trust anchor needs to be configured by means of registering the trusted certificate authority. If the lookup succeeds, the Tenant service returns the tenant, thus implicitly establishing the tenant that the device belongs to. Adapter validates the device’s client certificate using the registered trust anchor for the tenant. Finally, adapter authenticates the client certificate using Hono\u0026rsquo;s credentials API. In this step, the adapter uses the client certificate’s Subject DN (as authentication identifier) and x509-cert (for the credentials type) in order to determine the device ID.  NB: The AMQP adapter needs to be configured for TLS in order to support this mechanism.\nConnection Limits After verifying the credentials, the number of existing connections is checked against the configured resource-limits by the AMQP adapter. If the limit is exceeded then the connection request is not accepted.\nMessage Limits Before accepting any telemetry or event or command messages, the AMQP adapter verifies that the configured message limit is not exceeded. The incoming message is discarded if the limit is exceeded.\nLink Establishment Clients can publish all types of messages to the AMQP adapter via a single anonymous sender link. Using AT MOST ONCE delivery semantics, the client will not wait for the message to be accepted and settled by the downstream consumer. However, with AT LEAST ONCE, the client sends the message and waits for the message to be delivered to and accepted by the downstream consumer. If the message cannot be delivered due to a failure, the client will be notified.\nThe client indicates its preferred message delivery mode by means of the snd-settle-mode and rcv-settle-mode fields of its attach frame during link establishment. Clients should use mixed as the snd-settle-mode and first as the rcv-settle-mode in order to be able to use the same link for sending all types of messages using different delivery semantics as described in the following sections.\nError Handling The AMQP adapter distinguishes between two types of errors when a message is published using at least once:\n An error caused by the client side, e.g invalid message address, content-type, adapter disabled for tenant etc. An error caused by the server side, e.g no downstream consumers registered, downstream connection loss etc.  For a client side error, the adapter settles the message transfer with the rejected outcome and provides an error description in the corresponding disposition frame. In the case of a server-side error, the adapter settles the message with the released outcome, indicating to the client that the message itself was OK but it cannot be delivered due to a failure beyond the control of the client. In the latter case, a client may attempt to re-send the message unaltered.\nAMQP Command-line Client For purposes of demonstrating the usage of the AMQP adapter, the Hono CLI Module contains an AMQP command-line client for interacting with the AMQP adapter. The client can be used to send telemetry or events and to receive/respond to command request messages.\nThe command-line client supports the following parameters (with default values):\n --spring.profiles.active=amqp-send: Profile for sending telemetry data or events to Hono. --spring.profiles.active=amqp-command: Profile for receiving and responding to command request messages. --message.address: The AMQP 1.0 message address (default: telemetry) --message.payload: The message payload body (default: '{\u0026quot;temp\u0026quot;: 5}') --hono.client.host: The host name that the AMQP adapter is running on (default: localhost) --hono.client.port: The port that the adapter is listening for incoming connections (default: 5672)  To run the client to send a telemetry message to Hono, open a terminal and execute the following:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=sensor1@DEFAULT_TENANT --hono.client.password=hono-secret Accepted{}  The client prints the outcome of the operation to standard out. The outcome above (Accepted) indicates that the request to upload the data has succeeded.\nNB There are two JAR files in the hono/cli/target directory. The JAR to use for the client is the hono-cli-$VERSION-exec.jar and not the hono-cli-$VERSION.jar file. Running the latter will not work and will output the message: no main manifest attribute, in hono-cli-$VERSION.jar\nPublishing Telemetry Data The client indicates the delivery mode to use when uploading telemetry messages by means of the settled and rcv-settle-mode properties of the AMQP transfer frame(s) it uses for uploading the message. The AMQP adapter will accept messages using a delivery mode according to the following table:\n   settled rcv-settle-mode Delivery semantics     false first The adapter will forward the message to the downstream AMQP 1.0 Messaging Network and will forward any AMQP disposition frame received from the AMQP 1.0 Messaging Network to the client as is. It is up to the client\u0026rsquo;s discretion if and how it processes the disposition frame. The adapter will accept any re-delivered message. Sending unsettled messages allows for clients to implement either AT LEAST ONCE or AT MOST ONCE delivery semantics, depending on whether a client actually waits for and considers the disposition frames it receives from the adapter or not. This is the recommended mode for uploading telemetry data.   true first The adapter will acknowledge and settle any received message spontaneously before forwarding it to the downstream AMQP 1.0 Messaging Network. The adapter will ignore any AMQP disposition frames it receives from the AMQP 1.0 Messaging Network. Sending pre-settled messages allows for clients to implement AT MOST ONCE delivery semantics only. This is the fastest mode of delivery but has the drawback of less reliable end-to-end flow control and potential loss of messages without notice.    All other combinations are not supported by the adapter and will result in the message being ignored (pre-settled) or rejected (unsettled).\nPublish Telemetry Data (authenticated Device) The AMQP adapter supports publishing of telemetry data to Hono\u0026rsquo;s Telemetry API. Telemetry messages can be published using either AT LEAST ONCE or AT MOST ONCE delivery semantics.\n Message Address: telemetry or t  This refers to the to property of the message.  Settlement Mode: presettled (AT MOST ONCE) or unsettled (AT LEAST ONCE) Authentication: SASL PLAIN or SASL EXTERNAL Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to one of the following:  (hono:bad-request): Request rejected due to a bad client request. (amqp:unauthorized-access): Request rejected because the adapter is disabled for tenant. (amqp:precondition-failed): Request does not fulfill certain requirements e.g adapter cannot assert device registration etc. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    When a device publishes data to the telemetry address, the AMQP adapter automatically determines the device\u0026rsquo;s identity and tenant during the authentication process.\nExample\nPublish some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=sensor1@DEFAULT_TENANT --hono.client.password=hono-secret  Notice that we only supplied a new value for the message address, leaving the other default values.\nPublish some JSON data for device 4711 using a client certificate for authentication:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.port=5671 --hono.client.certPath=config/hono-demo-certs-jar/device-4711-cert.pem --hono.client.keyPath=config/hono-demo-certs-jar/device-4711-key.pem --hono.client.trustStorePath=config/hono-demo-certs-jar/trusted-certs.pem --hono.client.hostnameVerificationRequired=false  Publish Telemetry Data (unauthenticated Device)  Message Address: telemetry/${tenant-id}/${device-id} or t/${tenant-id}/${device-id} Settlement Mode: presettled (AT MOST ONCE) or unsettled (AT LEAST ONCE) Authentication: none Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to:  (hono:bad-request): A bad client request (e.g invalid content-type). (amqp:unauthorized-access): The adapter is disabled for tenant. (amqp:precondition-failed): Request not fulfilling certain requirements. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    Note how verbose the address is for unauthenticated devices. This address can be used by devices that have not authenticated to the protocol adapter. This requires the HONO_AMQP_AUTHENTICATION_REQUIRED configuration property to be explicitly set to false before starting the protocol adapter.\nExamples\nPublish some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --message.address=t/DEFAULT_TENANT/4711  Publish Telemetry Data (authenticated Gateway) A device that publishes data on behalf of another device is called a gateway device. The message address is used by gateway components to publish data on behalf of other devices which do not connect to a protocol adapter directly but instead are connected to the gateway, e.g. using some low-bandwidth radio based technology like SigFox or LoRa. In this case the credentials provided by the gateway during connection establishment with the protocol adapter are used to authenticate the gateway whereas the message address is used to identify the device that the gateway publishes data for.\nExamples\nA gateway connecting to the adapter using gw@DEFAULT_TENANT as username and gw-secret as password and then publishing some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=gw@DEFAULT_TENANT --hono.client.password=gw-secret --message.address=t/DEFAULT_TENANT/4711  In this example, we are using message address t/DEFAULT_TENANT/4711 which contains the device that the gateway is publishing the message for.\nPublishing Events The adapter supports AT LEAST ONCE delivery of Event messages only. A client therefore MUST set the settled property to false and the rcv-settle-mode property to first in all transfer frame(s) it uses for uploading events. All other combinations are not supported by the adapter and result in the message being rejected.\nPublish an Event (authenticated Device)  Message Address: event or e Settlement Mode: unsettled (AT LEAST ONCE) Authentication: SASL PLAIN or SASL EXTERNAL Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to:  (hono:bad-request): A bad client request (e.g invalid content-type). (amqp:unauthorized-access): The adapter is disabled for tenant. (amqp:precondition-failed): Request not fulfilling certain requirements. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    This is the preferred way for devices to publish events. It is available only if the protocol adapter has been configured to require devices to authenticate (which is the default).\nExample\nUpload a JSON string for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=sensor1@DEFAULT_TENANT --hono.client.password=hono-secret --message.address=event --message.payload='{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (unauthenticated Device)  Message Address: event/${tenant-id}/${device-id} or e/${tenant-id}/${device-id} Settlement Mode: unsettled (AT LEAST ONCE) Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to:  (hono:bad-request): A bad client request (e.g invalid content-type). (amqp:unauthorized-access): The adapter is disabled for tenant. (amqp:precondition-failed): Request not fulfilling certain requirements. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    This address format is used by devices that have not authenticated to the protocol adapter. Note that this requires the HONO_AMQP_AUTHENTICATION_REQUIRED configuration property to be explicitly set to false.\nExamples\nPublish some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --message.address=e/DEFAULT_TENANT/4711 --message.payload='{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (authenticated Gateway) Examples\nA gateway connecting to the adapter using gw@DEFAULT_TENANT as username and gw-secret as password and then publishing some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=gw@DEFAULT_TENANT --hono.client.password=gw-secret --message.address=e/DEFAULT_TENANT/4711  In this example, we are using message address e/DEFAULT_TENANT/4711 which contains the device that the gateway is publishing the message for.\nCommand \u0026amp; Control The AMQP adapter supports devices to receive commands that have been sent by business applications by means of opening a receiver link using a device specific source address as described below. When a device no longer wants to receive commands anymore, it can simply close the link.\nWhen a device has successfully opened a receiver link for commands, the adapter sends an empty notification on behalf of the device to the downstream AMQP 1.0 Messaging Network with the ttd header set to -1, indicating that the device will be ready to receive commands until further notice. Analogously, the adapter sends an empty notification with the ttd header set to 0 when a device closes the link or disconnects.\nDevices send their responses to commands by means of sending an AMQP message with properties specific to the command that has been executed. The AMQP adapter accepts responses being published using either at most once (QoS 0) or at least once (QoS 1) delivery semantics. The device must send the command response messages using the same (sender) link that it uses for sending telemetry data and events.\nThe AMQP adapter checks the configured message limit before accepting any command requests and responses. In case of incoming command requests from business applications or the command responses from devices, if the message limit is exceeded, the Adapter rejects the message with the reason amqp:resource-limit-exceeded.\nReceiving Commands A device MUST use the following source address in its attach frame to open a link for receiving commands:\n command (authenticated device/gateway) command/${tenant}/${device-id} (unauthenticated device)   Note Previous versions of Hono used control instead of command as address prefix. Using the control prefix is still supported but deprecated.  The adapter supports AT LEAST ONCE delivery of command messages only. A client therefore MUST use unsettled for the snd-settle-mode and first for the rcv-settle-mode fields of its attach frame during link establishment. All other combinations are not supported and result in the termination of the link.\nOnce the link has been established, the adapter will send command messages having the following properties:\n   Name Mandatory Location Type Description     subject yes properties string Contains the name of the command to be executed.   reply-to no properties string Contains the address to which the command response should be sent. This property will be empty for one-way commands.   correlation-id no properties string This property will be empty for one-way commands, otherwise it will contain the identifier used to correlate the response with the command request.   device_id no application-properties string This property will only be set if an authenticated gateway has connected to the adapter. It will contain the id of the device (connected to the gateway) that the command is targeted at.    Authenticated gateways will receive commands for devices which do not connect to a protocol adapter directly but instead are connected to the gateway. Corresponding devices have to be configured so that they can be used with a gateway. See Configuring Gateway Devices for details.\nIf a device is configured in such a way that there can be one gateway, acting on behalf of the device, a command sent to this device will by default be directed to that gateway.\nIf a device is configured to be used with multiple gateways, the particular gateway that last acted on behalf of the device will be the target that commands for that device will be routed to. The mapping of device and gateway last used by the device is updated whenever a device sends a telemetry, event or command response message via the gateway. This means that for a device configured to be used via multiple gateways to receive commands, the device first has to send at least one telemetry or event message to establish which gateway to use for receiving commands for that device.\nSending a Response to a Command A device only needs to respond to commands that contain a reply-to address and a correlation-id. However, if the application expects a response, then devices must publish a response back to the application. Devices may use the same anonymous sender link for this purpose that they also use for sending telemetry data and events.\nThe adapter supports AT LEAST ONCE delivery of command response messages only. A client therefore MUST set the settled property to true and the rcv-settle-mode property to first in all transfer frame(s) it uses for uploading command responses. All other combinations are not supported by the adapter and result in the message being rejected.\nThe table below provides an overview of the properties that must be set on a command response message:\n   Name Mandatory Location Type Description     to yes properties string MUST contain the value of the reply-to property of the command request message.   correlation-id yes properties string MUST contain the value of the correlation-id property of the command request message.   status yes application-properties integer MUST contain a status code indicating the outcome of processing the command at the device (see Command \u0026amp; Control API for details).

The AMQP adapter\u0026rsquo;s type name is hono-amqp.   orig_address string Contains the AMQP target address that the device has used to send the data.    The adapter also considers defaults registered for the device at either the tenant or the device level. The values of the default properties are determined as follows:\n If the message already contains a non-empty property of the same name, the value if unchanged. Otherwise, if a default property of the same name is defined in the device\u0026rsquo;s registration information, that value is used.

Note that of the standard AMQP 1.0 message properties only the content-type and ttl can be set this way to a default value.\nEvent Message Time-to-live Events published by devices will usually be persisted by the AMQP Messaging Network in order to support deferred delivery to downstream consumers. In most cases the AMQP Messaging Network can be configured with a maximum time-to-live to apply to the events so that the events will be removed from the persistent store if no consumer has attached to receive the event before the message expires.\nIn order to support environments where the AMQP Messaging Network cannot be configured accordingly, the protocol adapter supports setting a downstream event message\u0026rsquo;s ttl property based on the default ttl and max-ttl values configured for a tenant/device as described in the Tenant API.\nTenant specific Configuration The adapter uses the Tenant API to retrieve tenant specific configuration for adapter type hono-amqp. The following properties are (currently) supported:\n   Name Type Default Value Description     enabled boolean true If set to false the adapter will reject all data from devices belonging to the tenant and respond with a amqp:unauthorized-access as the error condition value for rejecting the message.

+	"content": "The AMQP protocol adapter allows clients (devices or gateway components) supporting the AMQP 1.0 protocol to publish messages to Eclipse Hono\u0026trade;\u0026rsquo;s Telemetry, Event and Command \u0026amp; Control endpoints.\nDevice Authentication By default, all Hono protocol adapters require clients (devices or gateway components) to authenticate during connection establishment. This is the preferred way for devices to publish data via protocol adapters. The AMQP adapter supports both the SASL PLAIN and SASL EXTERNAL authentication mechanisms. The former uses a username and password to authenticate to the adapter while the latter uses a client certificate.\nIn this guide, we will give examples for publishing telemetry and events for authenticated (using SASL PLAIN) and unauthenticated clients.\nNB: The AMQP adapter can be configured to allow unauthenticated devices to connect by setting configuration variable HONO_AMQP_AUTHENTICATION_REQUIRED to false.\nSASL PLAIN Authentication The AMQP adapter supports authenticating clients using a username and password. This means that clients need to provide a username and a password when connecting to the AMQP adapter. If the adapter is configured for multi-tenancy (i.e HONO_AMQP_SINGLE_TENANT is set to false), then the username must match the pattern [auth-id@tenant], e.g. sensor1@DEFAULT_TENANT. Otherwise the DEFAULT_TENANT is assumed and the tenant-id can be omitted from the username.\nThe adapter verifies the credentials provided by the client against the credentials that the Credentials Service has on record for the device. If the credentials match, then authentication is successful and the client device can proceed to publish messages to Hono.\nThe examples below refer to devices 4711 and gw-1 of tenant DEFAULT_TENANT using auth-ids sensor1 and gw1 and corresponding passwords. The example deployment as described in the Deployment Guides comes pre-configured with the corresponding entities in its device registry component.\nNB There is a subtle difference between the device identifier (device-id) and the auth-id a device uses for authentication. See Device Identity for a discussion of the concepts.\nSASL EXTERNAL Authentication When a device uses a client certificate for authentication, the TLS handshake is initiated during TCP connection establishment. If no trust anchor is configured for the AMQP adapter, the TLS handshake will succeed only if the certificate has not yet expired. Once the TLS handshake completes and a secure connection is established, the certificate\u0026rsquo;s signature is checked during the SASL handshake. To complete the SASL handshake and authenticate the client, the adapter performs the following steps:\n Adapter extracts the client certificate\u0026rsquo;s Issuer DN and uses it to us the Tenant service to look up the tenant that the client belongs to. In order for the lookup to succeed, the tenant’s trust anchor needs to be configured by means of registering the trusted certificate authority. If the lookup succeeds, the Tenant service returns the tenant, thus implicitly establishing the tenant that the device belongs to. Adapter validates the device’s client certificate using the registered trust anchor for the tenant. Finally, adapter authenticates the client certificate using Hono\u0026rsquo;s credentials API. In this step, the adapter uses the client certificate’s Subject DN (as authentication identifier) and x509-cert (for the credentials type) in order to determine the device ID.  NB: The AMQP adapter needs to be configured for TLS in order to support this mechanism.\nConnection Limits After verifying the credentials, the number of existing connections is checked against the configured resource-limits by the AMQP adapter. If the limit is exceeded then the connection request is not accepted.\nMessage Limits Before accepting any telemetry or event or command messages, the AMQP adapter verifies that the configured message limit is not exceeded. The incoming message is discarded if the limit is exceeded.\nConnection Event The AMQP Adapter can send a Connection Event once the connection with a device has been successfully established or ended. Note that this requires the HONO_CONNECTION_EVENTS_PRODUCER configuration property to be explicitly set to events.\nLink Establishment Clients can publish all types of messages to the AMQP adapter via a single anonymous sender link. Using AT MOST ONCE delivery semantics, the client will not wait for the message to be accepted and settled by the downstream consumer. However, with AT LEAST ONCE, the client sends the message and waits for the message to be delivered to and accepted by the downstream consumer. If the message cannot be delivered due to a failure, the client will be notified.\nThe client indicates its preferred message delivery mode by means of the snd-settle-mode and rcv-settle-mode fields of its attach frame during link establishment. Clients should use mixed as the snd-settle-mode and first as the rcv-settle-mode in order to be able to use the same link for sending all types of messages using different delivery semantics as described in the following sections.\nError Handling The AMQP adapter distinguishes between two types of errors when a message is published using at least once:\n An error caused by the client side, e.g invalid message address, content-type, adapter disabled for tenant etc. An error caused by the server side, e.g no downstream consumers registered, downstream connection loss etc.  For a client side error, the adapter settles the message transfer with the rejected outcome and provides an error description in the corresponding disposition frame. In the case of a server-side error, the adapter settles the message with the released outcome, indicating to the client that the message itself was OK but it cannot be delivered due to a failure beyond the control of the client. In the latter case, a client may attempt to re-send the message unaltered.\nAMQP Command-line Client For purposes of demonstrating the usage of the AMQP adapter, the Hono CLI Module contains an AMQP command-line client for interacting with the AMQP adapter. The client can be used to send telemetry or events and to receive/respond to command request messages.\nThe command-line client supports the following parameters (with default values):\n --spring.profiles.active=amqp-send: Profile for sending telemetry data or events to Hono. --spring.profiles.active=amqp-command: Profile for receiving and responding to command request messages. --message.address: The AMQP 1.0 message address (default: telemetry) --message.payload: The message payload body (default: '{\u0026quot;temp\u0026quot;: 5}') --hono.client.host: The host name that the AMQP adapter is running on (default: localhost) --hono.client.port: The port that the adapter is listening for incoming connections (default: 5672)  To run the client to send a telemetry message to Hono, open a terminal and execute the following:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=sensor1@DEFAULT_TENANT --hono.client.password=hono-secret Accepted{}  The client prints the outcome of the operation to standard out. The outcome above (Accepted) indicates that the request to upload the data has succeeded.\nNB There are two JAR files in the hono/cli/target directory. The JAR to use for the client is the hono-cli-$VERSION-exec.jar and not the hono-cli-$VERSION.jar file. Running the latter will not work and will output the message: no main manifest attribute, in hono-cli-$VERSION.jar\nPublishing Telemetry Data The client indicates the delivery mode to use when uploading telemetry messages by means of the settled and rcv-settle-mode properties of the AMQP transfer frame(s) it uses for uploading the message. The AMQP adapter will accept messages using a delivery mode according to the following table:\n   settled rcv-settle-mode Delivery semantics     false first The adapter will forward the message to the downstream AMQP 1.0 Messaging Network and will forward any AMQP disposition frame received from the AMQP 1.0 Messaging Network to the client as is. It is up to the client\u0026rsquo;s discretion if and how it processes the disposition frame. The adapter will accept any re-delivered message. Sending unsettled messages allows for clients to implement either AT LEAST ONCE or AT MOST ONCE delivery semantics, depending on whether a client actually waits for and considers the disposition frames it receives from the adapter or not. This is the recommended mode for uploading telemetry data.   true first The adapter will acknowledge and settle any received message spontaneously before forwarding it to the downstream AMQP 1.0 Messaging Network. The adapter will ignore any AMQP disposition frames it receives from the AMQP 1.0 Messaging Network. Sending pre-settled messages allows for clients to implement AT MOST ONCE delivery semantics only. This is the fastest mode of delivery but has the drawback of less reliable end-to-end flow control and potential loss of messages without notice.    All other combinations are not supported by the adapter and will result in the message being ignored (pre-settled) or rejected (unsettled).\nPublish Telemetry Data (authenticated Device) The AMQP adapter supports publishing of telemetry data to Hono\u0026rsquo;s Telemetry API. Telemetry messages can be published using either AT LEAST ONCE or AT MOST ONCE delivery semantics.\n Message Address: telemetry or t  This refers to the to property of the message.  Settlement Mode: presettled (AT MOST ONCE) or unsettled (AT LEAST ONCE) Authentication: SASL PLAIN or SASL EXTERNAL Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to one of the following:  (hono:bad-request): Request rejected due to a bad client request. (amqp:unauthorized-access): Request rejected because the adapter is disabled for tenant. (amqp:precondition-failed): Request does not fulfill certain requirements e.g adapter cannot assert device registration etc. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    When a device publishes data to the telemetry address, the AMQP adapter automatically determines the device\u0026rsquo;s identity and tenant during the authentication process.\nExample\nPublish some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=sensor1@DEFAULT_TENANT --hono.client.password=hono-secret  Notice that we only supplied a new value for the message address, leaving the other default values.\nPublish some JSON data for device 4711 using a client certificate for authentication:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.port=5671 --hono.client.certPath=config/hono-demo-certs-jar/device-4711-cert.pem --hono.client.keyPath=config/hono-demo-certs-jar/device-4711-key.pem --hono.client.trustStorePath=config/hono-demo-certs-jar/trusted-certs.pem --hono.client.hostnameVerificationRequired=false  Publish Telemetry Data (unauthenticated Device)  Message Address: telemetry/${tenant-id}/${device-id} or t/${tenant-id}/${device-id} Settlement Mode: presettled (AT MOST ONCE) or unsettled (AT LEAST ONCE) Authentication: none Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to:  (hono:bad-request): A bad client request (e.g invalid content-type). (amqp:unauthorized-access): The adapter is disabled for tenant. (amqp:precondition-failed): Request not fulfilling certain requirements. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    Note how verbose the address is for unauthenticated devices. This address can be used by devices that have not authenticated to the protocol adapter. This requires the HONO_AMQP_AUTHENTICATION_REQUIRED configuration property to be explicitly set to false before starting the protocol adapter.\nExamples\nPublish some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --message.address=t/DEFAULT_TENANT/4711  Publish Telemetry Data (authenticated Gateway) A device that publishes data on behalf of another device is called a gateway device. The message address is used by gateway components to publish data on behalf of other devices which do not connect to a protocol adapter directly but instead are connected to the gateway, e.g. using some low-bandwidth radio based technology like SigFox or LoRa. In this case the credentials provided by the gateway during connection establishment with the protocol adapter are used to authenticate the gateway whereas the message address is used to identify the device that the gateway publishes data for.\nExamples\nA gateway connecting to the adapter using gw@DEFAULT_TENANT as username and gw-secret as password and then publishing some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=gw@DEFAULT_TENANT --hono.client.password=gw-secret --message.address=t/DEFAULT_TENANT/4711  In this example, we are using message address t/DEFAULT_TENANT/4711 which contains the device that the gateway is publishing the message for.\nPublishing Events The adapter supports AT LEAST ONCE delivery of Event messages only. A client therefore MUST set the settled property to false and the rcv-settle-mode property to first in all transfer frame(s) it uses for uploading events. All other combinations are not supported by the adapter and result in the message being rejected.\nPublish an Event (authenticated Device)  Message Address: event or e Settlement Mode: unsettled (AT LEAST ONCE) Authentication: SASL PLAIN or SASL EXTERNAL Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to:  (hono:bad-request): A bad client request (e.g invalid content-type). (amqp:unauthorized-access): The adapter is disabled for tenant. (amqp:precondition-failed): Request not fulfilling certain requirements. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    This is the preferred way for devices to publish events. It is available only if the protocol adapter has been configured to require devices to authenticate (which is the default).\nExample\nUpload a JSON string for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=sensor1@DEFAULT_TENANT --hono.client.password=hono-secret --message.address=event --message.payload='{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (unauthenticated Device)  Message Address: event/${tenant-id}/${device-id} or e/${tenant-id}/${device-id} Settlement Mode: unsettled (AT LEAST ONCE) Message Body:  (optional) Arbitrary payload  Message properties:  (optional) Arbitrary properties (content-type, correlation-id, \u0026hellip;)  Disposition Frames:  Accepted: Message successfully processed by the adapter. Released: Message cannot be processed and should be redelivered. Rejected: Adapter rejects the message due to:  (hono:bad-request): A bad client request (e.g invalid content-type). (amqp:unauthorized-access): The adapter is disabled for tenant. (amqp:precondition-failed): Request not fulfilling certain requirements. (amqp:resource-limit-exceeded): Request rejected because the message limit for the given tenant is exceeded.    This address format is used by devices that have not authenticated to the protocol adapter. Note that this requires the HONO_AMQP_AUTHENTICATION_REQUIRED configuration property to be explicitly set to false.\nExamples\nPublish some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --message.address=e/DEFAULT_TENANT/4711 --message.payload='{\u0026quot;alarm\u0026quot;: 1}'  Publish an Event (authenticated Gateway) Examples\nA gateway connecting to the adapter using gw@DEFAULT_TENANT as username and gw-secret as password and then publishing some JSON data for device 4711:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-send --hono.client.username=gw@DEFAULT_TENANT --hono.client.password=gw-secret --message.address=e/DEFAULT_TENANT/4711  In this example, we are using message address e/DEFAULT_TENANT/4711 which contains the device that the gateway is publishing the message for.\nCommand \u0026amp; Control The AMQP adapter supports devices to receive commands that have been sent by business applications by means of opening a receiver link using a device specific source address as described below. When a device no longer wants to receive commands anymore, it can simply close the link.\nWhen a device has successfully opened a receiver link for commands, the adapter sends an empty notification on behalf of the device to the downstream AMQP 1.0 Messaging Network with the ttd header set to -1, indicating that the device will be ready to receive commands until further notice. Analogously, the adapter sends an empty notification with the ttd header set to 0 when a device closes the link or disconnects.\nDevices send their responses to commands by means of sending an AMQP message with properties specific to the command that has been executed. The AMQP adapter accepts responses being published using either at most once (QoS 0) or at least once (QoS 1) delivery semantics. The device must send the command response messages using the same (sender) link that it uses for sending telemetry data and events.\nThe AMQP adapter checks the configured message limit before accepting any command requests and responses. In case of incoming command requests from business applications or the command responses from devices, if the message limit is exceeded, the Adapter rejects the message with the reason amqp:resource-limit-exceeded.\nReceiving Commands A device MUST use the following source address in its attach frame to open a link for receiving commands:\n command (authenticated device/gateway) command/${tenant}/${device-id} (unauthenticated device)   Note Previous versions of Hono used control instead of command as address prefix. Using the control prefix is still supported but deprecated.  The adapter supports AT LEAST ONCE delivery of command messages only. A client therefore MUST use unsettled for the snd-settle-mode and first for the rcv-settle-mode fields of its attach frame during link establishment. All other combinations are not supported and result in the termination of the link.\nOnce the link has been established, the adapter will send command messages having the following properties:\n   Name Mandatory Location Type Description     subject yes properties string Contains the name of the command to be executed.   reply-to no properties string Contains the address to which the command response should be sent. This property will be empty for one-way commands.   correlation-id no properties string This property will be empty for one-way commands, otherwise it will contain the identifier used to correlate the response with the command request.   device_id no application-properties string This property will only be set if an authenticated gateway has connected to the adapter. It will contain the id of the device (connected to the gateway) that the command is targeted at.    Authenticated gateways will receive commands for devices which do not connect to a protocol adapter directly but instead are connected to the gateway. Corresponding devices have to be configured so that they can be used with a gateway. See Configuring Gateway Devices for details.\nIf a device is configured in such a way that there can be one gateway, acting on behalf of the device, a command sent to this device will by default be directed to that gateway.\nIf a device is configured to be used with multiple gateways, the particular gateway that last acted on behalf of the device will be the target that commands for that device will be routed to. The mapping of device and gateway last used by the device is updated whenever a device sends a telemetry, event or command response message via the gateway. This means that for a device configured to be used via multiple gateways to receive commands, the device first has to send at least one telemetry or event message to establish which gateway to use for receiving commands for that device.\nSending a Response to a Command A device only needs to respond to commands that contain a reply-to address and a correlation-id. However, if the application expects a response, then devices must publish a response back to the application. Devices may use the same anonymous sender link for this purpose that they also use for sending telemetry data and events.\nThe adapter supports AT LEAST ONCE delivery of command response messages only. A client therefore MUST set the settled property to true and the rcv-settle-mode property to first in all transfer frame(s) it uses for uploading command responses. All other combinations are not supported by the adapter and result in the message being rejected.\nThe table below provides an overview of the properties that must be set on a command response message:\n   Name Mandatory Location Type Description     to yes properties string MUST contain the value of the reply-to property of the command request message.   correlation-id yes properties string MUST contain the value of the correlation-id property of the command request message.   status yes application-properties integer MUST contain a status code indicating the outcome of processing the command at the device (see Command \u0026amp; Control API for details).    Examples The AMQP adapter client can be used to simulate a device which receives commands and sends responses back to the application. The command line client is used to simulate an application sending commands to devices and receiving command responses from devices.\nStart the AMQP adapter client, as follows:\n# in directory: hono/cli/target/ java -jar hono-cli-*-exec.jar --spring.profiles.active=amqp-command --hono.client.username=sensor1@DEFAULT_TENANT --hono.client.password=hono-secret Device is now ready to receive commands (Press Ctrl + c to terminate)  After successfully starting the client, a message indicating that the device is ready to receive commands will be printed to standard output. The device is now waiting to receive commands from applications. To send a command to the device, open a new terminal shell and start the command application, as shown below:\n# in directory: hono/cli/ java -jar target/hono-cli-*-exec.jar --hono.client.host=localhost --hono.client.username=consumer@HONO --hono.client.password=verysecret --spring.profiles.active=command,ssl \u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt; Enter name of command for device [DEFAULT_TENANT:4711] (prefix with 'ow:' to send one-way command): setBrightness \u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt; Enter command payload: some-payload \u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt;\u0026gt; Enter content type: text/plain   Note Change into the cli directory before running the command above to start the command application. If you change into the target directory (i.e cli/target), then the client will not be able to locate to certificate needed to connect to the messaging network.  Once the command application starts successfully, enter a command name, payload and content-type of the command to send to the device.\nAfter sending the command, the device (i.e AMQP command client) will print out the command name and payload that it receives and automatically sends a command response to the application.\n$ Received Command Message : [Command name: setBrightness, Command payload: some-payload] $ Command response sent [outcome: Accepted{}]  Downstream Meta Data The adapter includes the following meta data in the application properties of messages being sent downstream:\n   Name Type Description     device_id string The identifier of the device that the message originates from.   orig_adapter string Contains the adapter\u0026rsquo;s type name which can be used by downstream consumers to determine the protocol adapter that the message has been received over. The AMQP adapter\u0026rsquo;s type name is hono-amqp.   orig_address string Contains the AMQP target address that the device has used to send the data.    The adapter also considers defaults registered for the device at either the tenant or the device level. The values of the default properties are determined as follows:\n If the message already contains a non-empty property of the same name, the value if unchanged. Otherwise, if a default property of the same name is defined in the device\u0026rsquo;s registration information, that value is used. Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.  Note that of the standard AMQP 1.0 message properties only the content-type and ttl can be set this way to a default value.\nEvent Message Time-to-live Events published by devices will usually be persisted by the AMQP Messaging Network in order to support deferred delivery to downstream consumers. In most cases the AMQP Messaging Network can be configured with a maximum time-to-live to apply to the events so that the events will be removed from the persistent store if no consumer has attached to receive the event before the message expires.\nIn order to support environments where the AMQP Messaging Network cannot be configured accordingly, the protocol adapter supports setting a downstream event message\u0026rsquo;s ttl property based on the default ttl and max-ttl values configured for a tenant/device as described in the Tenant API.\nTenant specific Configuration The adapter uses the Tenant API to retrieve tenant specific configuration for adapter type hono-amqp. The following properties are (currently) supported:\n   Name Type Default Value Description     enabled boolean true If set to false the adapter will reject all data from devices belonging to the tenant and respond with a amqp:unauthorized-access as the error condition value for rejecting the message.

 <p>Clients can publish all types of messages to the AMQP adapter via a single <em>anonymous</em> sender link.

However, with <em>AT LEAST ONCE</em>, the client sends the message and waits for the message to be delivered to and accepted by the downstream consumer.
