+<p>The AMQP protocol adapter allows clients (devices or gateway components) supporting the AMQP 1.0 protocol to publish messages to Eclipse Hono™&rsquo;s Telemetry, Event and Command &amp; Control endpoints.</p>
 <h2 id="device-authentication">Device Authentication</h2>
-
 <p>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
 <a href="https://tools.ietf.org/html/rfc4616">SASL PLAIN</a> and <a href="https://tools.ietf.org/html/rfc4422">SASL EXTERNAL</a> authentication mechanisms.
 The former uses a <em>username</em> and <em>password</em> to authenticate to the adapter while the latter uses an X.509 client certificate.</p>
-
 <p>This guide provides examples for publishing telemetry and events for <em>authenticated</em> (using SASL PLAIN) and <em>unauthenticated</em> clients.</p>
-
 <p><strong>NB</strong> The AMQP adapter can be configured to <em>allow</em> unauthenticated devices to connect by setting configuration variable
 <code>HONO_AMQP_AUTHENTICATION_REQUIRED</code> to <code>false</code>.</p>
-
 <h3 id="sasl-plain-authentication">SASL PLAIN Authentication</h3>
-
 <p>The AMQP adapter supports authenticating clients using a <em>username</em> and <em>password</em>. This means that clients need to provide a <em>username</em> and a <em>password</em>
 when connecting to the AMQP adapter. If the adapter is configured for multi-tenancy (i.e <code>HONO_AMQP_SINGLE_TENANT</code> is set to <code>false</code>),
 then the <em>username</em> must match the pattern [<em>auth-id@tenant</em>], e.g. <code>sensor1@DEFAULT_TENANT</code>. Otherwise, the tenant-id can be omitted from the username
 and the client is assumed to belong to the <code>DEFAULT_TENANT</code>.</p>
-
 <p>The adapter verifies the credentials provided by the client against the credentials that the
 <a href="/hono/docs/1.4/admin-guide/common-config/#credentials-service-connection-configuration">configured Credentials service</a> has on record for the client.
 If the credentials match, the client device can proceed to publish messages to Hono.</p>
-
 <p>The examples below refer to devices <code>4711</code> and <code>gw-1</code> of tenant <code>DEFAULT_TENANT</code> using <em>auth-ids</em> <code>sensor1</code> and <code>gw1</code> and corresponding passwords.
 The example deployment as described in the <a href="/hono/docs/1.4/deployment/">Deployment Guide</a> comes pre-configured with the corresponding entities in its
 device registry component.</p>
-
 <p><strong>NB</strong> There is a subtle difference between the <em>device identifier</em> (<em>device-id</em>) and the <em>auth-id</em> a device uses for authentication.
 See <a href="/hono/docs/1.4/concepts/device-identity/">Device Identity</a> for a discussion of the concepts.</p>
-
 <h3 id="sasl-external-authentication">SASL EXTERNAL Authentication</h3>
-
 <p>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&rsquo;s signature is checked during the SASL handshake.
 To complete the SASL handshake and authenticate the client, the adapter performs the following steps:</p>
-
 <ol>
 <li>The adapter extracts the client certificate&rsquo;s <em>Issuer DN</em> from the client certificate</li>
 <li>The adapter invokes the Tenant service to look up the tenant matching the DN.

 uses the client certificate’s <em>Subject DN</em> (as authentication identifier) and <code>x509-cert</code> (for the credentials type)

-
 <p>The AMQP adapter supports the <a href="http://docs.oasis-open.org/amqp/anonterm/v1.0/anonterm-v1.0.html">Anonymous Terminus for Message Routing</a> specification
 and requires clients to create a single sender link using the <code>null</code> target address for publishing all types of messages to the AMQP adapter.</p>
-
 <p>Using <em>AT MOST ONCE</em> delivery semantics, the client will not wait for the message to be accepted and settled by the downstream consumer. 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. If the message cannot be delivered due to a failure, the client will be notified.</p>

 <p>The client indicates its preferred message delivery mode by means of the <em>snd-settle-mode</em> and <em>rcv-settle-mode</em> fields of its <em>attach</em> frame during link establishment. Clients should use <code>mixed</code> as the <em>snd-settle-mode</em> and <code>first</code> as the <em>rcv-settle-mode</em> 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.</p>

 <h2 id="error-handling">Error Handling</h2>
-
 <p>The AMQP adapter distinguishes between two types of errors when a message is published using <em>at least once</em>:</p>
-
 <ul>
 <li>An error caused by the client side, e.g invalid message address, content-type, adapter disabled for tenant etc.</li>
 <li>An error caused by the server side, e.g no downstream consumers registered, downstream connection loss etc.</li>
 </ul>
-
 <p>For a client side error, the adapter settles the message transfer with the <em>rejected</em> 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 <em>released</em> 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.</p>

 <h2 id="amqp-command-line-client">AMQP Command-line Client</h2>
-
 <p>For purposes of demonstrating the usage of the AMQP adapter, the <strong>Hono CLI Module</strong> 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.</p>
-
 <p>The command-line client supports the following parameters (with default values):</p>
-
 <ul>
 <li><code>--spring.profiles.active=amqp-send</code>: Profile for sending telemetry data or events to Hono.</li>
 <li><code>--spring.profiles.active=amqp-command</code>: Profile for receiving and responding to command request messages.</li>

Analogously, the adapter sends an empty notification with the <em>ttd</em> header set to <code>0</code> when a device closes the link or disconnects.</p>
-
 <p>Devices 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 <em>at most once</em> (QoS 0) or <em>at least once</em> (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.</p>
-
-<p>The AMQP adapter checks the configured <a href="/hono/docs/1.4/concepts/resource-limits/">message limit</a> 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 <code>amqp:resource-limit-exceeded</code>.</p>

 <h3 id="receiving-commands">Receiving Commands</h3>
-
 <p>A device MUST use the following source address in its <em>attach</em> frame to open a link for receiving commands:</p>
-
 <ul>
 <li><code>command</code> (authenticated device)</li>
 <li><code>command</code> (authenticated gateway receiving commands for all devices it acts on behalf of)</li>
 <li><code>command/${tenant}/${device-id}</code> (unauthenticated device)</li>
 <li><code>command/${tenant}/${device-id}</code> (authenticated gateway receiving commands for a specific device it acts on behalf of)</li>
 </ul>
-
 <p>The adapter supports <em>AT LEAST ONCE</em> delivery of command messages only. A client therefore MUST use <code>unsettled</code> for the <em>snd-settle-mode</em> and <code>first</code> for the <em>rcv-settle-mode</em> fields of its <em>attach</em> frame during link establishment. All other combinations are not supported and result in the termination of the link.</p>
-
 <p>Once the link has been established, the adapter will send command messages having the following properties:</p>

-<p>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 <a href="/hono/docs/1.4/admin-guide/file-based-device-registry-config/#configuring-gateway-devices">Configuring Gateway Devices</a> for details.</p>

+<p>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 <a href="/hono/docs/1.4/admin-guide/file-based-device-registry-config/">Configuring Gateway Devices</a> for details.</p>
 <p>A gateway can open a link to receive commands for <em>all</em> devices it acts on behalf of. An authenticated gateway can also open a receiver link for commands targeted at a <em>specific</em> device.</p>
-
 <p>When processing an incoming command message, the protocol adapter will give precedence to a device-specific command consumer matching the command target device, whether it was created by a gateway or by the device itself. If multiple such consumer links have been created, by multiple gateways and/or from the device itself, the gateway or device that last created the consumer link will get the command messages.</p>
-
 <p>If no device-specific command consumer exists for a command target device, but <em>one</em> gateway, that may act on behalf of the device, has opened a generic, device-unspecific command consumer link, then the command message is sent to that gateway.</p>
-
 <p>If <em>multiple</em> gateways have opened a generic command consumer link, the protocol adapter may have to decide to which gateway a particular command message will be sent to.
 In case the command target device has already sent a telemetry, event or command response message via a gateway and if that gateway has opened a command consumer link, that gateway will be chosen. Otherwise one gateway that may act on behalf of the command target device and that has opened a command consumer link will be chosen randomly to receive the command message.</p>
-
 <h3 id="sending-a-response-to-a-command">Sending a Response to a Command</h3>
-
 <p>A device only needs to respond to commands that contain a <em>reply-to</em> address and a <em>correlation-id</em>. 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.</p>
-
 <p>The adapter supports <em>AT LEAST ONCE</em> delivery of command response messages only. A client therefore MUST set the <em>settled</em> property to <code>true</code> and the <em>rcv-settle-mode</em> property to <code>first</code> in all <em>transfer</em> frame(s) it uses for uploading command responses. All other combinations are not supported by the adapter and result in the message being rejected.</p>

 <p>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 <em>time-to-live</em> 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.</p>

+<p>The CoAP protocol adapter exposes <a href="https://tools.ietf.org/html/rfc7252">CoAP</a> based endpoints for Eclipse Hono™&rsquo;s south bound Telemetry, Event and Command &amp; Control APIs.</p>
 <div class="alert alert-notice">
     <h4 class="alert-heading"><i class="fas fa-info-circle"></i> Experimental</h4>
     <div>The CoAP adapter has not yet reached the level of maturity of the other standard adapters. In particular, the resources implemented by the adapter might
 still be subject to change.</div>

 <h2 id="device-authentication">Device Authentication</h2>
-
 <p>The CoAP adapter by default requires clients (devices or gateway components) to authenticate during connection establishment.
 The adapter (currently) only supports <a href="https://tools.ietf.org/html/rfc4279">PSK</a> as part of a DTLS handshake for that purpose.
 Additional variants mentioned in <a href="https://tools.ietf.org/html/rfc7252#section-9">Securing CoAP</a> might be added in the future.</p>
-
 <p>The adapter tries to authenticate the device using these mechanisms in the following order</p>
-
 <h3 id="psk">PSK</h3>
-
 <p>The <em>identity</em> provided in the ClientKeyExchange must have the form <em>auth-id@tenant</em>, e.g. <code>sensor1@DEFAULT_TENANT</code>.
 The adapter performs the handshake using the credentials the <a href="/hono/docs/1.4/admin-guide/common-config/#credentials-service-connection-configuration">configured Credentials service</a>
 has on record for the client. The adapter uses the Credentials API&rsquo;s <em>get</em> operation to retrieve the credentials on record
 with the <em>tenant</em> and <em>auth-id</em> provided by the device in the <em>identity</em> and <code>psk</code> as the <em>type</em> of secret as query parameters.</p>
-
 <p>The examples below refer to devices <code>4711</code> and <code>gw-1</code> of tenant <code>DEFAULT_TENANT</code> using <em>auth-ids</em> <code>sensor1</code> and <code>gw1</code> and
 corresponding secrets. The example deployment as described in the <a href="/hono/docs/1.4/deployment/">Deployment Guides</a> comes pre-configured
 with the corresponding entities in its device registry component.
 Please refer to the <a href="/hono/docs/1.4/api/credentials/#standard-credential-types">Credentials API</a> for details regarding the different
 types of secrets.</p>
-
 <p><strong>NB</strong> There is a subtle difference between the <em>device identifier</em> (<em>device-id</em>) and the <em>auth-id</em> a device uses for authentication. See <a href="/hono/docs/1.4/concepts/device-identity/">Device Identity</a> for a discussion of the concepts.</p>
-
 <h2 id="message-limits">Message Limits</h2>
-
 <p>The adapter rejects</p>
-
 <ul>
 <li>a client&rsquo;s request to upload data with status code <code>429 Too Many Requests</code> and</li>
 <li>any AMQP 1.0 message containing a command sent by a north bound application</li>
 </ul>
-
 <p>if the <a href="/hono/docs/1.4/concepts/resource-limits/">message limit</a> that has been configured for the device&rsquo;s tenant is exceeded.</p>
-
 <h2 id="coap-content-format-codes">CoAP Content Format Codes</h2>
-
 <p>CoAP doesn&rsquo;t use a textual identifier for content types. Instead numbers are used, which are maintained by the <a href="https://www.iana.org/">IANA</a>.
 The <a href="https://www.iana.org/assignments/core-parameters/core-parameters.xhtml#content-formats">IANA - CoAP Content Formats</a> page lists all

 <p>This resource can be used by <em>gateway</em> components to publish data <em>on behalf of</em> 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 <a href="https://www.sigfox.com">SigFox</a>
 or <a href="https://lora-alliance.org/">LoRa</a>. 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 URI are used to identify the device that the gateway
 publishes data for.</p>
-
 <p>The protocol adapter checks the gateway&rsquo;s authority to publish data on behalf of the device implicitly by means of retrieving a <em>registration assertion</em>
 for the device from the <a href="/hono/docs/1.4/admin-guide/common-config/#device-registration-service-connection-configuration">configured Device Registration service</a>.</p>

 <p>The CoAP adapter enables devices to receive commands that have been sent by business applications. Commands are delivered to the device by means of a response message. That means a device first has to send a request, indicating how long it will wait for the response. That request can either be a telemetry or event message, with a <code>hono-ttd</code> query parameter (<code>ttd</code> for <code>time till disconnect</code>) specifying the number of seconds the device will wait for the response. The business application can react on that message by sending a command message, targeted at the device. The CoAP adapter will then send the command message as part of the response message to the device.</p>

-<p>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.

+<p>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 <a href="/hono/docs/1.4/admin-guide/file-based-device-registry-config/">Configuring Gateway Devices</a> for details.</p>
 <p>A gateway can send a request with the <code>hono-ttd</code> query parameter on the <code>/event</code> or <code>/telemetry</code> URI, indicating its readiness to receive a command for <em>any</em> device it acts on behalf of. Note that in this case, the business application will be notified with the gateway id in the <code>device_id</code> property of the downstream message.</p>
-
 <p>An authenticated gateway can also indicate its readiness to receive a command targeted at a <em>specific</em> device. For that, the <code>/event/${tenantId}/${deviceId}</code> or <code>/telemetry/${tenantId}/${deviceId}</code> URI is to be used, containing the id of the device to receive a command for. The business application will receive a notification with that device id.</p>
-
 <p>If there are multiple concurrent requests with a <code>hono-ttd</code> query parameter, sent by the command target device and/or one or more of its potential gateways, the CoAP adapter will choose the device or gateway to send the command to as follows:</p>
-
 <ul>
 <li>A request done by the command target device or by a gateway specifically done for that device, has precedence. If there are multiple, concurrent such requests, the last one will get the command message (if received) in its response. Note that the other requests won&rsquo;t be answered with a command message in their response event if the business application sent multiple command messages. That means commands for a single device can only be requested sequentially, not in parallel.</li>
 <li>If the above doesn&rsquo;t apply, a single <code>hono-ttd</code> request on the <code>/event</code> or <code>/telemetry</code> URI, sent by a gateway that the command target device is configured for, will get the command message in its response.</li>
 <li>If there are multiple, concurrent such requests by different gateways, all configured for the command target device, the request by the gateway will be chosen, through which the target device has last sent a telemetry or event message. If the target device hasn&rsquo;t sent a message yet and it is thereby unknown via which gateway the device communicates, then one of the requests will be chosen randomly to set the command in its response.</li>

 <p>The adapter also considers <em>defaults</em> registered for the device at either the <a href="/hono/docs/1.4/api/tenant/#tenant-information-format">tenant</a> or the <a href="/hono/docs/1.4/api/device-registration/#assert-device-registration">device level</a>. The values of the default properties are determined as follows:</p>
-
 <ol>
 <li>If the message already contains a non-empty property of the same name, the value if unchanged.</li>
 <li>Otherwise, if a default property of the same name is defined in the device&rsquo;s registration information, that value is used.</li>
 <li>Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.</li>
 </ol>
-
 <p>Note that of the standard AMQP 1.0 message properties only the <em>content-type</em> and <em>ttl</em> can be set this way to a default value.</p>
-
 <h3 id="event-message-time-to-live">Event Message Time-to-live</h3>
-
 <p>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 <em>time-to-live</em> 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.</p>
-
 <p>In order to support environments where the AMQP Messaging Network cannot be configured accordingly, the protocol adapter supports setting a
 downstream event message&rsquo;s <em>ttl</em> property based on the <em>hono-ttl</em> property set as a query parameter in the event requests by the devices.
-Also the default <em>ttl</em> and <em>max-ttl</em> values can be configured for a tenant/device as described in the <a href="/hono/docs/1.4/api/tenant/#resource-limits-configuration-format">Tenant API</a>.</p>

+Also the default <em>ttl</em> and <em>max-ttl</em> values can be configured for a tenant/device as described in the [Tenant API]

+<p>The HTTP protocol adapter exposes HTTP based endpoints for Eclipse Hono™&rsquo;s south bound Telemetry, Event and Command &amp; Control APIs.</p>
 <h2 id="device-authentication">Device Authentication</h2>
-
 <p>The HTTP adapter by default requires clients (devices or gateway components) to authenticate during connection establishment. The adapter supports both the <a href="https://tools.ietf.org/html/rfc7617">Basic HTTP authentication scheme</a> as well as client certificate based authentication as part of a TLS handshake for that purpose.</p>
-
 <p>The adapter tries to authenticate the device using these mechanisms in the following order</p>
-
 <h3 id="client-certificate">Client Certificate</h3>
-
 <p>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 <em>issuer DN</em> contained in the certificate. In order for the lookup to succeed, the tenant&rsquo;s trust anchor needs to be configured by means of <a href="/hono/docs/1.4/api/tenant/#tenant-information-format">registering the trusted certificate authority</a>. The device&rsquo;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&rsquo;s <em>get</em> operation with the client certificate&rsquo;s <em>subject DN</em> as the <em>auth-id</em> and <code>x509-cert</code> as the <em>type</em> of secret as query parameters.</p>
-
-<p><strong>NB</strong> The HTTP adapter needs to be <a href="/hono/docs/1.4/admin-guide/secure_communication/#http-adapter">configured for TLS</a> in order to support this mechanism.</p>

 <h3 id="http-basic-auth">HTTP Basic Auth</h3>
-
-<p>The <em>username</em> provided in the header must have the form <em>auth-id@tenant</em>, e.g. <code>sensor1@DEFAULT_TENANT</code>. The adapter verifies the credentials provided by the client against the credentials that the <a href="/hono/docs/1.4/admin-guide/common-config/#credentials-service-connection-configuration">configured Credentials service</a> has on record for the client. The adapter uses the Credentials API&rsquo;s <em>get</em> operation to retrieve the credentials on record with the <em>tenant</em> and <em>auth-id</em> provided by the device in the <em>username</em> and <code>hashed-password</code> as the <em>type</em> of secret as query parameters.</p>

 <p>The examples below refer to devices <code>4711</code> and <code>gw-1</code> of tenant <code>DEFAULT_TENANT</code> using <em>auth-ids</em> <code>sensor1</code> and <code>gw1</code> and corresponding passwords. The example deployment as described in the <a href="/hono/docs/1.4/deployment/">Deployment Guides</a> comes pre-configured with the corresponding entities in its device registry component.
 Please refer to the <a href="/hono/docs/1.4/api/credentials/#standard-credential-types">Credentials API</a> for details regarding the different types of secrets.</p>
-
 <p><strong>NB</strong> There is a subtle difference between the <em>device identifier</em> (<em>device-id</em>) and the <em>auth-id</em> a device uses for authentication. See <a href="/hono/docs/1.4/concepts/device-identity/">Device Identity</a> for a discussion of the concepts.</p>

 <p>This resource can be used by <em>gateway</em> components to publish data <em>on behalf of</em> 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 <a href="https://www.sigfox.com">SigFox</a> or <a href="https://lora-alliance.org/">LoRa</a>. 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 URI are used to identify the device that the gateway publishes data for.</p>
-
 <p>The protocol adapter checks the gateway&rsquo;s authority to publish data on behalf of the device implicitly by means of retrieving a <em>registration assertion</em> for the device from the <a href="/hono/docs/1.4/admin-guide/common-config/#device-registration-service-connection-configuration">configured Device Registration service</a>.</p>

 <p>This resource can be used by <em>gateway</em> components to publish data <em>on behalf of</em> 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 <a href="https://www.sigfox.com">SigFox</a> or <a href="https://lora-alliance.org/">LoRa</a>. 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 URI are used to identify the device that the gateway publishes data for.</p>
-
 <p>The protocol adapter checks the gateway&rsquo;s authority to publish data on behalf of the device implicitly by means of retrieving a <em>registration assertion</em> for the device from the <a href="/hono/docs/1.4/admin-guide/common-config/#device-registration-service-connection-configuration">configured Device Registration service</a>.</p>

 <p>The HTTP adapter enables devices to receive commands that have been sent by business applications. Commands are delivered to the device by means of an HTTP response message. That means a device first has to send a request, indicating how long it will wait for the response. That request can either be a telemetry or event message, with a <code>hono-ttd</code> header or query parameter (<code>ttd</code> for <code>time till disconnect</code>) specifying the number of seconds the device will wait for the response. The business application can react on that message by sending a command message, targeted at the device. The HTTP adapter will then send the command message as part of the HTTP response message with status <code>200</code> (OK) to the device. If the HTTP adapter receives no command message in the given time period, a <code>202</code> (Accepted) response will be sent to the device (provided the request was valid).</p>

-<p>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 <a href="/hono/docs/1.4/admin-guide/file-based-device-registry-config/#configuring-gateway-devices">Configuring Gateway Devices</a> for details.</p>

+<p>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 <a href="/hono/docs/1.4/admin-guide/file-based-device-registry-config/">Configuring Gateway Devices</a> for details.</p>
 <p>A gateway can send a request with the <code>hono-ttd</code> header or query parameter on the <code>/event</code> or <code>/telemetry</code> URI, indicating its readiness to receive a command for <em>any</em> device it acts on behalf of. Note that in this case, the business application will be notified with the gateway id in the <code>device_id</code> property of the downstream message.</p>
-
 <p>An authenticated gateway can also indicate its readiness to receive a command targeted at a <em>specific</em> device. For that, the <code>/event/${tenantId}/${deviceId}</code> or <code>/telemetry/${tenantId}/${deviceId}</code> URI is to be used, containing the id of the device to receive a command for. The business application will receive a notification with that device id.</p>
-
 <p>If there are multiple concurrent requests with a <code>hono-ttd</code> header or query parameter, sent by the command target device and/or one or more of its potential gateways, the HTTP adapter will choose the device or gateway to send the command to as follows:</p>
-
 <ul>
 <li>A request done by the command target device or by a gateway specifically done for that device, has precedence. If there are multiple, concurrent such requests, the last one will get the command message (if received) in its response. Note that the other requests won&rsquo;t be answered with a command message in their response event if the business application sent multiple command messages. That means commands for a single device can only be requested sequentially, not in parallel.</li>
 <li>If the above doesn&rsquo;t apply, a single <code>hono-ttd</code> request on the <code>/event</code> or <code>/telemetry</code> URI, sent by a gateway that the command target device is configured for, will get the command message in its response.</li>
 <li>If there are multiple, concurrent such requests by different gateways, all configured for the command target device, the request by the gateway will be chosen, through which the target device has last sent a telemetry or event message. If the target device hasn&rsquo;t sent a message yet and it is thereby unknown via which gateway the device communicates, then one of the requests will be chosen randomly to set the command in its response.</li>

 <p>This resource can be used by <em>gateway</em> components to send the response to a command <em>on behalf of</em> 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 <a href="https://www.sigfox.com">SigFox</a> or <a href="https://lora-alliance.org/">LoRa</a>. 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 URI are used to identify the device that the gateway publishes data for.</p>
-
 <p>The protocol adapter checks the gateway&rsquo;s authority to send responses to a command on behalf of the device implicitly by means of retrieving a <em>registration assertion</em> for the device from the <a href="/hono/docs/1.4/admin-guide/common-config/#device-registration-service-connection-configuration">configured Device Registration service</a>.</p>

 <p>The adapter also considers <em>defaults</em> registered for the device at either the <a href="/hono/docs/1.4/api/tenant/#tenant-information-format">tenant</a> or the <a href="/hono/docs/1.4/api/device-registration/#assert-device-registration">device level</a>. The values of the default properties are determined as follows:</p>
-
 <ol>
 <li>If the message already contains a non-empty property of the same name, the value if unchanged.</li>
 <li>Otherwise, if a default property of the same name is defined in the device&rsquo;s registration information, that value is used.</li>
 <li>Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.</li>
 </ol>
-
 <p>Note that of the standard AMQP 1.0 message properties only the <em>content-type</em> and <em>ttl</em> can be set this way to a default value.</p>
-
 <h3 id="event-message-time-to-live">Event Message Time-to-live</h3>
-
 <p>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 <em>time-to-live</em> 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.</p>
-
 <p>In order to support environments where the AMQP Messaging Network cannot be configured accordingly, the protocol adapter supports setting a
 downstream event message&rsquo;s <em>ttl</em> property based on the <em>hono-ttl</em> property set as a header or a query parameter in the event requests by the devices.
-Also the default <em>ttl</em> and <em>max-ttl</em> values can be configured for a tenant/device as described in the <a href="/hono/docs/1.4/api/tenant/#resource-limits-configuration-format">Tenant API</a>.</p>

+<p>Eclipse Hono™ comes with an <a href="https://jmeter.apache.org">Apache JMeter</a> plugin which provides <em>samplers</em> that can be used in JMeter test plans to send and receive telemetry/event data.</p>
 <p>The plugin provides a <em>Hono Receiver Sampler</em> which can be used together with JMeter&rsquo;s standard <em>HTTP Sampler</em> and XMeter&rsquo;s <a href="https://github.com/emqx/mqtt-jmeter">JMeter plugin for MQTT</a> to play the roles of a downstream application (consumer) and devices uploading data to the HTTP and MQTT protocol adapters. The diagram below illustrates how the components are related to each other.</p>

 <li>Copy the plugin jar file <code>&lt;hono-installation&gt;/jmeter/target/plugin/hono-jmeter-&lt;version&gt;-jar-with-dependencies.jar</code> to the  <code>&lt;jmeter-installation&gt;/lib/ext</code> folder.</li>

 <h2 id="example-test-plans">Example Test Plans</h2>
-
 <p>The <code>&lt;hono-installation&gt;/jmeter/src/jmeter</code> folder contains several JMeter test plans which you can use as a basis for your own tests. All test plans can be run against Hono&rsquo;s <a href="/hono/docs/1.4/deployment/">example deployment</a>.</p>
-
 <ol>
-<li><code>http_messaging_throughput_test.jmx</code> runs a set of HTTP clients and AMQP 1.0 consumers for a given period of time. The senders publish data to Hono&rsquo; HTTP adapter while the consumers receive messages from the AMQP 1.0 Messaging Network (in case of the example installation this is the Qpid Dispatch Router). The test plan measures the number of messages that are sent/received during the test execution.</li>
-<li><code>mqtt_messaging_throughput_test.jmx</code> runs a set of MQTT clients and AMQP 1.0 consumers for a given period of time. The clients publish data to Hono&rsquo; MQTT adapter while the consumers receive messages from the AMQP 1.0 Messaging Network (in case of the example installation this is the Qpid Dispatch Router). The test plan measures the number of messages that are sent/received during the test execution. To use this plan you also need to add the <a href="https://github.com/emqx/mqtt-jmeter">JMeter plugin for MQTT</a> to your JMeter plugin path.</li>

 <li><code>amqp_messaging_throughput_test.jmx</code> runs a set of AMQP 1.0 senders and consumers for a given period of time. The senders publish data to the AMQP 1.0 Messaging Network directly while the consumers receive messages from the AMQP 1.0 Messaging Network (in case of the example installation this is the Qpid Dispatch Router). The test plan measures the number of messages that are sent/received during the test execution.<br>
 The sender can be configured to wait for <em>n active receivers</em> (from this test plan and JMeter instance) which can be used to make sure, that the receivers consuming from the corresponding address (e.g. <code>telemetry/DEFAULT_TENANT</code>) are up and running before the senders begin to publish messages.</li>
 </ol>
-
 <p>It is recommended to run the test plans in <em>non-gui mode</em> as illustrated by the example shell scripts that are contained in the <code>&lt;hono-installation&gt;/jmeter/src/jmeter</code> folder. You may need to adapt some of the properties to reflect your concrete setup, e.g. the path to the trust store, host names, ports etc.</p>

 <p>Please refer to the <a href="http://eclipse.github.io/kura/config/cloud-services.html">Eclipse Kura documentation</a> on how to configure the
 gateway&rsquo;s cloud service connection accordingly. It is important to set the gateway&rsquo;s <em>topic.context.account-name</em> to the ID of the
 Hono tenant that the gateway has been registered with whereas the gateway&rsquo;s <em>client-id</em> needs to be set to the corresponding Hono
 device ID. The <em>auth-id</em> used as part of the gateway&rsquo;s <em>username</em> property needs to match the authentication identifier of a set of
 credentials registered for the device ID in Hono&rsquo;s Credentials service. In other words, the credentials configured on the gateway
 need to belong to the corresponding device ID.</p>

 <p><strong>NB</strong> There is a subtle difference between the <em>device identifier</em> (<em>device-id</em>) and the <em>auth-id</em> a device uses for authentication.

 <p>The MongoDB based Device Registry component provides implementations of Hono&rsquo;s <a href="/hono/docs/1.4/api/tenant/">Tenant API</a>, <a href="/hono/docs/1.4/api/device-registration/">Device Registration API</a> and <a href="/hono/docs/1.4/api/credentials/">Credentials API</a>. As such it exposes AMQP 1.0 based endpoints for retrieving the relevant information. Protocol adapters use these APIs to determine a device&rsquo;s registration status, e.g. if it is enabled and if it is registered with a particular tenant, and to authenticate a device before accepting any data for processing from it.</p>
-
 <p>In addition to the above APIs, this Device Registry also exposes HTTP endpoints for managing the contents of the Device Registry according to the <a href="/hono/docs/1.4/api/management/">Device Registry Management API</a>. It uses a MongoDB database to persist the data. The credentials, device and tenant information are stored in separate collections in a MongoDB database. For more information on how to configure the MongoDB based device registry, see <a href="/hono/docs/1.4/admin-guide/mongodb-device-registry-config/">MongoDB based Device Registry configuration</a>.</p>
-
 <h2 id="authentication">Authentication</h2>
-
-<p>This Device Registry secures its HTTP Endpoints using basic authentication mechanism. Thereby the clients connecting to the MongoDB based Device Registry are required to authenticate. For more information on how to enable the authentication and configure it, please refer to the <code>hono.registry.http.authenticationRequired</code> property in the <a href="/hono/docs/1.4/admin-guide/mongodb-device-registry-config/#service-configuration">MongoDB based Device Registry configuration</a>.</p>

 <p>The MQTT adapter enables devices to receive commands that have been sent by business applications by means of sending an MQTT <em>SUBSCRIBE</em> packet containing a device specific <em>topic filter</em> 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 <em>SUBACK</em> packet. The SUBACK packet will contain <em>Success - QoS 0</em> (<code>0x00</code>) or <em>Success - QoS 1</em> (<code>0x01</code>) for a command topic filter indicating QoS 0 or 1 and will contain the <em>Failure</em> (<code>0x80</code>) value for all other filters. When a device no longer wants to receive commands anymore, it can send an MQTT <em>UNSUBSCRIBE</em> packet to the adapter, including the same topic filter that has been used to subscribe.</p>

 <p>When a device has successfully subscribed, the adapter sends an <a href="/hono/docs/1.4/api/event/#empty-notification">empty notification</a> on behalf of the device to the downstream AMQP 1.0 Messaging Network with the <em>ttd</em> header set to <code>-1</code>, indicating that the device will be ready to receive commands until further notice. Analogously, the adapter sends an empty notification with the <em>ttd</em> header set to <code>0</code> when a device unsubscribes from commands.</p>
-
 <p>Commands can be sent following a <em>request/response</em> pattern or being <em>one-way</em>.</p>
-
 <p>For <em>Request/Response</em> commands, devices send their responses to commands by means of sending an MQTT <em>PUBLISH</em> 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.</p>
-
-<p>The MQTT adapter checks the configured <a href="/hono/docs/1.4/concepts/resource-limits/">message limit</a> 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 <code>amqp:resource-limit-exceeded</code>. And for the incoming command responses from devices, the Adapter rejects the message and closes the connection to the client.</p>

 <p>The following sections define the topic filters/names to use for subscribing to and responding to commands. The following <em>shorthand</em> versions of topic path segments are supported:</p>
-
 <ul>
 <li><code>c</code> instead of <code>command</code></li>
 <li><code>q</code> instead of <code>req</code></li>
 <li><code>s</code> instead of <code>res</code></li>
 </ul>
-
 <p>The following variables are used:</p>
-
 <ul>
 <li><code>${command}</code> : An arbitrary string that indicates the command to execute, e.g. <code>setBrightness</code>. The command is provided by the application that sends the command.</li>
 <li><code>${req-id}</code> (only for <em>Request/Response</em> commands) : The unique identifier of the command execution request. The identifier 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.</li>
 <li><code>${status}</code> : The HTTP status code indicating the outcome of executing the command. This status code is passed on to the application in the AMQP message&rsquo;s <em>status</em> application property.</li>
 </ul>

 <p>When processing an incoming command message, the protocol adapter will give precedence to a device-specific command subscription matching the command target device, whether the subscription comes from a gateway or the device itself. If there are multiple such subscriptions from multiple gateways and/or from the device itself, the subscription initiated last will get the command messages.</p>
-
 <p>If no device-specific command subscription exists for a command target device, but <em>one</em> gateway, that may act on behalf of the device, has subscribed to commands for all its devices, then the command message is sent to that gateway.</p>
-
 <p>If <em>multiple</em> gateways have initiated such generic subscriptions, the protocol adapter may have to decide to which gateway a particular command message will be sent to.
 In case the command target device has already sent a telemetry, event or command response message via a gateway and if that gateway has created such a command subscription, that gateway will be chosen. Otherwise one gateway that may act on behalf of the command target device and that has an open subscription will be chosen randomly to receive the command message.</p>

 <p>A subscription to commands for all devices that a gateway acts on behalf of looks like this:</p>

 <p>This protocol adapter supports transformation of messages that have been uploaded by devices before they get forwarded to downstream consumers.</p>
-
 <div class="alert alert-notice">
     <h4 class="alert-heading"><i class="fas fa-info-circle"></i> Experimental</h4>
     <div>This is an experimental feature. The names of the configuration properties, potential values and the overall functionality are therefore
 subject to change without prior notice.</div>
 </div>
-
 <p>This feature is useful in scenarios where devices are connected to the adapter via a gateway but the gateway is not able to include
 the device ID in the topic that the gateway publishes data to. The gateway will use the plain <code>telemetry</code> or <code>event</code> topics in this case.
 The message payload will usually contain the identifier of the device that the data originates from.</p>
-
 <p>The same functionality can also be used to transform the payload of messages uploaded by a device. This can be used for example to
 transform binary encoded data into a JSON document which can be consumed more easily by downstream consumers.</p>
-
-<p>The mechanism works as follows:
-1. A client uploads a message to the MQTT adapter.
-1. The adapter invokes the Device Registration service&rsquo;s <em>assert Registration</em> operation using either
-   the authenticated device&rsquo;s identifier, if the topic does not contain a device ID, or the device ID from the
-   topic.
-1. If the assertion succeeds, the adapter creates the downstream message using the original message&rsquo;s payload and
-   the asserted device ID as the origin device.
-1. If the response payload contains a value for the <em>mapper</em> property, the adapter tries to find a <em>mapper endpoint</em> configuration
-   for the given value. If a mapper endpoint with a matching name has been configured for the adapter,
-   1. the adapter sends an HTTP request to the endpoint which contains the original message&rsquo;s payload in the request body.
-   1. If the response body is not empty, it is used as the downstream message&rsquo;s payload.
-   1. If the response contains a <em>device_id</em> header and its value is different from the original device ID, then the adapter
-      invokes the <em>assert Registration</em> operation again, this time using the mapped device ID instead of the original device ID.
-      If the assertion succeeds, the adapter uses the asserted (mapped) device ID for the downstream message.
-1. The adapter forwards the downstream message.</p>
-
+<p>The mechanism works as follows:</p>
+<ol>
+<li>A client uploads a message to the MQTT adapter.</li>
+<li>The adapter invokes the Device Registration service&rsquo;s <em>assert Registration</em> operation using either

 <li>Otherwise, if a default property of the same name is defined for the tenant that the device belongs to, that value is used.</li>
 </ol>
-
 <p>Note that of the standard AMQP 1.0 message properties only the <em>content-type</em> and <em>ttl</em> can be set this way to a default value.</p>
-
 <h3 id="event-message-time-to-live">Event Message Time-to-live</h3>
-
 <p>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 <em>time-to-live</em> 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.</p>
-
 <p>In order to support environments where the AMQP Messaging Network cannot be configured accordingly, the MQTT protocol adapter supports setting a
 downstream event message&rsquo;s <em>ttl</em> property based on the <em>hono-ttl</em> property set as <em>property-bag</em> at the end of the event topic.
-Also the default <em>ttl</em> and <em>max-ttl</em> values can be configured for a tenant/device as described in the <a href="/hono/docs/1.4/api/tenant/#resource-limits-configuration-format">Tenant API</a>.</p>
-
+Also the default <em>ttl</em> and <em>max-ttl</em> values can be configured for a tenant/device as described in the [Tenant API]
+(/hono/docs/1.4/api/tenant/#resource-limits-configuration-format).</p>
 <h2 id="tenant-specific-configuration">Tenant specific Configuration</h2>
-
 <p>The adapter uses the <a href="/hono/docs/1.4/api/tenant/#get-tenant-information">Tenant API</a> to retrieve <em>tenant specific configuration</em> for adapter type <code>hono-mqtt</code>.

 be subject to change without warning.</div>

 <h2 id="pre-requisites">Pre-requisites</h2>
-
 <p>This Sigfox adapter only connects to the Sigfox backend system
 (<code>backend.sigfox.com</code>). It does not allow direct access to Sigfox devices.</p>
-
 <p>So you need to set up your Sigfox devices on <code>backend.sigfox.com</code> and then
 configure the callbacks connect to your installation of Hono.</p>
-
 <h2 id="devices-and-credentials">Devices and credentials</h2>
-
 <p>In a nutshell, the Sigfox adapter requires a single <em>device</em> identity, acting
 as a gateway device. This identity will be used to connect to Hono. All devices
 registered with Sigfox (the actual Sigfox devices), will be registered in Hono
 to allow this first identity as their gateway device.</p>
