| The MQTT protocol module was written initially with an external codec (see http://git.eclipse.org/c/titan/titan.ProtocolModules.MQTT.git/) |
| |
| The reason for this was that the variable length encoding of remLength cannot be directly handled by RAW alone; some external assistance is needed; |
| A new protocol module has been written (based on the RAW codec), which can handle encoding directions. But for the decoding the external codec should be used. |
| |
| To enable more throughout fuzzing (negative testing) the TTCN-3 types were extended with fields that stores the length of fields of the length of payload, based on the MQTT standard. |
| |
| The RAW encoder cannot compute correctly the remLength field, but calling the f_adjustLength function on the result of the RAW encoding will produce the correct remLength and the correct message to be sent. |
