             Summary: Allow 0-length client id
                 Key: MQTT-542
                 URL: https://issues.oasis-open.org/browse/MQTT-542
             Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
          Issue Type: Improvement
          Components: MQTT-SN
    Affects Versions: MQTT-SN-1.2
            Reporter: Ian Craggs


The *clientid variable length field* is allowed to be 0-length in both MQTT 3.1.1 and 5.0, indicating that the server should assign a clientid itself. If we do allow this behaviour in MQTT-SN I think itâs important that that clientid is returned to the client, as it is in MQTT 5.0. This could be done by including the server assigned clientid in the MQTT-SN CONNACK packet, which currently has no variable length field.
