Ian Craggs updated MQTT-539:
----------------------------
Component/s: MQTT-SN
> TopicId in PUBACK is superfluous
> --------------------------------
>
> Key: MQTT-539
> URL: https://issues.oasis-open.org/browse/MQTT-539
> Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
> Issue Type: Improvement
> Components: MQTT-SN
> Affects Versions: mqtt-sn-1.2
> Reporter: Ian Craggs
> Priority: Major
>
> Via Tomoaki Yamaguchi. "The topicId in the PUBACK packet makes the gateway implementation complicated. The msgId in PUBACK is enough for the client to handle the response."
> This also makes the PUBACK different to the PUBREC, PUBREL and PUBCOMP. Perhaps this was for the purpose of reporting errors as these three acks also lack a return code field (which will be dealt with in another issue).
