Subject: [OASIS Issue Tracker] (MQTT-539) TopicId in PUBACK is superfluous
[ https://issues.oasis-open.org/browse/MQTT-539?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] 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). -- This message was sent by Atlassian Jira (v8.3.3#803004)
