Subject: [OASIS Issue Tracker] (MQTT-591) DISCONNECT retainRegistrations flag for sleep
[ https://issues.oasis-open.org/browse/MQTT-591?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=82215#comment-82215 ] Davide Lenzarini commented on MQTT-591: --------------------------------------- [~simon.johnson1]ÂI think the RetainRegistrations flag should be considered only if the session expiry interval is defined, right? > DISCONNECT retainRegistrations flag for sleep > --------------------------------------------- > > Key: MQTT-591 > URL: https://issues.oasis-open.org/browse/MQTT-591 > Project: OASIS Message Queuing Telemetry Transport (MQTT) TC > Issue Type: Improvement > Components: MQTT-SN > Reporter: Simon Johnson [X] > Assignee: Simon Johnson [X] > Priority: Major > > Registrations being removed across SLEEPING states has been raised as a concern due to the overhead of the need to reestablish using REGISTER packets during the AWAKE state. > Both cases are valid, since some devices want to truly SLEEP and will clear ephemeral data during this phase. Therefore we should add optionality to this function using a retain registrations, sent by the client during the DISCONNECT session-expiry-interval packet. -- This message was sent by Atlassian Jira (v8.3.3#803004)
