Subject: [OASIS Issue Tracker] (MQTT-599) In ASLEEP state also a PUBLISH-1 should trigger the sending of the pending messages on the subscribed topics
[ https://issues.oasis-open.org/browse/MQTT-599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=82467#comment-82467 ] Davide Lenzarini commented on MQTT-599: --------------------------------------- [~thesii]Thanks for your explanations during the workshop today! On the basis of WD25 chapter 3.5.4 the keep alive timer for a client can be reset by the reception of PUBLISH-1 coming from the same device. When a client sends a PUBLISH-1, it may decide to sleep immediately after and so start sending queued messages + PINGRESP can be useless. For this reason I think we can close this ticket.
