Davide Lenzarini commented on MQTT-598:
---------------------------------------

[~andysc]ÂThe scenario that I have in mind is the following:
 # A client CONNECT to a gateway (client enrollment) with a very long session expiry interval
 # The client subscribe to a certain topic to receive pending messages as soon as it sends a publish-1 message to a certain (also different) topic
 # The client DISCONNECTÂwith a very long session expiry interval
 # After some time the client send a PUBLISH-1 message and would like to receive (like with the PINGREQ when in ASLEEP state) all pending messages on the topic it has subscribed to but only if their QoS is -1

Does it make sense to you?

> A client should be able to subscribe to a topic with QoS-1, this way it would be possible for it to receive Application Messages also when in status âasleepâ immediately after it sends a Publish QoS-1.Â
