AckedMessage of Qos 1 and 2.

[sayid hun]

I'm developing a broker with netty,and have a confusion.

A message which should be acked such as PUBLISH was sent to client/server without ack message a few seconds later.should the server/client send the original message with a dup flag

again.

as far as I know,moquette(broker) and mqtt-client(fusrsource)  didn't re-send the un-acked message.

Hi Sayid,

A client/server is not required to resend an unacknowledged message except for when a non-clean session client reconnects and there were unacknowledged messages when it disconnected.

Hope that helps,

Nick
