Hi,
How many retransmissions the Cinterion modules does if he doesn't receive the confirmation of QoS 2.
The module will retransmit until he receive the confirmation, or there is a limit number of tries?
Hello,
In general it should retransmit the message until it gets PUBREC packet from the receiver. Honestly I don't know if there may be any fixed maximum value but I can imagine that it can depend on the free resources or something like that. What module is it (ATI1 reply)? I can try to find out something.
BR,
