I am sending and receiving MQTT messages. My problem is that after normally working it could be that one ACK is not been sent out to the broker which prevents him to send anymore messages to my board.
I recognized that by watching the packets on the bus with wireshark and also some debug prints. My app is running it could be for hours. I can send and receive messages for a long time. But on any circumstances one ACK is not been sent to the network and stalls the whole communication with the broker.
What about watching the tx interrupt coming from the eth. Any more ideas where to debug this in more detail.
Thanks in advance
