QOS 1/2 fail after 254 messages
Hi Once my ESP module has sent 254 messages in qos mode 1 or 2 it will return with a fail permanently. My eMqtt server console displays "[error] Session arduinoClient AwaitingRel Timout!"
Once reset, everything is fine again. I use the one of the default examples to publish messages at an interval of between 20ms - 2sec. Same result every time. What can be the problem?
