Do not send messages for a long time mqtt automatically disconnects #295

Closed 0716gzs closed 4 months ago

When I use aiomqtt to connect to mqtt after an hour without sending mqtt messages, the following error occurs: aiomqtt. exceptions.MqttCodeError: [code:16] Client or broker did not communicate in the keepalive interval.

However, I see the underlying default keepalive is 60. What is the reason for this

This exception is raised in the underlying paho-mqtt library and aiomqtt only propagates it in a custom exception. On first glance, we probably can't solve this inside aiomqtt, could you check the paho-mqtt project, maybe there's some info on this over there? This issue and this one seem related (code 16) for example.

I'll tentatively close this as there have been no further responses. If it is still a problem, please feel free to reopen! 🙂
