Return MQTT Error reason #581

Closed tyeth closed 1 month ago

tyeth commented 1 month ago

We have had a few situations, including currently #579 , where a user cannot connect to IO MQTT broker, but there wifi is connected.

This feature will print the returned error number, and error string (there is a connectionErrorString helper)

PR in #580
