Unable to access to connect response code (IDFGH-1444) #94

Closed GiviMAD closed 4 years ago

GiviMAD commented 5 years ago

With the current implementation I can't access to the initial connection response code there fore I'm not able to detect a connection refused error like bad username from my code. Am I missing something? Thanks in advance

Yes, you are correct. There's no means to programmatically check error codes. We can emit an event with id=MQTT_EVENT_ERROR and provide (connection) error code as an appropriate context data (that's actually a purpose of this event, but in current version it's never fired).

Thanks for raising this issue, will look into it.

Is there a way to get the error code?

david-cermak commented 5 years ago

@InfiniteYuan1 sorry for the delay. The code has just been pushed to IDF master, see the usage in ssl example here https://github.com/espressif/esp-idf/blob/master/examples/protocols/mqtt/ssl/main/app_main.c#L82-L86. (hasn't been merged to MQTT yet, once it's done this issue will be closed)
