Unconnected MQTT publish fails silently about micropython-lib HOT 4 OPEN

In fact, its a bit opaque to me how robust achieves its reconnection functionality.

It doesn't have to be like that - code is at every MicroPython user's fingertips and simple to understand: https://github.com/micropython/micropython-lib/blob/master/umqtt.robust/umqtt/robust.py#L29

I'll look into the main topic of this issue when time permits.

Sorry, me being unclear. Looking at the code, I wonder how robust would reconnect in a situation other than a publish failure, ie: loss of connection with subscribe only?

from micropython-lib.

Subscription requires running event loop (wait_msg() function). It's also protected in a similar fashion to publish(): https://github.com/micropython/micropython-lib/blob/master/umqtt.robust/umqtt/robust.py#L37

Thanks for the explanation, obvious now you say.
