PUBLISH & SUBSCRIBE in the same program

Post by masoldier » Tue Jun 05, 2018 6:22 am

Hey community, hope everyone is creating something awesome with our beloved MicroPython+NodeMCU :D

Let's cut to the chase - I am successfully able to PUBLISH and SUBSCRIBE to messages on Adafruit and it just works. The real problem is that when I try to merge these two-independent programs into one, everything gets destroyed.

1. The broker gets stuck and just sits there like a fossil.
2. Hardly ever my NodeMCU publishes or responds to a subscribed message and that too in multiple resets of the board.

Please help me out here. I am in PAIN :!:

Maybe you can tell us a little more about your broker and your client program

coincidentally, I just updated my github MQTT examples to support the lastest MicroPython and CircuitPython releases. I included an example on using Publish and Subscribe in the same file. Check out the file pubAndSub.py. It might have what you are looking for.
