“This should be straightforward,” I thought, “I’ll just install umqtt.simple in the Thonny package manager.”
— turns out… that doesn’t work. I can sort-of get umqtt.simple installed by copying simple.py from micropython-lib into /lib/umqtt, but then it’s asking for usocket.
Has anyone managed to get a Pico with a Wireless pack talking over MQTT? Did you take notes? I’m at a bit of a loss to know where to start.
I’m having the same problem. I have a Pico W microPython script to read from a BME280 sensor (on the Breakout Garden). It works fine locally, but I want to connect via MQTT. I tried installing mqtt.simple via theThonny package manager, but it just fails. Nobody seems to respond.
Have you tried this one
And use this build of micropython

This was the original guide a followed many months ago that worked for me.
Thanks for these suggestions. I agree that either of them should work, and I can confirm that the first one genuinely does. I haven’t yet tried migrating my MQTT code back to the umqtt.simple library package, which I’d completely forgotten about (durr!).
For anyone stumbling across this thread, however: MQTT is now straightforward on a Pico W. With the older Pico Wireless Pack which was the subject of this thread (which added wifi to a bare Pico) things won’t be as straightforward. If you have one of those, frankly… give up and replace it with a Pico W, it’s just not worth the hassle to do non-standard networking.
