Receiving Memory Allocation Error in Import [message #1858526]

I used the Thonny Package Installer to install PAHO MQTT. On a RPI P400 it runs fine. I get a memory allocation error on the PICO W. If I comment out the IMPORT, the program runs till it gets to an error calling MQTT.

Is the PAHO MQTT too large to run on PICO W?

Yes, for a Pico W you're running MicroPython, which is not able to run Paho. You should look at a MicroPython MQTT library instead. There are some really good options listed via awesome-micropython. I regularly use micropython-mqtt
