Which port are you using? STM32 or ESP32?

This is resolved. Thank you.

I am however, having issues understanding the network library/class

On Linux after I enter the REPL command prompt and enter:

import network
lan = network.LAN()

The command prompt closes and goes back to the terminal. Not sure why this happens.
Also, where could I find more information about this. I can find documentation anywhere

Thanks
