Use

• Install packages ...

import network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect("Wi-Fi AP", "PASSWORD")

import upip
upip.install('umqtt.simple')
upip.install('umqtt.robust')

for later versions of MicroPython, you should use mip instead...

import network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect("Wi-Fi AP", "PASSWORD")

import mip
mip.install('umqtt.simple')
mip.install('umqtt.robust')

• Upload files onto PICO, adjust params (such as Wi-Fi Credentials // pins // etc ), deploy to your PICO W
