[ESP32 Micropython]Total noob here, I don't understand why this while loop won't run.

Not that I've used the libraries that you are using, but would while not station.scan(): be better? That way (in theory, least ways) you're testing for 'truthfulness'. Also, do you not have to update station.scan() in the while: loop? If not, how will any change in state be detected?

I now have this code

# wifi_test.py
import network
import time

# Create a station object to store our connection
wifi = network.WLAN(network.STA_IF)
wifi.active(True)

available_wifi_networks = wifi.scan()

while len(available_wifi_networks) == 0:
    print("Waiting for wifi.scan() to return something...")
    time.sleep(1)
    available_wifi_networks = wifi.scan()
else:
    for i in available_wifi_networks:
        print (i)

It just keeps outputting

Output:
Waiting for wifi.scan() to return something...
