Hello there,
My project has a wifi connection and the set up looks like this:
My question:

how to prioritize networks? If two network is avaible, prefer one then the other. In this setup it goes the first in the ABC.
I added a block if no known network found, then sleep for minute and search again. But somehow always goes to the else part. Can you hint why?
Is there a tool to debug the micropython code? It would be helpful sometimes
do you have any other tips? Thanks in advance! :)

while not wlan.isconnected():
    for net in nets:
        if net.ssid == '******':
            print(str(net.ssid)+" found!")
            lcd.putstr(str(net.ssid)+" found!")
            wlan.connect("******", auth=(WLAN.WPA2, "*****"), timeout=5000) 
        elif net.ssid == '***':
            print(str(net.ssid)+" found!")
            lcd.putstr(str(net.ssid)+" found!")
            wlan.connect("***", auth=(WLAN.WPA2, "*******"), timeout=5000)
        elif net.ssid == '******':
            print(str(net.ssid)+" found!")
            lcd.putstr(str(net.ssid)+" found!")
            wlan.connect("******", auth=(WLAN.WPA2, "*********"), timeout=5000)
        else:
            lcd.clear()
            lcd.putstr("No network, sleeping for 1 min")
            lcd.move_to(0, 1)
            lcd.backlight_off()
            machine.deepsleep(60000)
            machine.reset()
