9 months ago Hi,
Put together this simple wifi connect function whilst implementing an MQTT channel on my Badger 2040W (with very useful info from: https://core-electronics.com.au/guides/getting-started-with-mqtt-on-raspberry-pi-pico-w-connect-to-the-internet-of-things/).
Never tried connecting to open networks, but this would allow multiple connect tries and reporting, which should help with finding the solution.
Good luck .... Gerry
Code____
import network from time import sleep
ssid = 'myssid' password = 'mypassword' # or whatever required for open network ???
def connect_to_wifi(max_connection_tries):
print(" connecting to network ")
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(ssid, password)
for i in range(0, max_connection_tries):
connect_tries = i
print("** network connection try: " + str(connect_tries))
if not wlan.isconnected():
connect_status = 'Not Connected'
connection = (0,0,0,0)
print('... Waiting for connection ... try#: ' + str(connect_tries))
sleep(1)
else:
connection = wlan.ifconfig()
connect_status = 'Connected'
break
return connection, connect_status, connect_tries
Test
connection_attempts = 20 # or whatever ... connection, connect_status, connect_tries = connect_to_wifi(connection_attempts) print(connection) print(connect_status) print(connect_tries)

Our school uses heavily filtered, unsecured wireless - mainly for any non-staff devices.
Our recently bought Badger 2040Ws don't want to connect to the unsecured WiFi (standard Raspberry Pis connect fine). We've tried several variations in the WIFI_CONFIG.py file, but without any luck.
We've tried: PSK = "" PSK = None Adding a line with: KEY_MGMT = None Replacing the PSK line with: KEY_MGMT=None
I've tried taking a look at net_info.py, but it only seems to pass the SSID and PSK from WIFI_CONFIG.py
Any ideas guys?
