Port, board and/or hardware
pico w
MicroPython version
MicroPython v1.25.0 on 2025-04-15; Raspberry Pi Pico W with RP2040
Reproduction
import network
import time
from time import sleep
import urequests
import gc
WLAN_SSID = 'MYSSID'
WLAN_PASSWORD = '123'
wlan = network.WLAN(network.STA_IF)
counter = 1
while True:
print('Start round {}'.format(counter))
wlan.active(True)
wlan.connect(WLAN_SSID, WLAN_PASSWORD)
for i in range(20):
if wlan.isconnected():
break
print('Trying to connect... Status is: ', wlan.status())
time.sleep(1)
if wlan.isconnected():
response = urequests.get('https://www.google.com')
response.close()
print('Deactivate WLAN...')
print('Memory alloc {}'.format(gc.mem_alloc()))
print('Memory free {}'.format(gc.mem_free()))
wlan.disconnect()
wlan.active(False)
wlan.deinit()
print('Sleeping...')
time.sleep(5)
counter += 1
Expected behaviour
Should not hang
Observed behaviour
This script works approx. 10-30 times and then it suddenly hangs. It seems to be the
deinit() function which causes the freeze.
I tested several pico w hardware, but same problem.
