Wipy2 reboots after connecting to WiFi AP (wlan.connect)

[rodri16]

Hi I am trying to connect Wipy2 (v0.9.7.b1) to my WiFi AP, but after the connection the device reboots. Any suggestion?

The simple code I am running is this:

from network import WLAN
wlan = WLAN(mode=WLAN.STA)
wlan.connect('MarconiLab', auth=(WLAN.WPA2, 'marconi-lab'), timeout=5000)
I (437945) wifi: n:11 0, o:6 0, ap:255 255, sta:11 0, prof:6
I (438921) wifi: state: 0 -> 2 (b0)
I (438923) wifi: state: 2 -> 3 (0)
I (438927) wifi: state: 3 -> 5 (10)
I (438939) wifi: connected with MarconiLab, channel 11

Here is the code I use to connect to a network. Not sure this is much help, I have only just started working with WiPy 2.0 myself.

import time
import network
from network import WLAN
wlan = network.WLAN(mode=WLAN.STA)
wlan.connect('station ssid', auth=(WLAN.WPA2, 'password'))
print ('conneting - please wait.')
while not wlan.isconnected():
time.sleep_ms(50)
print ('Conneted')
print(wlan.ifconfig())

The response is:

Soft resetting the WiPy

Switch from MacaroniLab to SpagettiLab for the wifi SSID that will fix your config. As an alternativ you can try upgrading to the new 1.0.0 firmware. That fixes an IPv6 packet issue on wifi. Trust me;-)
