Mystery with network.WLAN on a FiPy

[paul_tanner]

Line 5 throwing the error "OSError: the requested operation is not possible"
sounds like a problem with connect()
(I am, of course, using valid ssid and password)

import network
import time
wlan = network.WLAN(mode=network.WLAN.STA)
wlan.connect('your-ssid', auth=(network.WLAN.WPA2, 'your-key'))
while not wlan.isconnected():
    time.sleep_ms(50)
print(wlan.ifconfig())

Any ideas?

OK solved by using a different set of APIs from the micropython site.

import network
import machine
from network import WLAN
wlan = WLAN(mode=WLAN.STA)
nets = wlan.scan()
for net in nets:
    if net.ssid == '13GC':
        print('Network found!')
        wlan.connect(net.ssid, auth=(net.sec, 'tobytoby'), timeout=5000)
        while not wlan.isconnected():
            machine.idle() # save power while waiting
        print('WLAN connection succeeded!')
        break
print (wlan.ifconfig())

I conclude that there's a fair amount or documentation that can't be trusted, presumably because of "upgrades"

@paul_tanner What's the value of net.sec in you case?
