      I have not access to my home WiPy now
      but there is really simple code - i write it from my memory:

      First WiPy. in STA mode

      wlan = WLAN(mode=WLAN.STA)
nets = wlan.scan() 
print(str(nets))
wlan.connect(ssid='wipy-xxxx-a8', auth=(WLAN.WPA2, 'www.pycom.io'))
while not wlan.isconnected():
      machine.idle()
print('connected')

      Second WiPy run in default AP mode without modification

      and i never got 'connected' message
      only output like:

      n:6 0, o:6 1, ap:255 255, sta:6 1, prof:6
n:6 1, o:6 0, ap:255 255, sta:6 1, prof:6
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0

      all with recent software 0.9.5

        this is my code - in file 'wifi_sta.py' and i execute it from boot.py as execfile('wifi_sta.py'):

        import pycom
import machine
from network import WLAN

print('wifi_sta')
pycom.heartbeat(0)
pycom.heartbeat(1)
pycom.rgbled(0x00ff00)

wlan = WLAN(mode=WLAN.STA)
nets = wlan.scan()
for net in nets:
   print(str(net.ssid))
if not wlan.isconnected():
	#wlan.ifconfig(config=('192.168.4.2', '255.255.255.0', '192.168.4.1', '192.168.4.1'))
	#wlan.connect('wipy-wlan-a8be', auth=(WLAN.WPA2, 'www.wipy.io'), timeout=5000)
	wlan.connect('wipy-wlan-6ec2', auth=(WLAN.WPA2, 'www.wipy.io'), timeout=5000)	

	while not wlan.isconnected():
		machine.idle() # save power while waiting		
	print('WLAN connection succeeded!')
	pycom.heartbeat(0)
	pycom.heartbeat(1)
	pycom.rgbled(0x00ff00)

        also if you uncomment line

        wlan.ifconfig(config=('192.168.4.2', '255.255.255.0', '192.168.4.1', '192.168.4.1'))

        and also if i change

        while not wlan.isconnected():
		machine.idle()

        to
        pass
        time.sleep_ms(10)

          Any help? Can someone successfully connect two Wipy 2 together?

            @livius. I'm going to run some tests later and come back to you with a result.

              @livius, I tried something similar to your setup, and wasn't able to reproduce it. Using two LoPys (internally just a WiPy with the LoRa radio attached), I proceed to connect over serial port to both. Did this in one of them over the REPL:

              from network import WLAN

wlan = WLAN(mode=WLAN.STA)
nets = wlan.scan() # just to get a list
print(str(nets))

wlan.connect(ssid='lopy-wlan-be54', auth=(WLAN.WPA2, 'www.pycom.io')) # put your ssid here

# waited for a few seconds (counted to 10)
wlan.isconnected() # this printed true

              That's the most trivial test I could run. To rule out some possible causes, I want to ask you to try the same, using your own ssid, over serial REPL, and come back with the results to me.

              PS: I also tried the version with the loop, and it worked the way it's supposed

                  @livius, ok, at least we know you get similar results to me. Let me try again to reproduce yours. Thanks a lot for your feedback.

                      @livius, I've been caught in several things but I didn't forget you. If you can place your code in pastebin and pass the link, that will let us reproduce it perfectly ;)
