pywifi crossplatform library for connecting to Cozmo WIFI server (example)

[CozmoCyke]

PyCozmo can only send command to Cozmo when the computer is connected to Cozmo WIFI server ! But now there's no code to connect your application to Cozmo wifi in PyCozmo.

Then I have try to use pywifi library to connect programmatically to Cozmo wifi ! This library is crossplatform.

https://pypi.org/project/pywifi/
https://github.com/awkman/pywifi

Example working with Windows 7 and last dev PyCozmo branch :

import pywifi
from pywifi import const
import time
import pycozmo

def pycozmo_program(cli: pycozmo.client.Client):

    cli.set_head_angle(pycozmo.MAX_HEAD_ANGLE.radians)
    time.sleep(1)
    cli.set_head_angle(pycozmo.MIN_HEAD_ANGLE.radians)
    time.sleep(1)

    cli.set_lift_height(pycozmo.MAX_LIFT_HEIGHT.mm)
    time.sleep(1)
    cli.set_lift_height(pycozmo.MIN_LIFT_HEIGHT.mm)
    time.sleep(1)

wifi = pywifi.PyWiFi()

ssid_Cozmo = 'Cozmo_' # add the Cozmo number
pw_Cozmo = '' # put Cozmo WIFI password with the dashes "-" ! 


iface = wifi.interfaces()[0]

iface.disconnect()
time.sleep(1)
assert iface.status() in\
    [const.IFACE_DISCONNECTED, const.IFACE_INACTIVE]

profile = pywifi.Profile()
profile.ssid = ssid_Cozmo
profile.auth = const.AUTH_ALG_OPEN
profile.akm.append(const.AKM_TYPE_WPA2PSK)
profile.cipher = const.CIPHER_TYPE_CCMP # = AES
profile.key = pw_Cozmo

iface.remove_all_network_profiles()
tmp_profile = iface.add_network_profile(profile)

iface.connect(tmp_profile)
time.sleep(30)
assert iface.status() == const.IFACE_CONNECTED

pycozmo.run_program(pycozmo_program)

#iface.disconnect()
#time.sleep(1)
#assert iface.status() in\
#    [const.IFACE_DISCONNECTED, const.IFACE_INACTIVE]

I just experimented with this. many modern Linux distros use nmcli now to control networks, pywifi uses wpa_cli which is not set up to be run without root in these aforementioned modern Linux distros.
