LoPy4 boot.py Wifi

  • Hi all
    I am new

    I like to have script in boot.py in Lopy4 for Wifi. So I have connection all time with devices. No mater waht happed to main.py code to have access to change it.
    Also I need to use external Antenna for wifi (alredy connected), so in script I like to specific antenna=WLAN.EXT_ANT and mode to be STE

    My wifi Network is secure auth=WPA2, and I like dhcp to assigne IP to LoPY4 (I configure MAC IP reservation on router, so same IP is given to module)

    Help. I need example of this script ?

  • @nemke-petrovic The break statement in the last line is wrong. That way, the code will not wait for a connection. And also, the antenna is internal.

  • import machine
    import time
    from network import WLAN
    wlan = WLAN() # get current object, without changing the mode
    if machine.reset_cause() != machine.SOFT_RESET:
        # configuration below MUST match your home router settings!!
    if not wlan.isconnected():
        # change the line below to match your network ssid, security and password
        wlan.connect('IoT Network', auth=(WLAN.WPA2, '19Akacki_Ryu86'), timeout=5000)
        while not wlan.isconnected():
            machine.idle() # save power while waiting

    Interesting, it doesn't work. I write new using examples from pycom documenty, end this is work.
    LoPy4 ver 1.20.2.rc6

    Many thanks for reply

  • @nemke-petrovic You could try that one, which is except for the antenna switch the one I am using:

    def do_connect():
        import network
        import time
        wlan = network.WLAN(mode=network.WLAN.STA) # create station interface
        if not wlan.isconnected():      # check if the station is connected to an AP
            wlan.connect(ssid=WIFI_SSID, auth=(network.WLAN.WPA2, WIFI_PASSWD))
            for _ in range(100):
                if wlan.isconnected():      # check if the station is connected to an AP
                print('.', end='')
                print("Connect attempt timed out\n")
        print('\nnetwork config:', wlan.ifconfig())

    WIFI_SSID and WIFI_PASSWD have to be set accordingly.

  • Yes, of course. But didn't manage to work.
    So, i write here maybe someone have working script

  • @nemke-petrovic you can put any code into boot.py. Did you have a look at the examples in the documentation? E.g. https://docs.pycom.io/tutorials/all/wlan/
