LoPy4 boot.py Wifi

[nemke.petrovic]

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 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/

[nemke.petrovic]

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

@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
    wlan.antenna(WLAN.EXT_ANT)
    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
                break
            print('.', end='')
            time.sleep_ms(200)
        else:
            print("Connect attempt timed out\n")
            return
    print('\nnetwork config:', wlan.ifconfig())

do_connect()

WIFI_SSID and WIFI_PASSWD have to be set accordingly.

[nemke.petrovic]

import machine
import time
from network import WLAN
wlan = WLAN() # get current object, without changing the mode

if machine.reset_cause() != machine.SOFT_RESET:
    wlan.init(mode=WLAN.STA)
    # 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
        break

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 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.
