How to set a specific IP Address in boot.py



  • I have added the following code to my boot.py file and it works fine, however my board gets a dynamic IP address from my router DHCP server.

    How can I change the code to set a static IP Address.

    # boop.py
    known_nets = [('***********', '***********')] # change this line to match your WiFi settings
    
    import machine
    import os
    
    uart = machine.UART(0, 115200) # disable these two lines if you don't want serial access
    os.dupterm(uart)
    
    if machine.reset_cause() != machine.SOFT_RESET: # needed to avoid losing connection after a soft reboot
        from network import WLAN
        wl = WLAN()
    	
        # save the default ssid and auth
        original_ssid = wl.ssid()
        original_auth = wl.auth()
    
        wl.mode(WLAN.STA)
    	
        available_nets = wl.scan()
        nets = frozenset([e.ssid for e in available_nets])
    
        known_nets_names = frozenset([e[0] for e in known_nets])
        net_to_use = list(nets & known_nets_names)
    
        try:
            net_to_use = net_to_use[0]
            pwd = dict(known_nets)[net_to_use]
            sec = [e.sec for e in available_nets if e.ssid == net_to_use][0]
            wl.connect(net_to_use, (sec, pwd), timeout=10000)
        except:
            wl.init(mode=WLAN.AP, ssid=original_ssid, auth=original_auth, channel=6, antenna=WLAN.INT_ANT)
