Willing to add wifi connections from a kivy app and I'm using a simple function to edit wpa_supplicant.conf file adding there new networks.

My function correctly writes the configuration there and seems identical to the configs aded through raspbian GUI...

But when I reboot the raspberry, it says no networks interfaces were found but it get solved if I delete the last added lines from the wpa_supplicant.conf file. For some reasons raspbian fails to read properly this file after the edit, but I don't see what I'm doing wrong here which defers from the default configurations.

Hope someone can provide me some hint... I run the script as sudo, so can't be any permission issues, I tried to look into any diferences in the way I write the config and the config provided by raspbian, but no clue...

Here you can see the code:

def CreateWifiConfig(SSID, password):
        config = (
                '\nnetwork={{\n' +
                '\tssid="{}"\n' +
                '\tpsk="{}"\n' + '}}').format(SSID, password)
        with open("/etc/wpa_supplicant/wpa_supplicant.conf", "a+") as wifi:
        print("Wifi config added")```
