Hello,

Does anybody have a solid method to automatically restore the Wifi connection on an ESP32 after losing it, for instance after a router reboot?

Thanks a lot!

Regards,
Ronald

This is what I use

function wifiConnect() {
  wifi = require('Wifi');
  wifi.connect(wifi_options.ssid, { password: wifi_options.password },
    (e)=> {
      if (e) {
        print("WIFI: " + e);
      }
  });
  wifi.on('connected', ()=> {
    print('WIFI:', wifi.getIP());
  });
  wifi.on('disconnected', ()=> {
    print("WIFI: Reconectando...");
    wifi.connect(wifi_options.ssid, {password: wifi_options.password});
  });
}

Perfect, thanks a lot! I did not expect the disconnected event to trigger when connect() fails.
