I'm using an arduino mega and the esp8266 (wifi module for arduino). I want to start with something simple and just toggle an led when I press an button on my application, the ESP works with wifi and I know the IP ardess, I don't know if I have to look to connect the app with wifi or something. Is there anyone who knows how I can make an connection between my Xamarin application and my ESP8266, my ESP8266 will tell the Arduino that the button was pressed and than the arduino will toggle the LED. So is it possible to make a connection with my Xamarin androidphone application and the ESP. Or if it's not possible., is it possible to make a connection between the app and my arduino. The ESP is just to make the connection between my phone and arduino wireless.
Any help appreciated!
