I need a simple C# app that can,
1) Run on IOS and Android.
2) Has two buttons titled ON and OFF
3) Connect to an ESP32 device via bluetooth. (MAC address can be hardcoded)
4) Upon pressing ON an LED connected with the ESP32 must turn ON.
5) Upon pressing OFF the LED must turn OFF.
The C# app code MUST be INTERUPT based, i.e. no constant polling of buttons.
The ESP32 code MUST be INTERRUPT based. When a button is pressed on the app, a Bluetooth interrupt must get triggered on the ESP32.
I will need complete C# code, as well as step by step instructions on how to deploy the app.
Please write LEDBLNKAPP at the start of your bid, so that it becomes clear that you have read the specifications.
