Control an LED from a Phone App
Send commands over BLE to your board.
Your First BLE Control
Time to put it together: tap a button on your phone and watch an LED turn on. This is BLE control in action. 💡
The Plan
The phone writes a value to a characteristic, your board reads it, and your sketch switches the LED to match. Simple and powerful.
