From Arduino IDE with Arduino/Genuino 101 board installed, it's a CallbackLED example to test Arduino/Genuino 101 Bluetooth Low Energy (BLE) capabilities to turn on and of the LED connected to Pin 13 from a Android or iOS.


In Arduino IDE, open and download the CallbackLED example:

On smartphone with BLE, download "nRF Master Control Panel (BLE)" app:
nRF Master Control Panel is a powerful generic tool that allows you to scan, advertise and explore your Bluetooth Smart (BLE) devices and communicate with them. nRF MCP supports number of Bluetooth SIG adopted profiles including Device Firmware Update profile (DFU) from Nordic Semiconductors.
- Android
- iOS
