AYUDA!! Bluefruit nRf51 como HID Bluetooth

Hola a todos:

Estoy construyendome una botonera de 20 botones y 6 rotarys , para la cual he empezado utilizando un Arduino Leonardo, aprovechando este codigo.Mi intencion es dotar de Bluetooth a la botonera,por lo que he comprado una placa Bluefruit Feather nRf51, pero me veo perdido a la hora de implementar esta funcionalidad.

Alguien me echa un cable? Mil gracias de antemano

//Simple buttonbox sketch
//Supports up to 25 buttons and up to 4 encoders
//version 0.2 by TOPMO3
//
//
//Arduino IDE 1.6.6 (or above) !
//
//Joystick library from Matthew Heironimus, GitHub - MHeironimus/ArduinoJoystickLibrary: An Arduino library that adds one or more joysticks to the list of HID devices an Arduino Leonardo or Arduino Micro can support.
//
//Encoders code from Ben Buxton
//More info: Buxtronix: Rotary encoders, done properly
//
//Thank you guys!
