AYUDA!! Bluefruit nRf51 como HID Bluetooth
Publicado por Javier (2 intervenciones) el 19/02/2019 17:08:45
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
