Arduino BLEPeripheral

Build Status Gitter

An Arduino library for creating custom BLE peripherals with Nordic Semiconductor's nRF8001 or nR51822.

Enables you to create more customized BLE Peripheral's compared to the basic UART most other Arduino BLE libraries provide.

nRFgo Studio (and Windows) is not required when using the nRF8001.

Compatible Hardware

Nordic Semiconductor nRF8001

  • Adafruit
    • Bluefruit LE - nRF8001 Breakout
  • RedBearLab
    • BLE Shield
    • Blend Micro
