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

Note: Does not require use of nRFgo Studio! However, uses more code space.

Nordic Semiconductor nRF51822

WARNING: Adafruit nRF51 boards are NOT compatible with this library, this includes the Bluefruit LE UART Friend, Bluefruit LE SPI Friend, Bluefruit LE Shield, Flora Wearable Bluefruit LE Module, Feather 32u4 Bluefruit LE, and Feather M0 Bluefruit LE.

Compatible IDE's and MCU's

Warning: For more advanced sketches an MCU with more than 2kB of RAM and 32kB of flash space is recommended. Advance sketches include:

  • Multiple services and characteristics
  • HID API usage


Download Library


Using the Arduino IDE Library Manager

  1. Choose Sketch -> Include Library -> Manage Libraries...
  2. Type BLEPeripheral into the search box.
  3. Click the row to select the library.
  4. Click the Install button to install the library.

Using Git

cd ~/Documents/Arduino/libraries/
git clone BLEPeripheral


cd ~/Documents/mpide/libraries/
git clone BLEPeripheral
