Arduino BLEPeripheral
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
- RedBearLab
- Femtoduino
- Olimex
- Jaycon Systems
- TinyCircuits
- TinyShield Bluetooth Low Energy - Nordic
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.
