Adafruit nRF8001 Bluetooth LE

Adafruit nRF8001 library for Arduino

adafruit/Adafruit_nRF8001 is driver and example code for Adafruit's nRF8001 Bluetooth Low Energy Breakout.


(The Fritzing part of Adafruit nRF8001 can be download HERE)

The pin locations are defined in ble_system.h, the supported systems are defined in hal_aci_tl.cpp. The following pinout is used by default for the Arduino Uno:

SCK -> Pin 13
MISO -> Pin 12
MOSI -> Pin 11
REQ -> Pin 10
RDY -> Pin 2 (HW interrupt)
ACT -> Not connected
RST -> Pin 9
3V0 - > Not connected
VIN -> 5V
RDY must be on pin 2 since this pin requires a HW interrupt.

3V0 is an optional pin that exposes the output of the on-board 3.3V regulator. You can use this to supply 3.3V to other peripherals, but normally it will be left unconnected.

ACT is not currently used in any of the existing examples, and can be left unconnected if necessary.
