Port of the Adafruit BluefruitLE nRF51 library for Particle

A sample program is in firmware/examples/atcommand.ino. It allows you to type serial commands directly to the Bluefruit from the USB serial device.

SPI

This code works with the [Adafruit Bluefruit LE SPI Friend] (https://www.adafruit.com/products/2633).

For your own code, you will need to include these files:

#include "Adafruit_BLE/Adafruit_BLE.h"
#include "Adafruit_BLE/Adafruit_BluefruitLE_SPI.h"

You’ll also need to create an object to interface with the Bluefruit and assign pins:

Adafruit_BluefruitLE_SPI ble(&SPI, BLUEFRUIT_SPI_CS, BLUEFRUIT_SPI_IRQ, BLUEFRUIT_SPI_RST);

Sample connections as configured in the atcommand.ino sample file:

  • SCK - A3
  • MISO - A5
  • MOSI - A4
  • CS - A2 (can use any pin)
  • IRQ - D3 (can use any pin, does not use a hardware interrupt)
  • RST - D2 (can use any pin)
  • GND - GND
  • VIN - 3V3

You can use the SPI1 hardware SPI port if you prefer.

UART (Serial)

The software can also be used with the [Adafruit Bluefruit LE UART Friend] (https://www.adafruit.com/products/2479).

#include "Adafruit_BLE/Adafruit_BLE.h"
#include "Adafruit_BLE/Adafruit_BluefruitLE_UART.h"
// Optional, set to -1 her and leave MODE unconnected if not using
#define BLUEFRUIT_UART_MODE_PIN            -1

Adafruit_BluefruitLE_UART ble(&Serial1, BLUEFRUIT_UART_MODE_PIN);

Connections:

  • MOD - Optional for changing between modes (see note below)
  • CTS - Must connect to GND!
  • TXD - Connect to Photon/Electron RX pin
  • RXI - Connect to Photon/Electron TX pin
  • VIN - Connect to 3V3
  • RTS - No connection
  • GND - Connect to GND
  • DFU - No connection

The Adafruit board has a switch that choose between CMD and UART mode. You can also control this through software by connecting the MOD pin to a output. Specify the pin wit BLUEFRUIT_UART_MODE_PIN.

On the Particle Electron, you can also use Serial4 (TX=C3, RX=C2) or Serial5 (TX=C1, RX=C0).

Updates

Version 0.0.3 - Fixed compatibility with mesh devices (Argon, Boron, Xenon) due to redeclaration of err_t.
