ble-io

Ble-io is a library for writing javascript programs that interact with Bluetooth Low-Energy (BLE) devices. It can also be used an IO plugin for use with the johnny-five robotics framework.

The intention is to be able to use a simple and generic API for interacting with the GPIO pins across many different types of BLE peripherals.

Ble-io was built at IcedDev

Installation

npm install ble-io

Getting Started

In order to use the ble-io library, you will need to load a firmware onto the BLE peripheral that supports the ble-io Service and Characteristics described here.

One implementation of the ble-io service is for Intel curie based boards including the Arduino 101 and TinyTile here: firmware

Usage

const BleIO = require("ble-io");
const io = new BleIO();
 
io.on("ready", function() {
  //turn on pin 13
  this.digitalWrite(13, 1);
});

With johnny-five

const BleIO = require("ble-io");
const five = require("johnny-five");
 
const board = new five.Board({
  io: new BleIO()
});
 
board.on("ready", function() {
  cosnt led = new five.Led(13);
  led.blink(500);
});

TODO

• We need a way to query pin capabilities. Right now the code is assuming 20 pins all able to accept any pin mode.
• i2C support needs to be added as a new Characteristic to the reference firmware
