Bean-io

Bean-io is a Firmata-compatibility IO class for writing node programs that interact with LightBlue Bean devices. Bean-io was built at IcedDev

Installation

npm install bean-io

Getting Started

In order to use the bean-io library, you will need to load examples->Firmata-Standard Firmata onto your Bean device. We recommend you review Punchthrough's Getting Started guide before continuing.

Linux Instructions

Make sure that libbluetooth-dev and bluez libraries are installed before installing bean-io.

Blink an Led

The "Hello World" of microcontroller programming:

var beanio = require("bean-io");
var board = new beanio.Board({
  timeout: 30000 //optional - defaults to 30 seconds
  // uuid: 'myUuid' //optional - will use first bean found
});

board.on("ready", function() {
  console.log("CONNECTED");
  this.pinMode(13, this.MODES.OUTPUT);

  var byte = 0;

  // This will "blink" the on board led
  setInterval(function() {
    this.digitalWrite(13, (byte ^= 1));
  }.bind(this), 500);
});

Johnny-Five IO Plugin

Bean-IO can be used as an IO Plugin for Johnny-Five:

var five = require("johnny-five");
var beanio = require("bean-io");
var board = new five.Board({
  io: new beanio.Board()
});

board.on("ready", function() {
  var led = new five.Led({pin: 13});
  led.blink();
});

API

Bean-IO subclasses firmata.js and provides the same API.
