BLE Firmata

Arduino Firmata implementation on BLE (Bluetooth Low Energy) and Node.js.

Build Status

  • Firmata is a protocol to controll Arduino from software on PC.
    • You can embed Arduino code into Node.js application.
  • supports BlendMicro.
    • also should works on BLE Shield, but I dont't have it.

Install

% npm install ble-firmata

Requirements

Usage

Samples

Setup

Connect

var BLEFirmata = require('ble-firmata');
var arduino = new BLEFirmata();

// search device with BLE peripheral name
arduino.connect("BlendMicro");

// search with default name "BlendMicro"
arduino.connect();

arduino.on('connect', function(){

  console.log("board version"+arduino.boardVersion);
  // your-code-here

});

Reset

arduino.reset(callback);

Close

arduino.close(callback);

I/O

Digital Write

arduino.digitalWrite(13, true, callback);
arduino.digitalWrite(13, false, callback);

Digital Read

arduino.pinMode(1, BLEFirmata.INPUT);
console.log( arduino.digitalRead(1) ); // => true/false

Digital Read (event)

arduino.pinMode(1, BLEFirmata.INPUT);

arduino.on('digitalChange', function(e){
  console.log("pin" + e.pin + " : " + e.old_value + " -> " + e.value);
});

Analog Write (PWM)

setInterval(function(){
  var an = Math.random()*255; // 0 ~ 255
  arduino.analogWrite(9, an, callback);
}, 100);

Analog Read

console.log( arduino.analogRead(0) ); // => 0 ~ 1023

Analog Read (event)

arduino.on('analogChange', function(e){
  console.log("pin" + e.pin + " : " + e.old_value + " -> " + e.value);
});

Servo Motor

setInterval(function(){
  var angle = Math.random()*180; // 0 ~ 180
  arduino.servoWrite(11, angle, callback);
}, 1000);

Sysex

Send

arduino.sysex(0x01, [13, 5, 2], callback);  // command, data_array, callback

Register Sysex Event

arduino.on('sysex', function(e){
  console.log("command : " + e.command);
  console.log(e.data);
});

Debug

set DEBUG env var

% DEBUG=ble-firmata node samples/analog_write.js
% DEBUG=*ble* node samples/analog_write.js

Test

Install SysexLedBlinkFirmata into Arduino

Run Test

% npm install
% npm test
