i have a very simple nwjs app that launch a script on start, this is my code:

var five = require('johnny-five');
var board = new five.Board();

board.on('ready', function() {
  var led = new five.Led(12);
  led.blink(500);
});

when i start the app, some arduino built-in leds blink then in the console i get this error:

i am using arduino mega 2560, and i uploaded a stranded firmata

Edit

i added this code to my script:

board.on('error', function(err) {
  alert(err)
});

and the app stop crashing, but no blinking :( the error is Error: A timeout occurred while connecting to the Board. i also tried to print the ports using the module serialport but i get this error:

Error: The module '/home/mohammed/node_modules/serialport/build/Release/serialport.node'

NODE_MODULE_VERSION 46. This version of Node.js requires

i solved the problem using a module called nwjs-j5-fix it is used to let you use j5 in nwjs

the code at the first line

nw.require("nwjs-j5-fix").fix();
