A library written in Node.js used to communicate with my Jarvis project

var types = require('../types');

module.exports = {

    if (config.CLOUD)

    var dgram = new Buffer(1);
    dgram[0] = 0xAA;

    return cb(null, dgram);

  },

    var mess = new Buffer(message || '');

      dgram.writeDoubleBE(hash, 1);
