Live demonstrations

Really dumb NodeJS code sample

// Load HTTP module
var httpmod = require('http');

// Create HTTP server
httpmod.createServer(function (req, res) {

// Content header
res.writeHead(200, {'content-type': 'text/plain'});

// Write message and signal communication is complete
res.end("Hello, Tizen World!\n");
}).listen(8088);

// This presentation is very boring
console.log('Server running on 8088');

Run this NodeJS code on your smartphone!

MQTT JavaScript code sample 1

// Simple publish client

var mqtt = require('mqtt'), locli = mqtt.createClient();
locli.publish('messages', 'Mqtt');
locli.publish('messages', 'is pretty cool');
locli.publish('messages', 'remember that!', {retain: true});
locli.end();

Publishing messages via MQTT to the broker

MQTT JavaScript code sample 2

// Simple subscribe client

var mqtt = require('mqtt') , locli = mqtt.createClient();
locli.subscribe('messages');
locli.publish('messages', 'Hello from me!');
locli.on('message', function(topic, message) {
  console.log(message);
});

// disable automatic reconnect
locli.options.reconnectPeriod = 0;

Subscribing to topics via MQTT from the broker

Human controlling the IoT or…

nodes controlling the human?
