Call socket.io from dgram socket udp4 - json

Question

I'm having some problems with a small aplications that I'm developing.
I have an Arduino with a temperature sensor, I wanted to send the values to a nodejs service, and show it to a webpage. I wanted to use socket.io, but I'm just able to use UDP connection from arduino to server (ethernet). Just to keep the sensor value refreshed, seems that I have to call a io socket from the UDP service, but I can't.
My socket.io that works when I call it from a webpage.
var io = require('socket.io').listen(3000);
io.sockets.on('connection', function (socket) {
socket.on('message', function (message) {
console.log("Got message: " + message);
io.sockets.emit('SensorList', { 'temperature': temp });
});
});
This is the UDP service that reads the arduino packets:
var dgram = require("dgram");
var server = dgram.createSocket("udp4");
var fs = require('fs');
**var io = require('socket.io');**
var crlf = new Buffer(2);
crlf[0] = 0xD; //CR - Carriage return character
crlf[1] = 0xA; //LF - Line feed character
server.on("message", function (msg, rinfo) { //every time new data arrives do this:
console.log("server got: " + msg.readUInt16LE(0) + " from " + rinfo.address + ":" + rinfo.port); // you can comment this line out
**var socket = io.connect('http://localhost:3000');
socket.on('connect', function () {
socket.send(msg.readUInt16LE(0));
});**
});
server.on("listening", function () {
var address = server.address();
console.log("server listening " + address.address + ":" + address.port);
});
server.bind(6000); //listen to udp traffic on port 6000
The error is:
var socket = io.connect('http://localhostit.is:3000'); ^
TypeError: Object # has no method 'connect'
at Socket. (/Users/xfr/Documents/nodejs/temp1/app2.js:15:19)
at Socket.EventEmitter.emit (events.js:98:17)
at UDP.onMessage (dgram.js:437:8)
If I erase all the io part, I'm able to see the values in console.
If there is another way to mix 2 services in one.. tell me some clues and I'll do the search.
Thanks.

Made it!
2 in 1...
var http = require('http'),
dgram = require('dgram'),
socketio = require('socket.io');
var fs = require('fs');
var app = http.createServer(),
io = socketio.listen(app),
socket = dgram.createSocket('udp4');
var crlf = new Buffer(2);
crlf[0] = 0xD; //CR - Carriage return character
crlf[1] = 0xA; //LF - Line feed character
socket.on('message', function(content, rinfo) {
console.log('got message', content.readUInt16LE(0), 'from', rinfo.address, rinfo.port);
io.sockets.emit('udp message', content.readUInt16LE(0));
});
socket.bind(6000);
app.listen(8000);
On the webpage side:
src="socket.io.min.js"
src="jquery.min.js"
<script>
var socket = io.connect('http://local_host.com:8000');
socket.on('udp message', function(msg) {
console.log(msg) ;
temperature = msg/100;
$('#temperature h1').html(temperature+'°C');
});
</script>
bind/listen newbie issues.
