Celso, can you provide an example of connecting to sockei.io on server ? Thanks
Thanks for updating

@DouglasHennrich using this example you can connect mobile app to server using web socket!

var socketIO = require('socket.io'); //Socket io library or path to socket io lib
var socket = socketIO.connect('http://yourdomain.com', {
transports : ['websocket'],
timeout : 20000,
reconnection : true
});
socket.io.on('connect_error', function(e) {
console.info('Socket Manager - Connect error');
});
socket.io.on('reconnect_failed', function() {
console.info('Socket Manager - Reconnect failed');
});

socket.on('connect', function() {
console.info('Socket - Connect event received from server');
});
socket.on('disconnect', function() {
console.info('Socket - Disconnection event received');
});
socket.on('error', function() {
console.info('Socket - Error while connection');
});

For implement SocketIO into your server use official SocketIO docs: http://socket.io/docs/server-api/

enjoy!
