version: 0.1.4
issue: The following error still exist , #14 null referencing error). Please update source and npm module.

I need to know why this error happens before settling on a way to fix it. It shouldn't happen in the first place, so how do we end up with onclose firing when self.ps is null ?

If you can help with that you're more than welcome.

connect two chrome cast in a network and change the app id in the following code.

var Client = require('castv2').Client,
    mdns = require('mdns');

var browser,
    detectedPlayers={},
    searchProgress = false;

function createBus(host,name) {
    var target ={};

    target.isConnected = true;
    target.ip = host;
    target.connection = null;
    target.heartbeat = null;
    target.receiver = null;
    target.liveTimer = null;
    target.client = new Client();


    target.client.connect(host, function() {

        target.connection =  target.client.createChannel(name,'receiver-0', 'urn:x-cast:com.google.cast.tp.connection', 'JSON');
        target.heartbeat  =  target.client.createChannel(name, 'receiver-0', 'urn:x-cast:com.google.cast.tp.heartbeat', 'JSON');
        target.receiver   =  target.client.createChannel(name, 'receiver-0', 'urn:x-cast:com.google.cast.receiver', 'JSON');


        target.connection.send({ type: 'CONNECT' });

        target.connection.on('error',function(){
            console.log('error in connection');
        })
        target.connection.on('message',function(msg){
            console.log(msg);
        })

        target.liveTimer = setInterval(function() {
            target.heartbeat.send({ type: 'PING' });
            target.receiver.send({"type": "GET_STATUS"})
        }, 10000);

        target.heartbeat.on('error',function(){
            console.log('error in heartbeat');
        })

        target.receiver.send({ type: 'LAUNCH', appId: 'app id goes here', requestId: 1 });

        target.receiver.on('error',function(){
            console.log('error in receiver');
        })

        target.receiver.on('message', function(data, broadcast) {
            if(data.type = 'RECEIVER_STATUS') {
                console.log(data);

                if(data.reason == 'CAST_INIT_TIMEOUT'){
                    target.receiver.send({ type: 'LAUNCH', appId: 'app id goes here', requestId: 1 });
                }

                if(data.status && data.status.isStandBy){
                    //clearInterval(target.liveTimer);
                    //target.connection.close();
                    //target.heartbeat.close();
                    //target.receiver.close();
                    //target.client.close();
                    target.isConnected = false;

                }
            }
        });
    });

    target.client.on('error',function(err){
        console.log('error',err);
        //clearInterval(target.liveTimer);
        target.isConnected = false;
    })

    target.client.on('close',function(err){
        console.log('close',err);
        //clearInterval(target.liveTimer);
        target.isConnected = false;
        console.log(detectedPlayers);

    })
    target.client.on('message',function(msg,msg1){
        console.log('message ',target.ip,msg.msg1);
    })

     detectedPlayers[host] = target;
}

function searchDevice(){
    console.log('launching discovery service')
    browser = mdns.createBrowser(mdns.tcp('googlecast'));
    searchProgress = true;
    browser.start();

    browser.on('serviceUp', function(service) {
        var castIP = service.addresses[0],
            castname = service.name;
        if(!detectedPlayers[castIP] || !detectedPlayers[castIP].isConnected){
            createBus(service.addresses[0],castname);
        }
    });
    browser.on('serviceDown', function(service) {
        console.log("service down: ", service);
    });
}

searchDevice();

setInterval(function(){
        if(browser)
            browser.stop();
        searchDevice();
    },30*1000);

Please correct me if anything is wrong. And add your custom receiver number in target.receiver.send

I don't have two Chromecasts unfortunately. Please run your code code with DEBUG=* node yourscript.js and post the log.
