Hi,
I have blynk-service.js located in /root/.
I've test that command node /root/blynk-service.js executes and blynk-service.js works correctly. This script runs connection to Blynk server (application). When script runs Blynk app on Android reports that Omega is online.

If I put a line inside rc.local:
node /root/blynk-service.js script executes but I can't run other commands (ie. from serial terminal, reboot command won't execute) and startup sequence doesn't finish because orange LED on Omega2+ doesn't stop blynking after reboot.
If I put a line node /root/blynk-service.js & or node /root/blynk-service.js 2>&1
then it looks like script doesn't start. I can run other commands.

I've tested init.d - but I have same results.
I wrote blynk-service script inside /etc/init.d/, chmod +x blynk-service. Script has code:

START=98
STOP=10

start() {
        echo start
        /usr/bin/node /root/blynk-service.js 2>&1
}

stop() {
        echo stop
}

restart()
{
        stop
        start
}

I've test that command /etc/init.d/blynk-service run works.

I've read the topics regarding this problem, but none of them abswers completely the question how to automatically run (and restart if it breaks) node.js script after startup.

To conclude,
If I run the script from serial Terminal using command node /root/blynk-service.js it works ok.
If it's run from rc.local withoust '&' caharacter at the end of command, it works ok. All other ways of starting the script using init.d or rc.local produces the state in which Omega isn't connected to Blynk app.

@Mario-Simunic
I'm running FW omega2p-v0.2.0-b186 on Omega2+
When I run My node.js script manually after startup, everythings fine until I dissable My WiFi router (to test reconection to blynk).
Then:
blynk.on('disconnect', function() { console.log("DISCONNECT"); });
doesn't happen.

After I anable WiFi again, serial Console puts message:

events.js:146
      throw err;
      ^

Error: Uncaught, unspecified "error" event. (ECONNRESET)
    at emit (events.js:144:17)
    at Blynk.error (/usr/bin/blynk-library/blynk.js:589:8)
    at null.<anonymous> (/usr/bin/blynk-library/blynk.js:552:48)
    at emitOne (events.js:77:13)
    at emit (events.js:169:7)
    at TLSSocket.<anonymous> (/usr/bin/blynk-library/blynk-node.js:204:16)

    at TLSSocket.emit (events.js:169:7)
    at emitErrorNT (net.js:1255:8)
    at nextTickCallbackWith2Args (node.js:437:9)

So, there is no automatic connection status response.
Also, it looks like reconnection to Blynk server fails somewhere.

blynk.virtualWrite(v0, 0); // Does nothing, but it should update button in App connected to V0

Hi,
I'm new to the Omega so I would like to get some better understanding how things works. I can't find proper documentation of Blynk library and available methods inside object var blynk = new BlynkLib.Blynk (token);

Things that I would like to uderstand better is:

• what is propper way to run node.js script automatically after startup (this would be my program or application if you like)
• how to properly detect connection and disconnection of apcli0 wifi network
• how to properly detect and handle connection and disconnection to the Blynk service (server)
• how to fast (as possible) toggle GPIO from node.js

I have writen my application in node.js. It works almost fine, but there are some issues.

• One thing that bothers me is that if Omega starts up without WiFi application available then My application starts and can't connect Blynk. So,

blynk.on('connect', function(){
// some acctions
});

never happens.

• Another issue is that if for some reason, wifi drops during work, Blynk won't reconnect.
  But, both issues dosn't exist if I login to console (after startup) and manually start node.js script.

Please advise,
