[SOLVED] WidgetLED in Raspberry Pi2 iPhone Blynk App

Need Help With My Project
22

I declare the variable v8 like a WidgetLED

var v8 = new blynk.WidgetLED(8);

and I put it to 255 for turn On the led,no?

v8.setValue(255);

I also test:

v8.turnOn();
v8.turnOn(‘read’, function() { v8.write(255);});

We are use the NodeJS in Raspberry Pi 2, , but the led not work in the APP

23

@FaramiR is that full code? Does other widgets work?

what about this https://github.com/vshymanskyy/blynk-library-js/blob/master/examples/nodejs/client-tcp.js does it work for you?

24

I have 5 esp8266, connect at raspberry by web socket. All data is in the raspberry, and Blynk only has a project.
I parse all data in Blynk , for show the información in the APP.
I have temperatures and others float variables. All is working OK, but the booleans not turn on the leds widgets

You can see my test in v8 / v9 / v10

function convertVar(value){
if (value == 1){
return true;
}
else {
return false;
}
}

Yes, it work for me. All is OK, less the Widget LED

Hi, i have the same problem. I work with a Raspberry Pi and NodeJS… and IOS 9 with an iPhone 6.

#!/usr/bin/env node

var Blynk = require('/home/pi/node_modules/blynk-library-js');

var AUTH = '********'; 

var blynk = new Blynk.Blynk(AUTH, options = {
  connector : new Blynk.TcpClient()
});

var v1 = new blynk.VirtualPin(1);
var v2 = new blynk.VirtualPin(2);
var v8 = new blynk.WidgetLED(8);
var v9 = new blynk.WidgetLED(9);

v1.on('write', function(param) {
  console.log('V1:', param);
});
v2.write(255);
v8.turnOn();
v9.setValue(255);


blynk.on('connect', function() { console.log("Blynk ready."); });
blynk.on('disconnect', function() { console.log("DISCONNECT"); });

**** I tried with all components and works well with everyone except with LED … :cry:
Thanks in advance!!!

@vshymanskyy please have a look.

Please try this code:

#!/usr/bin/env node

var Blynk = require('/home/pi/node_modules/blynk-library-js');

var AUTH = '********'; 

var blynk = new Blynk.Blynk(AUTH, options = {
  connector : new Blynk.TcpClient()
});

var v1 = new blynk.VirtualPin(1);
var v2 = new blynk.VirtualPin(2);
var v8 = new blynk.WidgetLED(8);
var v9 = new blynk.WidgetLED(9);

v1.on('write', function(param) {
  console.log('V1:', param);
});

blynk.on('connect', function() {
  console.log("Blynk ready.");
  v2.write(255);
  v8.turnOn();
  v9.setValue(255);
});
blynk.on('disconnect', function() { console.log("DISCONNECT"); });

You can only send commands when connected…

Works, thank you very much !!!

I what editor o program do you use that ?
