Codrova LED light on new GCM notification

Question

I'm in process of development of Cordova hybrid app. I was unable to find any information on how to turn on the LED of the phone when new notification from GCM is received. I currently have sound and vibration of the phone but not LED notification when the screen of the phone is off. Any help is appreciated.

Try to check this thread if it can help you. According to this, You can use a Led notification and choose the color of it. Just add a ledColor field in your notification in the ARGB format array:

{
    "registration_ids": ["my device id"],
    "data": {
        "title": "Green LED",
        "message": "This is my message with a Green LED",
        "ledColor": [0, 0, 255, 0]
    }
}

And here is an example using node-gcm that sends the above JSON:

var gcm = require('node-gcm');
// Replace these with your own values.
var apiKey = "replace with API key";
var deviceID = "my device id";
var service = new gcm.Sender(apiKey);
var message = new gcm.Message();
message.addData('title', 'Green LED');
message.addData('message', 'This is my message with a Green LED');
message.addData('ledColor', [0, 0, 255, 0]);
service.send(message, { registrationTokens: [ deviceID ] }, function (err, response) {
    if(err) console.error(err);
    else    console.log(response);
});
