Get heart rate sensor data on Android Wear

Question

I am trying to get the heart rate sensor data on my Android Wear device (Moto 360). But I don't know why the TYPE_HEART_RATE is not recognized, and the app says sensor registered: no. Other types like STEP_COUNTER returns yes.

What is the problem?!

public void onCreate() {
        super.onCreate();
        // register us as a sensor listener
        mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        Sensor mHeartRateSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_HEART_RATE);
        boolean res = mSensorManager.registerListener(this, mHeartRateSensor,  SensorManager.SENSOR_DELAY_UI);
        Log.d(LOG_TAG, " sensor registered: " + (res ? "yes" : "no"));

        mGoogleApiClient = new GoogleApiClient.Builder(this).addApi(Wearable.API).build();
        mGoogleApiClient.connect();
    }

We should go to the smartwatch's Settings-->Apps-->[App Name]-->Permissions in order to check if that permission is enabled. It's disabled by default!
