Puck.js ADV_IND does not contain the sensor value

Hi

I'm testing the ADV_IND associated to a sensing service definition as follow

NRF.setServices({
	// Configuring the Envrionmental Sensing Service
	0x181A: {
		// Configure Temperature Characteristics
		0x2A6E: {
			readable: true,
			notify: true,
			writeable: false,
		}
	}
});
NRF.setAdvertising(
   [
	{0x181A : [Puck.light()]}], 
   {interval:500}
);

I've controlled that the service is well defined into the GATT
I receive ADV_IND perdiodically as expected

My problem is that the Service Data value does not change at all. Egal to 0 !!
I've check several things

The Puck.light() is Ok as the following code works fine

setInterval(function() {
  print (Puck.light());
}, 500);

I've tried to replace the Puck.light() by

- new Float32Array([Puck.light() * 100]).buffer or
 - new Int16Array([E.getTemperature() * 100]).buffer

The value is not = 0 but does not change neither ..

Any idea ?
Other option to get this sensing value ?
