Orientation Sensor not working

[MyEcho]

Hi,
Has anyone tried using the Orientation Sensor?
I haven't been able to get the sensor to work.

Would love some sample code if possible.

Thanks heaps in advance,

Echo

The accelerometer?

Thanks Allan for your reply.

I've got the Accelerometer working.  I'm talking about the OrientationSensor API.
I'm trying this as there also seem to be problems with the Gyroscope as well.

Ooo...I didn't realise there was such a thing!

Same happens to me:

const orientationSensor = new OrientationSensor();
setInterval(() => {
	console.log(orientationSensor.readings);
	if (orientationSensor.readings) {
		const { quaternion } = orientationSensor.readings;
		console.log(quaternion);
		if (quaternion) {
			console.log(quaternion.join());
		}
	}
}, 1000);

Prints forever:

Hi Sergius,
Sorry for taking so long to respond, busy days.
I'm working on the orientation sensor these days.  Once I have more information I'll share here.

Hi,

any news?

Thank you.

Have you tried the example in the sensor guide?  

It uses onreading plus it starts the sensor orientation.start() which it needs for operation otherwise you are just reading an empty record.  Also it sets the interval so you should not need to use setInterval().

import { OrientationSensor } from "orientation";

let orientation = new OrientationSensor({ frequency: 60 });

orientation.onreading = function() {
  console.log("Orientation Sensor Reading: " +
              "timestamp: " + orientation.timestamp,
              "quaternion[0]: " + orientation.quaternion[0],
              "quaternion[1]: " + orientation.quaternion[1],
              "quaternion[2]: " + orientation.quaternion[2],
              "quaternion[3]: " + orientation.quaternion[3]);
}

orientation.start();
