ORA-1 Magnetometer found ?

[stephassoria]

Hello,

    using android API we have this code :

Log.i("sensor", "magnetometer : " + sensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD));
ok = ok && sensorManager.registerListener(sensorEventListener, mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD), SensorManager.SENSOR_DELAY_FASTEST);

in the logcat we have :
magnetometer : {Sensor name="MPL Magnetic Field", vendor="Invensense", version=1, type=2, maxRange=9830.0, resolution=0.285, power=10.0, minDelay=10000}

So one magnetometer seems to be found, but in the listener if we log event values like this :
Log.i("sensor fusion", "magneto : " + event.values[0] + ", " + event.values[1] + ", " + event.values[2]);

we always get {0,0,0}.

   
So when we tried to use the sensor type "Sensor.TYPE_ROTATION_VECTOR" :
sensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR);

the initialisation is OK (no error), but the returned values are corrupted as magnetometer return 0 values.
   
Is ORA-1 really have a magnetometer (not specified on hardware specs) ?

What's the good way to retrieve gyroscope data ?

thanks

DEar Mr Capo,
I think we have replied to you directly through direct technical support & email exchange and by checking your Glasses functionality, fo which we have changed the MPU and now it works.
