Qml accelerometer; accelerationMode property not working?

[lockheed]

I am struggling with getting clean (with excluded gravity) readings from qml Accelerometer. It's looks like accelerationMode: Accelerometer.User takes no effects at all ( even onAccelerationModeChanged is not firing). Am I supposed to write c++ Accelerometer wrapper, or algorithm extracting user movement on my own?

Accelerometer{
 id: acc
 active: true 
 skipDuplicates: true
 accelerationMode: Accelerometer.User

onReadingChanged: {
     console.log('acc x', reading.x)
     console.log("acc y", reading.y)
     console.log('acc z', reading.z)
} }

It's a bug, or my fault?

@lockheed just in case, have you tried this example AccelBubble?
In addition could you please provide more details about your environment (OS, Qt version, device where you run app, etc.)

AccelBubble: ball is not moving at all, readings from accelerometer are the same as in my app (z is about 9-9.5, showing gravity acceleration).

Devices:

• Lenovo Tab A7 Android 4.4
• LG k8 LTE Android 6.0

Host os: Win 10 ; Qt: 5.10.1

To show what I am complaining about, there is a small code snippet , modified accelbubble.qml file, which shows current accelerometer readings, and allow to change accelerationMode 'on the fly'. As far as I understand, changing mode from combined, to user, to gravity, should affect readings values.

(besides modified accelbubble.qml, I put
<uses-feature android:name="android.hardware.sensor.accelerometer" android:required="true"/> in Manifest.xml)

My fault. I didn't notice that some hardware backends isn't supporting different accelerationModes. Problem solved.
