We are using application which get low frequency audio signal from HFP BT point. We have used Android version 3.xx which work fine. and the BT point was define as headset point When we have upgrade the android version to 4.xx the BT point is define as audio phone and the low frequency are being cut out. We didn"t find anyway to define the BT point as headset.
- Is there any way to define BT point as headset in android 4.xx
- Can we upload the Android 3.xx BT stack to android 4.xx
thanks
