Android BLE Error 0x06 Request Not Supported

Question

My app is facing issue while connecting to BLE device. On every connection attempt app makes, it gets Error code 0x0006(Request not supported) in OnConnectionStateChange() method. I have tried Bluetooth OFF/ON but still getting same error.

I am facing this issue in LG D410(Android 5.0.2). After I upgraded my LG phone to 5.0.2, app started getting this error. My app is working fine with Samsung Galaxy S4(Android 5.1), Nexus 5(Android 6.0).

Why am I getting this error? What can be done to fix it?

Here is the logs of error:

I think there is an issue in BlueDroid framework in Android Lollipop versions. if you use connectGatt(Context context, boolean autoConnect, BluetoothGattCallback callback) pass autoConnect = false;

making autoConnect true causes abnormality in onClientConnectionState in Lollipop version, however, works appropriately in Marshmallow.

I made it work.

@Override
protected void onStart() {
    super.onStart();
    Log.d(TAG,"connecting Gatt");
    bluetoothGatt = bleScanResult.getBluetoothDevice().connectGatt(this, false, callback);
}


@Override
    protected void onStop() {
        super.onStop();
        if (bluetoothGatt != null) {
            Log.d(TAG,"disconnecting Gatt");
            bluetoothGatt.disconnect();
            bluetoothGatt.close();
            bluetoothGatt = null;
        }
    }
