I am trying to get the Battery Level from BluetoothDevice in Android 8.1.0 of remotely connected BT device.

BluetoothDevice mBTDevice = (BluetoothDevice) bundle
                        .getParcelable(BluetoothDevice.EXTRA_DEVICE);
int val = mBtDevice.getBatteryLevel();

But its val always returning value as "-1" . It seems not working in Android 8.1.0

Got the info from this link

From your link, "(or -1 if Bluetooth is disabled, the device is disconnected, or does not support reporting its battery level)" – MikeOscarEcho Dec 03 '18 at 20:57
Not all devices support this. What device are you connected to? – thi gg Feb 13 '19 at 08:02
