	protected boolean isOptionalServiceSupported(@NonNull final BluetoothGatt gatt) {
		return false;
	}
This method should return <code>true</code> when the gatt device supports the
optional services. The default implementation returns <code>false</code>.

@param gatt the gatt device with services discovered
@return <code>True</code> when the device has the optional service.
@deprecated Use {@link BleManager#isOptionalServiceSupported(BluetoothGatt)} instead.
