You're using several third-party libraries here. I don't know which module you're actually using, but you'll need to check their documentation. InTheHand certainly has a BluetoothLE scanner similar to their regular Bluetooth scanner.
Microsoft also has BLE support built-in. You don't really need the third-party libraries:
