Sorry for the delay in replying. Had to run some tests.
On newer versions of Windows, Windows assigns 2 COM ports for Bluetooth Classic connections. One for receiving and one for sending.The dropController uses a single COM port for send and receive which means it is not possible to use Bluetooth with Windows 8/10 at this time.
On my desktop I have a BlueSoleil Bluetooth dongle which creates a single COM port and so works with the dropController.
I will look in to what is required to update the dropController firmware to accommodate 2 COM ports but cannot say how long this may be or if it is possible.
