With lots of help from Thomas I have updated my Millennium driver to support BluetoothLE connections in Arena, LucasChess and Shredder. This can be used in Windows 10 (from version 1703 onwards) but you might need to install a Visual C library. Details are in the ReadMe file included in the download:

I finally got a board to test with and found that the display of the LEDs on human moves wasn't very reliable so I have fixed that, as well as providing an option to say if the board has been rotated (used when setting up positions). And I changed the LED pattern for take back moves as I found using just one LED on each square wasn't easy to use.

Please let me know how you get on with the BLE connection as it's my first driver using this technology.

Thanks,
Graham
