Thanks for helping! It shouldn't need to be this complicated though, so I'll see what I can do. Knowing that the BT pairing needs to be done in order for my driver to work is useful information, but means I'll have to do a larger change to my driver to access the board using Bluetooth rather than the COM port provided. Now I know why Lars does that in his driver! It's not the end of the world as I do it for Certabo already.

But can I ask everyone using this for a favour? Can you run my ComPort program and go to the Bluetooth tab, and then see what Channel it says the Millennium uses. I think it will be 6, but if you have different Channels then I will need to add some extra, slower, searching code to locate it each time.

Meanwhile, my change shouldn't have broken the USB connection. It means that my assumption about what works on one type of board board will work on all of them was wrong! I can easily adjust that and should be able to release a fixed version 2.5.1 in the next day or two.

Thanks!
