No worries. It doesn't hurt to ask, and it's nice to know for sure.
Not to argue with you, but it seems that Andy figured it out somehow. I've only used a couple bluetooth adapters, but they worked pretty well. Given the number of people around the world with all kinds of bt adapters, and very few problems among them, it doesn't appear that the hardware is such a big issue.
That said, I understand this is a VERY low priority, and I'm happy with that. There are many other things I'd like to see in RCS before ThrottlePro support. I just wanted to get this one on the board, so to speak.
