Yup. No pairing, and not even an attempt to pair according to the head unit. No error messages from the sketch, no indication that bluetooth is working or not working from its point of view.

I guess I'll have to add some error-checking to the code or something to get this working. Later. MUCH.

EDIT: The only clue: my smartphone did not see the WT32i "on the air" during the entire time it was hooked up to the BGE setup.

Now, with the BT module standalone, it sees it. So, something for me to go on over the holidays!

Cheers
