As Brad already wrote, dig bluetooth.org. The whole BT thing is set up
as a standard (sort of), from hardware up to the software/driver level.
You can find everything (i.e. AT commands) in the core docs. Maybe you
have to check the older BT specs (1.1) for the headset profile and
especially the sco stuff. And make sure to understand what the different
transport layers do, it helps a lot.

good luck :)
