yes... it should be possible to reset the bluetooth adapter to use cpu
(hci) routing. I haven't tried this (and it gets a little scary for
bricking, etc) but the command to temporarily make the change and
reset the adaper looks like:
bccmd psset -r 0x1ab 0
this may only take after running it twice.
a better option for testing out hci routing would be to turn off the
internal bluetooth adapter and attach a csr-based usb adapter to the
miniusb port. If you've got a good adapter, after plugging it in you
should be able to run:
hciconfig hci0 revision
and see "SCO mapping: HCI"
then you can follow the instructions that apply to using voice
bluetooth audio on a desktop machine. getting the gsm call to route
over it will be another hurdle--it's why I asked in another thread if
it's possible to record gsm calls.
the kernel support for doing hci-routed audio is vastly better in the
latest kernel using the btusb driver. That driver may still be in
flux.
