Advice on starting BT project

Sorry for cross-posting, but I feel pretty sure that this
belongs in
the user's list rather than the  devel list. I'm really new
to this
mailing list thing and this is my second post...


I am seeking some advice on a class project that we are
planning.  We
would like to create a system that can emulate AVDTP/A2DP to
the point
that you may play MP3 from Windows Media onto a Bluetooth
device.

Does anyone have definate suggestions on how to proceed?



Here's my plan thus far:

  >>  Obtain a Bluetooth module that implements up to
the HCI interface.
I would like to also have the L2CAP and SDP modules in
hardware, but
this does not seem to be available as such. Any modules that
do
implement these seem to also force you to use the SPP module
(LMX9830
for example).

  >>  Port an early version of the Axis stack to a
dsPIC microcontroller.
I am most familiar with the dsPIC and its tools. From what I
gather,
the Bluez/Linux kernel driver use threading and
Linux-specific code,
so it is easiest to port from the original Axis release.
Also I prefer
this approach to a full-fledged embedded Linux for cost and
complexity
reasons.

  >>  Tack onto the driver the bare minimum to
establish a connection and
initiate streaming.
The Core, AVDTP, and A2DP specifications are quite detailed
and I have
become familiar enough with them that I believe this is
possible,
given the correct interface to the lower levels.

you're not getting feedback because on the bluez lists we
discuss
bluetooth on linux using the bluez stack. We're only
touching on other
stacks when it comes to making them interoperate with bluez.

the app "a2play" (see bluetooth-alsa.sf.net) will
play audio to a
headset with only an l2cap interface from the os.

if you want much more help i'd suggest you lie and say
you're using linux.

Thanks for the tip! Any idea where I could go for
implementing/porting
the Bluetooth stack to a microcontroller?
