Hi,
I'm doing some research for an upcoming project where I'll need to use
a bluetooth headset for audio (send & recv) with a gumstix. I found the
following two pages:
http://bluetooth-alsa.sourceforge.net/embed.html
http://bluetooth-alsa.sourceforge.net/embedv1.html
which have great information, but I'm curious as to which is the most
current/correct. Specifically, I'm wondering what the current status of
SCO audio with the gumstix (and just on regular PCs frankly) is. I
understand that the blues-alsa project is moving away from btsco toward
plugz, but didn't know how this would affect me on a gumstix.
Any info would be greatly appreciated.
Thanks,
-d

The hciattach etc patches for gumstix are buried in their openembedded
package, but come to think of it that was special case stuff for the
internal adapter. You'll use an external so you should be able to use
the latest and greatest packaging of bluez. That might mean replacing
the gumstix packge with something direct from the OE guys. You might
need to learn more about how OE packages and distros work.
To test things on your laptop, use the docs at wiki.bluez.org to set
up audio. You might be able to use d-bus calls to get the HFP
negotiation you need. It's easiest to prototype that stuff in python
using the examples in the wiki.

Brad,
Thanks for the pointers. I was getting a little confused WRT what was the
current best path. Where can I find info on the hciattach patches, etc? I
don't recall seeing anything about that in my searching.
I figured I'd have to use a different BT module, so I'm working with
prototyping on a laptop until I get my gumstix gear together. I need to
figure out how to use the HFP to get handsfree device events, and I figure
that may take a bit of time.
Thanks again,
-d

The best option is to use the most recent bluez version you can and
use the built-in audio service it provides. btsco and plugz are both
dead ends. There is a little bit of hackery you'll have to do with eg
hciattach which has patches that can't go upstream. See the gumstix
openembedded package for details. Make sure you ask the gumstix folks
because I believe they have a newer bluez than the default one you get
in their openembedded environment.
As far as hardware, if you're not using a prototype of the next
gumstix board then you should add a bluetooth USB adapter that has a
CSR chip in it to a verdex board. The integrated bluetooth module has
not been used successfully for SCO.
