Bluez / Bluetooth Docs

Bluez / Bluetooth Docs

[Richi Plana]

Hi,

My apologies in advance for the slightly off-topic post.

Working under the assumption that one can't bind two BT headsets to one
BT adapter (device or whatever the correct term is), I've made available
two BT adapters on my notebook (one USB dongle) and am now trying to
pair one headset with one device. The problem is I've no idea how this
works outside of the automagic that Fedora does (using hcid).

My question is where can I find documentation that covers the concepts
behind bluetooth on linux, specifically the bluez implementation. I've
checked out www.bluez.org and downloaded the latest packages, but they
don't contain documentation on how things are supposed to work (which
daemons or utils do what).

Are there official docs available that explains the infrastructure and
tools to a newbie? If not official, could someone point me out to a good
set of docs that might get me on my way?

Thanks.

Any pointers? Other mailing lists? IRC channels? There's nothing on the 
bluez website.

Not that I've tried it, but I expect that this assumption is wrong - you 
can talk to multiple bluetooth devices with one transceiver, and I don't 
see any reason to expect headsets to be a special case?

For access via ALSA I have, for my one headset:
pcm.bluetooth {
        type bluetooth
        device "00:13:A9:C2:43:41"
}


You might have some success putting two such entries into your .asoundrc 
(you might have a pcm.bluetooth1 and pcm.bluetooth2, and obviously you 
need to enter the two device addresses for your headsets).  I do this 
under BlueZ 4.x, so it might be different in your case.

Then this kind of thing should work: mplayer -ao alsa:device=bluetooth1 
play.mp3
