[Bluez-devel] Problems connecting to a bluetooth headset

[Bluez-devel] Problems connecting to a bluetooth headset

[Justin Patrin]

I just got a Plantronics Pulsar 260 headset which supports A2DP,
AVRCP, and the headset protocols. I've successfully used it for a2dp
on Mac OS X 10.4 with some hacks[1]. I have also paired it with
various cell phones and tested the headset functionality. However, I
cann't get it to pair or work at all with Linux. I have tested only
with a Linksys USBBT100 USB adapter so far. I will be getting 2 belkin
adapters soon as well that I will try with.

I have tried everything I can think of and searched high and low on
the internet but have found no help. Here's various info which may
help:

Yes, no output with hcitool cc. hcitool conn shows a connection right
after the cc but not right after that. I have tried setting the pin in
/etc/hcid.conf and tried setting the pin_helper to a shell script
which just outputs PIN:0000 (the pin for the headset). The output of
hcitool cc doesn't change whether the headset is in discovery mode or
not. If the headset isn't on hcitool "hangs" and then gives an I/O
error, as I'd expect.

Running a2dpd, with the instructions on the site[2] as a user gives me
binding errors and doesn't respond to Ctrl-C (I have to kill -9 the
process).

The same things happen whether I run these on my Gentoo Athlon system
or my Sharp Zaurus (arm). Both have bluez-utils/libs-3.9 and sbc and
plugz from cvs.

Hi,

The default is not to connect until there is an audio stream.
As long as a2dpd do not connect, the pairing wil not be requested.
Start your media player with pcm.a2dpd as output and 
or try the following commands :
a2dpd_ctl Connect

But nothing will be heard if no media is sent.

Frederic

I did try doing a connect as well but had forgotten that part. Here's
the output from a2dpd when I try connecting.

And nothing was heard except for a few low beeps from the headset. So
it is getting *something*....I'll see if the manual has any info on
what the bleeps and bloops mean.

Make your device discoverable and pairable, you should be asked pairing.
Or install bluez-gnome

Marcel,

> denied)Cannot bind socket 6 for psm 25

I'm wondering what causes this, the bind call is failing with errno=EPERM.
Do you know of something in bluez config or something security related that could prevent binding if not root?

Thanks,
Frederic

"... and run a2dpd (it's not advised to run it as root)."

Hehe. I wonder what the developers do then as it doesn't work as a
normal user.

I got it to work as a normal user, I don't remember exactly what I did, 
but I'm pretty sure that all it needed was a 'chmod a+x' on the required 
files.

I do think that this could be handled better with an /etc/init.d/ script 
that ran a2dpd as the user. Or even hook it into the 
/etc/init.d/bluetooth script.

Yes, I tried that, as I mentioned previously. Nothing happened.

I got bluez-gnome installed and lo and behold...pairing worked. It
looks like bluez doesn't support the default pin any more and requires
a (dbus?) listener to do the pin entry, meaning that bluez-gnome works
but nothing else does.

vlc plays fine through a2dpd now that I've paired. I've also gotten
mpg321 piped to aplay [2] to work, however this isn't a great
solution. mpd refuses to play through a2dpd despite all of my attempts
to make it work. It looks like mpd simply doesn't do alsa well...I'm
trying to debug it with the mpd developers.

Aside from that I found the sound quality horrible.... Playing on my
MacBook Pro [1] with some utulities which I think are derived from
older code from this project, the sound quality is pretty good but
when I used mpg321 and aplay on my Zaurus (arm) with a2dpd the sound
was very crunchy for lack of a better word. Cymbals especially were
very nasty sounding.
