[Bluez-devel] Problems connecting to a bluetooth headset

["Justin Patrin" <papercrane@gmail.com>]

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.
