Hi,
I have a pair of A2DP speakers and I am trying to pair them with a USB bluetooth adapter on Fedora
8 with a 2.6.25.4 kernel (bluez-libs,utils 3.31, bluez-gnome 0.26):

However, my attempts to pair these speakers with my adapter are all failing because the connection
is being dropped before I can authenticate. This is what strace says about my "auth" command:

I know that there's nothing wrong with the speakers because I also have a laptop with a built-in
bluetooth adapter (also F8, 2.6.25.4 kernel), and this has managed to pair with and them use the
speakers without difficulty. I can also use l2ping between my USB adapter and my speakers, despite
them not having paired:
# l2ping 00:14:EF:00:20:05
Ping: 00:14:EF:00:20:05 from 00:0A:3A:7D:FF:80 (data size 44) ...
4 bytes from 00:14:EF:00:20:05 id 0 time 7.73ms
4 bytes from 00:14:EF:00:20:05 id 1 time 22.91ms
4 bytes from 00:14:EF:00:20:05 id 2 time 21.68ms
4 bytes from 00:14:EF:00:20:05 id 3 time 20.44ms
4 bytes from 00:14:EF:00:20:05 id 4 time 19.24ms
4 bytes from 00:14:EF:00:20:05 id 5 time 11.01ms
...
However, this seems to be as much as I can do until they have bonded. (In fact, the only way that
I could keep the connection alive long enough to strace the "auth" command was by using l2ping.)
Does anyone have any suggestions for anything else to try, please?
Cheers,
Chris

it is, but you have to start hcid with -x. Also passkey-agent.c is
part of the bluez-utils source and within /usr/share/doc/bluez-utils
in Debian.

Brad can you sent me the script or binary of the passkey-agent tool,
because I don't have it in my distribution (debian-sid) and my python
dbus simple-agent script is not able to registration it self anymore.
Thanks in advance,
Jelle

I had a pairing & timing problem like this with an at&t tilt. It might
work for you to log out of the machine and from the console, run
passkey-agent --default 0000 &
then attempt the connection using command-line tools (like aplay in your case).
