[Bluez-users] btsco and Jabra Headset

[Gunter Ohrner <G.Ohrner@post.rwth-aachen.de>]

Hi!

I've had a hard time trying to get my headset working but had no success so
far. :-(

I've found single report on the syptoms I get on the net
(http://www.linuxforen.de/forums/archive/index.php/t-182494.html), but
unfortunately no solution/follow up posting...

I'm also happy abaout RTFMs, maybe I missed something - these are my first
steps with bluetooth.

I'm running a vanilla 2.6.11.11 kernel with all those bluetooth drivers
compiled as modules. (Further systems details can be found at the end of
this mail.) The bluetooth USB stick is recognized and driven by the ohci
driver, so it's probably no ehci issue...

These are the symptoms:

***
# btsco -v 00:07:A4:05:2E:14
btsco v0.4c
Device is 2:0
Error: Failed to connect to SDP server: Permission denied
Assuming channel 2

Voice setting: 0x0060
Can't connect RFCOMM channel: Permission denied
CoriCelesti:/usr/src#
***

This happens no matter if I run it as root or my normal user. (which is in
group dialup, all the /dev/rfcomm1 belong to group dialup) The btsco is a
CVS checkout from yesterday.

The bluetooth dongle:

I already tried to delete /etc/bluetooth/pin and to write the default pin
into it, to no avail.

strace says btsco fails during a connect call:

***
connect(4, {sa_family=AF_BLUETOOTH, sa_data="\1\0\24
\5\244\7\0\0\0\0\0\0\0"}, 10) = -1 EACCES (Permission denied)
close(4)                                = 0
write(2, "Error: ", 7Error: )                  = 7
write(2, "Failed to connect to SDP server:"..., 70Failed to connect to SDP

***

Are there any obvious mistakes or does anyone have any hints? As I said I'm
new to this whole bluetooth technology so maybe I'm missing something
really obvious... :-/

I really appreciate any help!

Greetings,
