[Bluez-users] btsco and Jabra Headset

[Bluez-users] btsco and Jabra Headset

[Gunter Ohrner]

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
server: Permission denied
***

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,

  Gunter

Gunter,

something fundamental is wrong if you can find the headset using hcitool 
scan but can't use sdp to examine it. try the command-line sdp scan:

sdptool search --bdaddr <bdaddr> 0x1108

I suspect it will fail but I'm not sure why that would happen. If the 
*connection* was failing, I'd tell you to try removing 
/etc/bluetooth/link_key to reset the pairing. But the pairing is 
irrelevant for sdp queries.

I also tried using a different bluetooth USB stick but this one does not
seem to be supported:

***
CoriCelesti:~# hciconfig hci0 revision
hci0:   Type: USB
        BD Address: 00:11:67:03:D9:89 ACL MTU: 678:8 SCO MTU: 48:5
        Unsupported manufacturer
CoriCelesti:~#
***

So I probaly do not need to make further tests with this one, I guess?

I quick initial test with this stick was not too promising, although the
error message changed:

***
gunter@CoriCelesti:~$ btsco -v 00:07:A4:05:2E:14
btsco v0.4c
Device is 2:0
Error: Failed to connect to SDP server: Connection timed out
Assuming channel 2

Voice setting: 0x0060
Can't connect RFCOMM channel: Resource temporarily unavailable
gunter@CoriCelesti:~$
***

Unfortunately I do not have any different remote USB device to test
against... :-(

Does anyone have any additional ideas of what may be going wrong or should I
post to -devel instead?

Greetings,

  Gunter
