Hi!
As the feedback I got in -user@ suggests that it may not be
misconfiguration, I'm now posting here as well, with updated information.
Any pointers to further documentation are greatly appreciated. As I'm a
complete bluetooth newbie I may well have missed some vital information
required to get everything running.
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...
The same problem happened with vanilla kernels 2.6.9 @i386 and 2.6.11.11
@AMD64, the bluetooth drivers were compiled as modules in both cases. I'm
suing a CSR USB bleutooth stick as recommended, driven by the ohci-hcd
drivers as I read about possible problems with the ehci ones.
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
`----
This happens no matter if I run it as root or my normal user. (which is in
group dialup, all the /dev/rfcomm* belong to group dialup) The btsco is a
CVS checkout from few days ago.
Even using sdptool directly fails badly:
,----[ sdptool search --bdaddr 00:07:A4:05:2E:14 0x1108 ]
| Class 0x1108
| Failed to connect to SDP server on 00:07:A4:05:2E:14: Permission denied
`----
Although the bluetooth stick seems to be detected correctly and finds the
headset when scanning for it:
,----[ hcitool scan ]
| Scanning ...
| 00:07:A4:05:2E:14 JABRA BT200
`----
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

I'm I missing some reqiured kernel support here?
