Hello,
I still have a problem to connect my bluetooth devices via pand
command. I've been searching the internet and asked in forums, but i
didn't get an answer.
I have 2 gentoo-PCs with a Bluetooth-3.0 Dongle at each PC.
Circa 2 weeks ago, everything worked. BlueZ-4.96 was installed and I
had no problems to connect my devices via pand and via rfcomm command.
But then I asked you for an SSP debug mode patch, because I wanted to
sniff my rfcomm connection. At the same time BlueZ-4.99 was released
and so I installed the new BlueZ-version and the patch.
I also deleted the stored linkkey and I was happy that I was able to
sniff my rfcomm-connection.
But thenceforth I can't connect my devices via pand command.
Then I tried to install the BlueZ-4.99 *without* the patch, but I
still couldn't connect via pand.
I also tried to install BlueZ-4.96, but the problem was still the
same. So I think it's no problem of the patch or the newer
BlueZ-version, but I really have no idea what's wrong.
If you need any of my configuration-files, just tell me and I will
send it.
In the end, I show the hcidump message when I try to connect via pand
command.
Hope anyone can help me.
Regards,
Steffen

That's still my problem, but now I have a different question regarding
to that:
As I said, I deleted the stored linkkey to get my rfcomm-connection sniffed.
Now I think this (deleting the linkkey) is the problem why I can't
connect via pand. Am I right?
With "deleting" I mean: I just deleted the file "linkkeys" in
/var/lib/bluetooth/<local-bdaddr>/
So my question is: How can I create a new linkkey (so that hopefully my
pand-connection works) ?
I tried the command "hciconfig hci0 putkey" but nothing happened.
I also tried to copy a backup-file ("linkkeys"-file) into both of my
/var/lib/bluetooth-folders, but it looks like the devices don't use the
key from that backup-file.
Regards,
Steffen
