Hello,
I think I didn't asked my question "the smart way", so I try to do it
now:
I already searched the internet and asked in forums, but I didn't find
an answer to my question. And I have to say that english isn't my native
language, so I hope you understand what I try to say.
The problem is that since I installed BlueZ-4.99 and the sspdebug mode
patch, my connection via "pand"-command doesn't work (With BlueZ-4.98 &
without this patch it worked!)
I have two gentoo-PCs and try to connect this way:
PC2 # sdptool add NAP
PC2 # pand -s -r NAP -M
PC1 # pand -c <bd-address>
You find the whole hcidump message down below in this email. It looks
like a security block problem. But I don't know how to change my
security configuration. I found this file:
/usr/src/linux/include/net/bluetooth/bluetooth.h
and uncommented this line:
define BT_SECURITY_LOW 1
But this dind't helped.
So I hope you can tell me how I can set up my security configuration
appropriately or something else to get this pand-connection worked.
Thanks and best regards,
Steffen
