Hi all,
I have a device with address 00:09:1F:80:12:21, i can pair the device
to Bluez, the linkkeys file contains:
# cat /var/lib/bluetooth/00\:07\:80\:56\:F8\:70/linkkeys
00:09:1F:80:12:21 41F80F349B12603669616D178B0F5974 4 0
from hcidump, the "Link Key Request Negative Reply" is received, then
"Unauthenticated Combination Key" is received, then "Connection
refused - security block" is received.
Is this a Bluez or device problem? There is a "Fix l2cap conn
failures for ssp devices", is it related?
Thanks,
Victor

It looks like a BlueZ (kernel) problem.

Yes, I think that patch should fix the issue.
