When I try to add my bluetooth keyboard, it shows up during a scan and then instantly disappears. Running btmon shows this output: http://sprunge.us/aAjV. Of interest is the following:
< ACL Data TX: Handle 12 flags 0x00 dlen 16 [hci0] 24.073197
L2CAP: Connection Response (0x03) ident 7 len 8
Destination CID: 65
Source CID: 67
Result: Connection refused - security block (0x0003)
Status: No further information available (0x0000)I'm having major difficulty getting this to work. It worked fine before a recent update, but I can't find exactly what broke.

This is the output from bluetoothd when this error happens:

I ran bluetoothd under strace to see what file it was looking for (grepped for ENOENT), and it was looking for /var/lib/bluetooth/<adapter mac>/<keyboard mac>. Why would it not just automatically create those directories? Why does bluetoothd think they should exist? Is there somewhere else that bluetoothd stores information other than /var/lib/bluetooth?

Did you try with another bluetooth device ? android or bluetooth speakers ?
What about another bluetooth manager ? try blueman.

Using a different frontend doesn't help, since the error happens without using a bluetooth frontend at all. All I have to do to reproduce the error is run bluetoothd and hit the pair button on my keyboard.
My guess is that there's something saved somewhere that makes bluetoothd think that the keyboard shouuld already be paired, but I've cleared out /var/lib/bluetooth, and I'm not sure of anywhere else where it might store data. I've also cleared out /etc/bluetooth (and have restarted, rebooted, etc).

Other bluetooth devices seem to show up fine, that is, they don't disappear immediately during the scan.

Ok, I figured it out. Chalk this one up to confusing errors in bluetooth that lead me down the wrong path. With the apple wireless keyboard, you apparently have to hold the button down for more than 30 seconds before it completely resets and goes into pairing mode.
