I'm trying to pair my nokia 770 with my desktop which is
running fc6t2, kernel-2.6.18-rc4. bluez-libs-3.0. Using a
zonet usb dongle.
The 770 returns a "no services" message. On the desktop,
/var/log/messages:

That was it. Once I sdptool add FTP , pairing succeeded,
without any kernel error messages.

I can't say anything about the desktop side problems, but the reason you
get "no services" is that the 770 will only pair with devices that have
either a Dial-up Networking (DUN) or OBEX File Transfer profile service
records (or both) in its SDP server. So if you e.g. do a "sdptool add
DUN" and "sdptool add FTP" on the desktop side you shouldn't get that
error message.
