[Bluez-users] Problems pairing with phone

[Jonas Häggqvist]

I'm having problems pairing my phone and laptop (eventually to be used with
gammu). I'm using the version of bluez and utils currently in Ubuntu
"Gutsy" (development version). I installed bluez-gnome, dependencies and
some other bluez-related packages such as hcidump. I set up the dongle
using the GNOME bluetooth-applet and everything looks fine so far.

However, when I attempt to search for devices from my phone, it finds
nothing, and hcidump sees nothing during the search.

Any help would be appreciated. The phone and dongle has previously been
paired in Windows (using MS bt stack), so the hardware should not be the
problem.

The device is set up as follows:

This is what the phone tells me:

While running "sudo hcitool cc 00:18:C5:88:FC:0A" I get the following
output from hcidump. The phone briefly flashes "ISJTAR" as an active
connection, then disconnects (I can't quite figure out what cc is
supposed to do - maybe it's not expected to do anything):
