Hi,

I had bluez + ubuntu hoary making a ppp connection over bluetooth to
my 6630, just fine for a few days, by following the instructions here:

http://www.teaparty.net/technotes/blue-gprs.html

and then suddenly it broke.

now, when I do
'pppd call gprs', it just returns, the phone never prompts me to
accept the connection, and no connection is made.

it seems to be communicating:

 rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 clean
root@stefvaio:~ # pppd call gprs
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 config [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 config [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 config [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 config [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 config [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 config [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 config [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 disconnecting [tty-attached]
root@stefvaio:~ # rfcomm show
rfcomm0: 00:12:62:DC:EA:63 channel 1 closed
root@stefvaio:~ #

but it doesn't seem able to make the connection anymore

I did a couple of things (overexcited by the ease with which I got it
working), that might have caused this.

I tried to re-pair the phone with the laptop, because I wanted to
change the name of the phone.  So I deleted the pairing on the phone,
and then the /etc/bluetooth/link_key . Now when I re-pair, it finds
the device, but just hangs with 'waiting for stefvaio-0', and then
'says unable to pair' . The phone still works fine with another
machine running OSX (and I realise you can change the name without
re-pairing. woe is me)

so it looks like pairing is the cause of the problem.

How do I re-pair the phone with my laptop, short of reinstalling everything? 

where should I  be looking for further diagnostics?

I also changed my hcid.conf to try and get my palm sync working too,
so that may have caused the problem.

I have attached the hcid.conf in case it's glaringly obvious.

This is a shame. I've waited *years* for my phone to become a decent
access device, and then after a weekend I've broken it.
