I have a trouble connecting my Nokia 3610 cell phone via bluetooth link.
as Iain already asked :) what exactly are you trying to do?
are you trying to put/get something to/from your phone (for example
pictures, ring tones, etc)? if so, then use comm/obexapp from ports.
are you trying to use your phone as wireless modem to connect your
laptop to the net? if so, then you should be using rfcomm_pppd(8) in
_client_ mode and connect to dun (or lan, if your phone supports it)
service on your phone. another option is to use rfcomm_sppd(8) in
_client_ mode and ppp(8). basically use
set device "!/usr/bin/rfcomm_sppd -a BD_ADDR"
in your /etc/ppp/ppp.conf and use something similar to rfcomm-dialup
example mentioned in the rfcomm_pppd(8) man page.
