Oh, well USB is ok too i guess, but i run the bluetooth daemon on my
laptop, and start sdpd and dund with the option "--listen call dun"
A kind of like how they describe it on
http://wiki.openmoko.org/wiki/Manually_using_Bluetooth, but than on the
laptop instead of the FR.
(search for "PPP <http://wiki.openmoko.org/wiki/PPP> and a DUN
(dialup-networking) emulation mode." on that page)
on the FR i simply run
export BLUEMAC=ED:ED:ED:ED:ED:ED # *your* laptop's bluetooth device goes
here
rfcomm release /dev/rfcomm0 # just to make sure
rfcomm bind /dev/rfcomm0 "${BLUEMAC}" 1
pppd /dev/rfcomm0 call dun
echo 1 > /proc/sys/net/ipv4/ip_forward
/etc/ppp/peers/dun contains the details for you bluetooth connection
like IP addres, dns etc.
i knitted some scripts around it on om2008.12, with x message, so i can
just click BT -> on to set up the connection or BT -> off to termintae it.
But that is just cosmetics/handy.
Hope this helps.
Kind regards,
Ed
