Before you start, make sure that:
- you can browse the Internet from your cellphone (take note of the connection profile you use)
- you have a working Bluetooth connection between your phone and the PC
- the devices are paired for connecting without asking for confirmation
- you have bluez-utils emerged with
USE="old-daemons"
Configure a RFCOMM connection with the phone:
- in
/etc/conf.d/bluetoothsetRFCOMM_ENABLE=true - use
sdptool search DUNto find the device's Bluetooth hardware address and the channel on which the cellphone listens for RFCOMM, the scan will take some time - in
/etc/bluetooth/rfcomm.confadd a new connection with the address and channel you just found:
#
# RFCOMM configuration file.
#
rfcomm0 {
# Automatically bind the device at startup
bind yes;
# Bluetooth address of the device
device XX:XX:XX:XX:XX:XX;
# RFCOMM channel for the connection
channel 4;
# Description of the connection
comment "Cellphone GPRS/UMTS DUN";
}
- execute
/etc/init.d/bluetooth restart, you should now have a/dev/rfcomm0device available, andcat /dev/rfcomm0should cause the PC to connect to the cellphone (cat will output nothing, just kill it withCrtl+Cwhen you verify the connection works).
Kernel requirements: besides what is needed for Bluetooth, enable all options under Device Drivers / Network device support / PPP (point-to-point protocol) support. This only adds 16KB to the kernel size. Recompile, install, reboot with your new kernel (or if you really don't want to reboot, compile PPP as a module and modprobe it).
Emerge ppp with USE="dhcp". Create a network service with ln -s /etc/init.d/net /etc/init.d/net.ppp0. Configure it by creating /etc/conf.d/net.ppp0 with the following contents:
### GPRS/EDGE/UMTS configuration ###
config_ppp0=( "ppp" )
link_ppp0="/dev/rfcomm0"
pppd_ppp0=(
"noauth"
"debug"
"local"
"defaultroute"
"usepeerdns"
"lcp-echo-interval 15"
"lcp-echo-failure 3"
"lock"
"115200"
"crtscts"

You'll need to replace "internet" with the name of the connection profile you use for your data transfer (this should be provided by your cellular operator - "internet" is what Plus GSM uses in Poland). Start the connection with /etc/init.d/net.ppp0 start and everything should work.
