[Bluez-users] connecting 2 linux pc's

["g.starre" <info@microllix.nl>]

Hi all,
  
After a long time trying, I still cannot connect
2 linux PC's together using usb-bluetooth sticks
with rfcomm.

I'm using among others :
knoppix 3.7 CD boot (bootoption knoppix26)
debian PC (2.6.11-rc4-bk10 kernel, unstable dist)
debian laptop (2.6.11-rc4 kernel, unstable dist)

All the modules like
- hci_usb
- rfcomm
- bluetooth
- l2cap
are loaded either by the kernel (/etc/modules) or
by hand using modprobe.

These command's are used to try to setup
a connection :

hciconfig hci0 up
sdptool add sp
rfcomm bind 0 <bdaddr> 1
rfcomm connect 0

While on the "receiving" debian laptop these command's
were issued :

hciconfig hci0 up
sdptool add sp
rfcomm listen /dev/rfcomm0 1

To check connection I use cat/echo (or minicom)
-> echo "hello world" > /dev/rfcomm0

This way I can connect to a pc with some proprietary OS,
but I cannot build a connection between 2 linux pc's.

Yesterday I was able to start a connection between
a debian PC and debian laptop but immedeatily after
pressing the return button on the debian PC the
laptop responded with (rfcomm listen /dev/rfcomm0) :

 Press control-c to disconnect
 Disconnected


It's probably one bit I have to toggle ;-)

Some settings in hcid.conf :
pairing multi;
lm accept;
lp rswitch,hold,sniff,park;

My rfcomm.conf on the debian PC is
modified like this :
rfcomm0 {
  bind yes;
  device <bd-address of debian laptop connected BT dongle>;
  channel 1;
}

The service was restarted each time the config
was altered with /etc/init.d/bluez-utils stop
and then ..... start

In all the howto's/archives there is a lot of
info how to connect to a phone or some device,
but there's no info how to connect 2 pc's.
Can anyone help ?

Thanks in advance.


grt, geert
