Installation of the OPUSH functionnality on my vaio laptop with debian installed
I could send a file from my pc to the phone (a nokia 6230) but not the oposite
i learn it the hard way : i could not push or send a file from my phone to the vaio debian laptop
in order to do that i had to deactivate the launch of rfcomm in /etc/init.d/bluez-util i
in order to get that command functionning at last :

vaio:/etc/bluetooth# sdptool browse FF:FF:FF:00:00:00
Failed to connect to SDP server on FF:FF:FF:00:00:00: Connection refused
maybe that will break some other stuff around rfcomm i'll report if i find something weird

note : i did not have to activate the OPUSH functionnality by :
$ sdptool add --channel=4 OPUSH
after adding/changing the class variable in /etc/bluetooth/hcid.con
 class 0x100100;
before retrying to launch gnome-obex-server or obexserver i try the tooltip in "Linux Unwired" book after the sdptool trick
$ obex_test -b ff:ff:ff:00:00:00 4
> s
i successfully could send a file from my phone to my laptop :-)

Installation of a bluetooth printer in cups on debian/linux
setup cups, bluetooth, with your default apt-get stanza
configure correctly /etc/bluetooth/printers.conf as

default {
# Bluetooth address of the device
# you obtain that addresse with the command « hcitool scan »
# try « l2ping xx:xx:xx:xx:xx:xx » to check the connection
device 00:40:8C:5E:5D:A4;

# Bluetooth printing protocol
protocol serial;

# Description of the connection
comment "My Bluetooth printer";

then you really have to download the
bluetooth cups package from
cups-bluetooth-0.3.tar.gz  (at the time of this writing)
even if it seems too old for your distrib
and try to compile it correctly
for this you have to edit the configure file
replace libsdp.a reference with libbluetooth.a
and then issue the « regular tryptique »



./make install

but thus last one does nothing
so go to the src directory and copy the newly generated bluetooth file
to /usr/lib/cups/backend
restart cups.... and you now have your printer in
the device list
