Hello list,

with this posting I publish a software that mimicks a Bluetooth HID
(keyboard and mouse combo device) on a Linux PC. Thus you can
remote-control other Bluez-equipped PCs, Widcomm-stack equipped windows
boxes, and basically any machine that knows how to talk to Bluetooth
keyboards in non-boot-protocol mode.

Source code is GNU GPLd, and can be found on
http://www.hoffmeister-online.de/bluez/hidclient-20060725.tar.bz2

Short instructions (for root users):
Download the file and unpack it
# wget -q
http://www.hoffmeister-online.de/bluez/hidclient-20060725.tar.bz2
# tar -xjvf hidclient-20060725.tar.bz2

Run make and copy the hid-sdp-record.bin into /etc/bluetooth/

Make sure bluez is installed (else the "make" will most probably fail
anyway) and the SDP daemon is running (which it should by default).

Change to a Linux textmode console (e.g. Ctrl+Alt+F1) and run
./hidclient
from there. Then, startup the other machine and discover the "HID"
service available on your virtual-HID box. Connect to it.

Move the mouse, touch the keyboard, enjoy.

Hint: The bluetooth connection can be interrupted by pressing "Pause",
the program can be aborted altogether with LeftCtrl+LeftAlt+Pause

Beware, all keyboard and mouse input will simultaneously be read by your
virtual-HID computer as well! That's why running hidclient from a
textmode console is a good idea.

Code history: Developped as a practical work during the "Networks"
course at Rheinische Friedrich-Wilhelms-Universit=E4t, Bonn, Germany in
2004/2005 for the Nokia-supported, GPLd, Affix Bluetooth stack.
Ported in July/2006 to bluez, several code cleanups and improvements.

Questions welcome.

Regards
Anselm
