Hi,

I think I have a working 'bluepin' script (the one which is responsible 
for the PIN entry GUI during pairing) for SuSE 9.0, which hopefully 
addresses all the problems several folks have suffered from in the last 
weeks. The Script is attached to this note.

I have made the following changes to the script from 
http://bluez.sourceforge.net/download/bluepin:

- moved the "import gtk" statement behind the "set_display ()" call
   (as this is the case in the current script in cvs).
- replaced the "if arg[i][0] != '-' and i==1:" line with
   "if i==1 and arg[i][0] == ':':"
   (as proposed by Jean-Marc Autexier
    http://www.autexier.de/jmau/linux/Bluetooth.html
    and others)

Furthermore, the following packages need to be present on the SuSE 9.0 
box (which are normally not installed):

- python-gtk (bindings)
- python-numeric

These changes may apply accordingly to earlier versions of SuSE Linux, 
too (I have observed similar problems with 'bluepin' in SuSE 8.x, too).


Maybe someone out of the BlueZ community may put this script on his web 
site for the public (my institute home page won't live very much longer).


Cheers,

Michael
