It's pretty much plug and play.
Default PIN for accessing your bluetooth device will be 1234. This and some other stuff can be changed by editing the configuration files in etc/bluetooth
I nice thing to have is the obexpush command, which you can finally use to send files to other bluetooth devices. Receiving such files just works fine too.
Now all I need is a gui obex tool. Unfortunately I am a Delphi guy with no idea about Zaurus programming....
