Thank you for your fast answer.

I am not quite sure about the security mode the device is. How can I get 
it? In any case, I have executed (as root):

$ hciconfig hci0 noencrypt
$ hciconfig hci0 noauth

but still no success. With the same computer and configuration and as a 
normal user, if I send a file from KDE using kbtobexclient, it works as 
expected (no PIN requested, just the confirmation for receiving the 
message), so I believe that there is some other things to do. I guess 
that it should be a library call or somthing similar. Any suggestions?

Thanks,

Pedro
