Is it possible to use breacham.obex api in order to change a name displayed(to device) when a push operation is started?

If I understand that you want to send a file but with a different filename, then just supply the new name as the name parameter to PutFrom.  For instance

   Using(src As FileStream = File.OpenRead("database\card.vcf"))
      sess.PutFrom(src, "my business card.vcf", null, src.Length)
   End Using

I wish to change bluetooth device name..

Err, I don’t understand…  What is the name for?  Is the receiving device name, or the sending device name?  And where is this name to be displayed differently?

Scenario:
PC with bluetooth dongle send a message to a cellular.
I want to change the PC name displayed in a cellular display.

Ahh, ok.  No I don't think that there is anything OBEX can do to affect that behaviour, there's no OBEX Header related to that area.

I presume that when the receiving device discovers the sender it queries it for its name at the Bluetooth level, and when the transfer starts it displays that name.  Of course, in Windows XP the Bluetooth Devices applet allow one to manually rename a remembered device but I guess that's not the side you want to do the renaming from.
