Yes, that's exactly how I understood your earlier post.

But that does not give me any clue on how to use D-Bus either. I've seen 
through the D-Bus specification, but it does not define anything 
BlueZ-specific and I couldn't find anything related to D-Bus on the 
BlueZ.org or Holtmann.org pages. Again, I have no clue on where to start 
learning about specifically the BlueZ D-Bus interfaces - what path and 
properties etc I can use with D-Bus to access the information we need.
