Hi Michael,

now I get what you want. In general adding SDP records with sdptool is
only for testing purpose. You should include you own code for it, like
we do for pand or dund. However if you think that the add_headset() in
sdptool misses an attribute then fix this and send in a patch for it.

Regards

Marcel
