From: Sheldon Demario <sheldon.demario@xxxxxxxxxxxxx>
CreatePairedDevice implements now the same behaviour of CreateDevice,
triggering Discover All Primary Services when needed. SMP negotiation
starts when the link is established. LE capable kernel is required to
test this method properly.
Limitation: For dual mode devices, Discover All Primary Services is not
being executed after SDP search if GATT record is found.
