The value of this property represents the unique identifier of the peer. The first time a local manager encounters a peer, the system assigns the peer a UUID, represented by a new
UUID object. Peers use
UUID instances to identify themselves, instead of by the
CBUUID objects that identify a peripheral’s services, characteristics, and descriptors.
