Service Discovery Protocol (SDP) is a protocol that allows Bluetooth devices to discover the services that other Bluetooth devices are willing to share.
SDP only allows the discovery of services on the server device that the client device can handle. This is unlike other protocols/technologies like JINI that go further - allowing the client to use the services on the server without knowing anything about the service beforehand.
In short - SDP is no more complex and has no more functionality than the Microsoft Windows registry. The differences are in the query methods and the communication medium involved.
SDP communicates directly with L2CAP, so it is independent of the protocol being used for any application level communication such as TCP/IP.
You must be really bored if you want to read these, so I haven't included them.
