Enables you to discover the Bluetooth services, and the attributes of those services, that are available on a remote device.
The Service Discovery Agent API is one of two APIs that enable you to use the Bluetooth Service Discovery Protocol. The other, the Bluetooth Service Discovery Database, enables a local service to enter its own properties into a local service database.
The central class for making Bluetooth service discovery protocol (SDP) requests to a remote device is CSdpAgent. There are two basic queries you can make using it:
to get the services on the remote device, set the classes of service for which you want to query using a CSdpSearchPattern object
to get the attributes for a specific service, set a list of attributes to be retrieved using a CSdpAttrIdMatchList object
A user of CSdpAgent must implement the interface MSdpAgentNotifier to receive the responses to queries.
The API also supplies CElementParser, to parse a raw input buffer containing an attribute value into its constituent data elements.
