Bluetooth Service Discovery Agent Overview

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.

CSdpAgent is used to make Symbian OS Bluetooth SDP requests to a remote device. There are two basic queries you can make using it:

• Getting the services on the remote device and setting the classes of service for which you want to query using a CSdpSearchPattern object

• Getting the attributes for a specific service and setting a list of attributes to be retrieved using a CSdpAttrIdMatchList object

An application using 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.

The following tutorials will help get you started using the Bluetooth SDP Service Discovery Agent.

• Querying the SDP database

• Reading remote SDP service attributes
