Allows a local service to register itself to a local Bluetooth service database. This enables remote Bluetooth devices to discover the service doing an SDP Agent search.
The Service Discovery Database API is one of two APIs that allow you to use the Bluetooth Service Discovery Protocol. The other, the Bluetooth Service Discovery Agent, enables you to discover the Bluetooth services, and the attributes of those services, that are available on a remote device.
A client must create and connect a session,
RSdp
, and a subsession, RSdpDatabase
,
to access the database. A subsession allows service records and their
attributes to be added, updated, and deleted.
A service is described through a number of attributes, each of which can hold a specific type of value, such as an integer, boolean, string, etc.
The base class through which all attributes are manipulated is
CSdpAttrValue
.
A family of classes derived from CSdpAttrValue
provide classes through which these types can be manipulated:
CSdpAttrValueBoolean
,
CSdpAttrValueDEA
, CSdpAttrValueDES
,
CSdpAttrValueInt
, CSdpAttrValueNil
,
CSdpAttrValueString
,
CSdpAttrValueUint
, CSdpAttrValueURL
,
and CSdpAttrValueUUID
.
Two classes, CSdpAttrValueDEA
and
CSdpAttrValueDES
, enable lists of attributes to be constructed.
Both implement the MSdpElementBuilder
interface that
provides functions to accumlatively add attributes to a list.
The attributes for a service are stored in a service record. A record
is referred to through an ID, known as a service record handle, stored in a
TSdpServRecordHandle
.
Start with the Service Records and Attributes guide.
The following tutorials explain how to get started using the service discovery database.
