SDP involves communication between a SDP server and a SDP client. The server maintainsa list of service records that describe the characteristics of services associated withthe server. Each service record contains information about a single service. A client mayretrieve information from a service record maintained by the SDP server by issuing a SDPrequest. If the client, or an application associated with the client, decides to use aservice, it must open a separate connection to the service provider in order to utilizethe service. SDP provides a mechanism for discovering services and their attributes, butit does not provide a mechanism for utilizing those services.
Normally, a SDP client searches for services based on some desired characteristics ofthe services. However, there are times when it is desirable to discover which types ofservices are described by an SDP server's service records without any a prioriinformation about the services. This process of looking for any offered services iscalled browsing.
The Bluetooth SDP server sdpd( and commandline client sdpcontrol( areincluded in the standard FreeBSD installation. The following example shows how to performa SDP browse query.
% sdpcontrol -a 00:01:03:fc:6e:ec browse

... and so on. Note that each service has a list of attributes (RFCOMM channel forexample). Depending on the service you might need to make a note of some of theattributes. Some Bluetooth implementations do not support service browsing and may returnan empty list. In this case it is possible to search for the specific service. Theexample below shows how to search for the OBEX Object Push (OPUSH) service:
