9.5.3 S

DPATTR

The SDPATTR command is used to send a Service Attribute Request to a connected SDP

server, identified with link_id. The command supports requesting for one attribute value

(specified with the attribute parameter, 4 hex digits, or a keyword) in one (previously

retrieved) service entry (specified with the handle parameter, 8 hex digits), but several

requests can be sent during the same SDP connection. However, you must wait for the reply to

the previous reply before issuing new SDPSEARCH command.

The reply contains the response from the SDP server in encoded form. The code characters are

described in Table 8.
