Synopsis
SDPATTR {link_id} {handle} {attribute}
Description
The SDPATTR command is used to send a Service Attribute Request to a connected SDP server,
identified with the 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 a new SDPATTR command.
The reply contains the response from the SDP server in encoded form. The code characters are
described in Table 7-1.
