B.1.18 Get SDR Command
This command returns the sensor record specified by ‘Record ID’. The command also accepts a ‘byte
range’ specification that allows just a selected portion of the record to be retrieved. The Requester must
first reserve the SDR Repository using the ‘Reserver SDR Repository’ command in order for an
incremental read to an offset other than 0000h to be accepted.
If ‘Record ID’ is specified as 0000h, this command returns the Record Header for the ‘first’ SDR in the
repository. FFFFh specifies that the ‘last’ SDR in the repository should be listed. If ‘Record ID’ is non-
zero, the command returns the information from the matching record, and the Record ID for the
next
SDR in the repository.
