    LLRP Custom Extensions

    Seckin Can

      Hi,

       

      What does "Tag Visibility Changed EventType" in MotoTagEventEntry custom parameter mean?

       

      Does it mean tag is visible now or not visible? How can we know that?

       

      Thanks

          Hi,

           

          The "Tag Visibility Changed" event is triggered in autonomous mode, when a tag enters or leaves the field of view. It triggers either way. The event triggers a default RO spec. A new inventory round is cunducted and the tags in the field of view are reported. This prevents too much redundant data from being polled off the reader, when the tag population in the FOV doesn't change frequently.

          A flow diagram for both modes (Host based LLRP and autonomous) are described in detail in chapter 2 of the RFID Reader Software Interface Control Guide.
