Hi everyone,
this is my first message in LTK newsletter, despite I've been using java
LTK for a long time.
My question is mostly related to LLRP protocol rather than LTK itself.
Anyway, I hope you can answer my question.
On EPCglobal LLRP standard I read: "FirstSeenTimestamp: The Reader SHALL
set it to the time of the first observation amongst the tag reports that
get accumulated in the TagReportData", and similarly for the LastSeen.
But I'm not able to have different FirstSeen and LastSeenTimeStampUTC
values in my TagReportData Objects. They have always the same value. I
think I have some misconfiguration in my ROSpec, but I can't really
understand.
My goal is to know when a tag enters and leaves the antennas ranges,
knowing that the tag transit is quite fast (up to 3 seconds).
Can you help me in configuring my ROSpec? Which type of start/stop triggers
have I to use in both ROSpec and AISpec ?
Thank you,
Roberto
