Adam,
I think the problem may have to do with the Access operation itself
rather than the reporting. I went back and checked the logic of
reporting, and it appears that the Rifidi LLRP reader does allow you to
set the ROSpecTrigger=0 and the AccessReportTrigger=1 and receive
reports only after an access spec has executed.
So I think the reason that you did not receive a RO_ACCESS_REPORT as
expected is because the access spec never executed. I did find one
minor bug though: if you used the SET_READER_CONFIG message to set the
reporting mechanisms instead of setting them in the ADD_ROSPEC and the
ADD_ACCESSSPEC messages, you would not have received reports back.
However, because you were setting this information in the latter
messages, I think the reporting should have worked.
I have included the ADD_ROSPEC, ADD_ACCESSSPEC and RO_ACCESS_REPORT
messages from a test that I ran for you to look at.
