I checked again the log file showing on tag report, and I can verify that
all the related commands (ADD_ROSPEC, ENABLE_ROSPEC, START_ROSPEC,
ADD_ACCESSSPEC, ENABLE_ACCESSSPEC) have been sent to the Rifidi
successfully and they all received the success response, but with report
trigger set to ROSpecTrigger=0 and AccessReportTrigger=1, there are no
tag reports.
What caused me to be suspicious of the report trigger settings on Rifidi
was that we run the same test again with Rifidi simulator but with the
report trigger set to ROSpecTrigger=1 and AccessReportTrigger=0, we got
tag reports in this test.

Re: [Rifidi-developers] Problems using the AccessSpecReport trigger.
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.
