I have the ST25RU3993 UHF RAIN RFID evaluation board.
I have some YARONGTECH Impinj H47 860-960MHZ Monza 4 915M EPC C1G2 ISO18000-6C UHF RFID tags.
With the antenna supplied I can interrogate the tags and sometimes see the TID displayed. However, if I place 2 tags near the reader antenna there doesn't seem to be a consistent read count of both tags. Sometimes only 1 TID is displayed with the read count continuously incrementing. I would expect to see 2 distinct TIDs on a reliable basis, but I don't see that behaviour with the ST25RU3993 kit.
Is there a reason for this behaviour ? Is there something that I can do to get 2 consistent, reliable TIDs displayed when I place 2 UHF tags close to the reader field ?
Thanks,

Hi Ian,
which GUI version do you use?
Please use our latest release 1.7.0, this solves a lot of SW issues.
As you can see, it is possible for me to read the TID of two tags easily.
The Monza 4 tags are fine. We do not have any issue with a certain tag IC type.
Here are the reader settings:
Best regards,

Marcel,
Thanks for sending through your answer. I had another reply from Bernhard with some suggestions on the Q.
I am away from my base for another couple of weeks, then I will repeat the test and capture the results. I don't get the same results as displayed on your screenshots. I can potentially see 2 tags but it is very hit ad miss, which doesn't seem right.
Let me run it again, I am using software GUI version 1.7.0.0. Not sure of the hardware firmware version. I can check that once I return to base from my travels.
Regards,
Ian
