Hello,
we've got a new problem while collecting data from a bunch of RFID readers.

Our setup is made by many RFID readers, most of them sending data with a rate of 1 sec x antenna (data from 4 antennas every 4 secs).
Rfid tags data are parsed through the LLRP plugin module and passed to the expression plugin module, which reformats data before sending them out via mqtt.

We have observed that in some cases the data parsed are null, as you can see in the section of logs file, attached to this email.
Beside to the correct data you will find some null data in the following form:
NewTagEvent[1]=*NULL*

We did not have this issue in the past, when the active rfid readers were about 6.
Today we have switch on about 50 rfid readers, with the same data rate, and we are seeing that the issue is quite frequent.

Could the high data traffic and data acquisition rate be the cause?

Could you please help on this?

Thank you for your support

Kind Regards,
Andrea

Hello Arthur,
ok, I see.
Actually this does not disturb me, but since in our project we are going to have a huge data traffic (more than 30 RFID readers, each with 4 antennas, trasmitting the tags report every second) we are working to optimize each data report, removing any redundant info. Since we don't need the port info, DATA_SOURCE_NAME is enough for us and we don't need both info.

By the way, I though it was easily removable by any configuration.
Since it is not, this is not a big issue for us.

Thanks again,
Andrea

Hello Arthur,
I mean the rfid tags report.
In the file llrp-init.xml there is no reference to the DATA_SOURCE_FULL_NAME to remove it from the report. Is there any other way to remove this parameter from the data received by the RFID reader in the tags report?

Thanks a lot,

Hello,
I'm using Advanced TCP/IP Data Logger to get data from a RFID reader.
I would like to remove the variable DATA_SOURCE_FULL_NAME from the tags report.
Is it possible? If so, how to do?

Many thanks,
Andrea
