ST25R3911B-DISCO - activating specific UID

[Ralphie]

I'm trying out the ST25R3911B-DISCO board to evaluate how to read data from multiple 14443A RFID tags. Under the Polling tab I can see all the UIDs for the tags near the board.  However, when I go over to the NFC Type 2 tab, if I select "Configuration" and then "WUPA->Active", the UID field will always be filled by a particular UID.  I can read data from that tag just fine.  How can I activate the other tags so I can read the data on them?  I tried typing a different UID from a nearby tag into the UID field but that just gets overwritten when I click on "WUPA->Active".  

Is it possible to individually read data from any tag that shows up in the Polling scan?

Thanks

Hi Ralphie,

unfortunately this is not possible from this tab.

You could use normal ISO14443A tab using WUPA, then on debug tab issue your needed T2T read commands, go back to ISO14443A tab issuing HLTA, then REQA and then on Debug tab read the memory of the second card.
