Reading a block from NTAG 5 using NFC Cockpit Tool

amighri — Wed, 08 Dec 2021 08:21:09 GMT

I would like to know the difference between read Block ISO15693 in NFC Cockpit and reading a block using a Read command C0 . Enclosed I tried to read the same block A0 but I get different answers ? You can see the result I get in the Image. The reader I'm using is PNEV7462C.

Thanks in Advance

Greetings,

Hello Amighri,
As the Datasheet mentioned in section 8.1 Memory organization, the memory is organized in blocks, these blocks contain 4 bytes. The larges number, as is mentioned in the NFC Cockpit is 256. Typically, these blocks aren´t protected and are the ones that contain the NDEF message among other information.
On the other hand, the read command can interact with the protected memory files that can be created and modified in the T5T device. And they aren´t limited to 256 but, to the whole memory of the device. In this case to the 2048 bytes.
My apologies for the delay in answering.

I hope this information may have been useful.
