Problem rw on ST25TV02KC ISO15693

[FBena.1]

I'm using a DLP-RID2 device to write and read data in a ISO 15693 TAG, in particular i'm using tags based on the ST25TV02KC which have 320 bytes of information arranged in 80 blocks of 4 bytes each.

My problem is that with a new factory TAG, i can't read block 50, and read/write operations don't works.

Do you have any suggestions for any commands to use to be able to use all 80 blocks?

I attach a log that illustrates the commands sent for a read

Best regards

Hi,

I think you need to increase the address to be read in hexadecimal like this: 00 01 02 03 04 05 06 07 08 09 0a

Your last successful reading is from address 0x49=73 and then with 0x50 you are jumping to 80 which doesn't exist anymore.

Hi Ulysses,

thank you for the response.

You are completely right!

I fixed the requests by asking in hexadecimal and it works.

Thank you so much for the very useful tip!

I think we can close this topic.
