SL2S2602 - Single Block with blocked for write

[MacFiore]

Hy everyone. I am working with the SL2S2602 tag using the PN5180 controller. I was able to read, write, put in Privacy mode, change Password, using Datasheet information. However, I'm trying to block for writing in just a few tag blocks that I know is possible, but I'm not able to get the sequence of commands. I am basically doing the following:
1) Unlock tag:
- Get Random,
- Set Password [02h, B3H, 02h, 04h, .....] (Using Standard Password 0x00, 0x00, 0x00, 0x00) -> In this condition I have an unknown error reported.
2) Write Single Block.

Reading repeatedly the datasheet was the impression that it would be necessary to use block 79 (16 bit counter) to do this. However, I do not find information on how to assemble the sequence of writing and blocking only one block of the tag. Can you help me. Thanks.

Hello @MacFiore 

Thank you very much for your interest in using our products.
There is a document could be available for you (AN11138 - ICODE SLI/SLIX/SLIX2/DNA Memory Access Management).
But as you know, this is a secure product, and the documentation requires an NDA. If you already have one, please go to https://www.docstore.nxp.com request for download. In addition, there is an example (SW352233\Examples\Nfcrdlib_SimplifiedAPI_ISO) also could help you. This is open-source code and development based on pn5180.
As a friendly reminder, NDA related issues are not appropriate for discussion in the forum, if you have questions, please ask the below link. Thank you for your cooperation. Have a nice day.
