How to use CR95HF demo board with ISO14443-A tags? Only works with ISO15693. Making python wrapper for C library for linux user for CR95HF, with demo board. Detects ISO15693 tags but not 14443-A tags... Also read_block doesnt seem to work...

[IEdwa.1]

CR95HF datasheet: https://www.st.com/resource/en/datasheet/cr95hf.pdf

Demo board: https://www.st.com/en/evaluation-tools/m24lr-discovery.html#documentation

C/C++ library and guide for demo board: https://www.st.com/resource/en/application_note/dm00134778-cr95hf-c-library-for-linux-user-stmicroelectronics.pdf

Dont fully understand datasheet, but used SendReceive to read and write. Wondering how to get it to work with 14443-A. Windows demo software doesnt work for 14443A tag on demo board.

Hi,

Which ISO14443-A tag (manufacturer & model) do you use?

Can you check that the tag is functional by using for example an Android phone + nfc app such as ST25 NFC Tap?

Using the CR95HF Development Software, menu Tools-> Toolbox, can you share the following informations:

• MCU Revision
• DLL revision
• HW version
• IDN

Can you confirm the board is MB1054B?

Regarding 'Windows demo software doesnt work for 14443A tag on demo board', can you share the log ?

On my side, I can detect ISO14443-A tags:
