Hi @zjhon.1 (Community Member)​ 

the NFC Forum Activity specifications defines Card Emulation for TA4, T4B and T3 types. Our rfal_nfc convenience layer implement the card emulation for those types as defined by the NFC Forum.

If I well understand you need, you would like to emulate something close to T2 with additional proprietary commands. In my understand is correction, I would suggest to follow the recommendation provided by Ulysses HERNIOSUS to hack the T4T Card Emulation case in rfal_nfc.

Feel free to provide more information about your application and your use cases.

Hi @zjhon.1​ 

an example of card emulation is included in the X-CUBE-NFC6 firmware package as part of the pollingTagDetect project. Both T3T and T4AT card are emulated. In the pollingTagDetect, the ST25R3916 loops between reader/writer mode and card emulation mode. If only card emulation is needed, the demo can easily be modified.

Feel free to share more details about your application and use cases.

If this is answering your question, would you please mark this answer as the best so that it is marked as resolved.

Hi  @zjhon.1​ 

Can you elaborate on the non-standard protocol? is the anti collision also non standard or is the anti-collision compliant with ISO14443-A ?

I mean, is the non-standard protocol only used after the card enters ACTIVE state?

Can you confirm also that only ISO14443-A modulation is used?

Thanks

在命令的开头和传输中,有一些�?�标准�??议;

大多数�?然是标准ISO14443-A,包括防撞;

我肯定是 Iso14443 - A 调制
