T2t Emulsification using ST25R3916

Hello

I want to emulate NTAG215, but I don't think the CE corresponding to T2t is in RFAL. I'm not sure if I understand it correctly, but,

First of all, the status of my code is as follows.
FreeRTOS-based ListenerCylce polling
Emulate nfc context
UID, SAK, ATQA are read, but RFAL_NFC_STATE_ACTIVATED does not seem to receive T2t commands from the reader without a single turn

If necessary, I will upload a portion of the code I am working on.

Help me!

Hi,

the RFAL provides Card Emulation for T4T and T3T on ST25R3916. T2T Card Emulation is not part of the NFC Forum specifications, and it is not an officially supported feature of the RFAL. See https://community.st.com/t5/st25-nfc-rfid-tags-and-readers/st25r3920-t2t-emulation-ack-response/td-p/831340 for a post related to T2T Card Emulation on ST25R3920.
