M24SR64 NFC IC and peer to peer (p2p) communications

Hi All!

I hope this is not too much of a dumb question, but does the M24SR64-Y NFC IC (on the b-l475e-iot01a evaluation board) support peer-to-peer NFC comms.?

If it does, is there any library code to assist in this? The code in en.stm32cubel4_v1-18-0 doesn't seem to support p2p (or have I missed something?)

Thanks.

Hi,

M24SR64-Y is a dual interface tag device supporting I2C and NFC RF interfaces. As far as I know, the RF communication cannot be tunneled to the MCU through I2C and thus peer-to-peer is likely not supported.

Peer-to-peer is supported on ST25R3916/16B reader devices and a demo of a simple P2P exchange between 2 ST25R3916/16B boards is available in the ST25 embedded NFC library.

Feel free to share more details about your application so that we can better support you.

Hello @Vandermyer 

You can use the NFC functions in this drive to create your application ( I can't find a ready to use exemple for P2P).

Best regards.

Thanks for those replies. Both seem to confirm what I thought - P2P not possible with the M24SR64-Y NFC IC.
