M24SR64 NFC IC and peer to peer (p2p) communications

[Vandermyer]

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.

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.

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.

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