Does the NFC support RATS?

[Manlio]

Hi,

We want to use the NFC of nrf52 to develop a payment card. And we will use RATS to exchange data, does the NFC of nrf52 support this? Is there any code or lib or example in the SDK for us?

Thanks!

Hi

Please check out the ISO-DEP protocol in the nRFConnect SDK which is a library providing implementation for an NFC polling device.

The function nfc_t4t_isodep_rats_send sends a RATS command according to the NFC digital spec, and is used by the reader/writer to negotiate the maximum frame size and the bit rate divisors with the Listener.

Best regards,

Simon
