How to get RSSI value for P2P communication.

[ELTE-TakeC]

We checked the P2P communication and was successful in communicating between ST25R3918 and ST25R3916B.

Is it possible to measure the P2P RSSI in the same way using rfalGetTransceiveRSSI()?

In the case of NFC tags, we can get the RSSI based on the call back timing, but with P2P, we can't get it, so please let me confirm.

We use P2P demo is available in the ST25 embedded NFC library (ap2p_proprietary folder). and NUCLEO-L476RG .

Hi,

In AP2P both sides are doing reader-style modulation of their own field. To my knowledge the card-style receiver (to decode reader modulation) does not contain RSSI feature.

Hi,Thank you for reply. My description seems to be limited to certain timings, but is there a way to obtain the information at times other than the Call Back timing?

Hi,

not sure if I get your point. RSSI can retrieved any time after the reception before the next transmission.
