st25r100 alternatively in Tx Mode and in Rx Mode

Hi all,

I am working on the ST25R100 which I would like to be able to read  a NFC tag but also to be read by a Smartphone.
Is it possible to do it simultaneously or at least alternatively by switching one mode to the other?
If yes what could we switch modes in less than a second?
Is there some example code which is doing this?

Thank you,

Sylvain

    Hi sguitton,

    not sure about your question: ST25R100 does not support card emulation: This means you cannot swap roles by e.g. having smarthphone acting as reader. Even if so, it would get hard to get to 1s switch time on the phone.

    But if ST25R100 is acting as reader and the smartphone is running an App with a registered AID then this offers you a bi-directional communication channel.
