We programmed the ST25DV16 tag using the antenna and the GUI using the ST25R3919B. However, when we use the android apps to read the ST25DV16 tag its not getting read. The android apps read all the other tags of 13.56 mHz available in the market, but...

Listener has a inductance of 750nH, so we made this schematics. There is an additional 180pF in parallel to the charging coil.

Hi, We used this to design our antenna https://eds.st.com/antenna/#/As the antenna was small with 12mm x 7mm we could achieve only around 500nH of inductance. However we could use the two ICs (poller - ST25R39 and listener ST25DV) to charge the devic...
