Hi,
STSW-ST25R-LIB - ST25 embedded NFC library provides additional demos (with project files for STM32CubeIDE) whereas X-CUBE-NFC6 provides only polling and ndef demos for Keil µVision, IAR EWARM and STM32CubeIDE.
If you use X-CUBE-NFC6 you can continue with it except if you need one of the demos provided in STSW-ST25R-LIB - ST25 embedded NFC library.
The default polling demo supports by default the various technologies. So by default, Type V support is enabled.

Hello I have tried with different card of type A ST card but still not able to detect the card .
Also inside democycle code
case DEMO_ST_DISCOVERY:
if( rfalNfcIsDevActivated( rfalNfcGetState() ) )
This fucntion returns state RFAL_NFC_STATE_LISTEN_COLAVOIDANCE always.
Is there any macros need to be changed in the code ?

Hi,
Can you probe the field with an oscilloscope? ( just connect the ground wire to the tip of the probe (building a loop) and put it in free air close to the tag antenna)

Hi,
well, once the field is ON, a very nice 13.56MHz sine wave should be seen on the scope.
Can you set a breakpoint inside rfalFieldOnAndStartGT and step until the return and then probe the field.

Hello
I have recently purchased 2 boards out of which one is working but another is not.
I have tried to check with another board (nucleo-nfc08a1) it is working properly the nfc cards are getting detected. but with another board as you suggested i tried to check inside rfalFieldOnAndStartGT function but still same wave is coming.

Hi,
I would suggest to return the defective board to your reseller and to ask him to send you a new one.
