Tag not detected with X-NUCLEO NFC08A1

[cGosa.1]

I am using X-NUCLEO NFC08A1 dev board & NUCLEO-L476RG base board with STM32 IDE. I want to detect NFC card on eval board but currently the card is not getting detected. can you please help to solve this issue.not able to receive data on serial port also.

Hi,

which FW do you use:

• X-CUBE-NFC6
• or STSW-ST25R-LIB - ST25 embedded NFC library

What is the return code of st25r3916Initialize?

Do you see LEDs blinking forever?

Have you configured your serial terminal for 115200, no parity, 8 bits, 1 stop bit?

I am using X-CUBE_NFC6. the leds are not blinking forever only once in the start they blink also TX LED pin keeps blinking.

I have configured serial port it shows initial Initialization succeeded message on serial terminal.

bit card is not getting detected.

Hi,

which tag do you use (manufacturer / model)? Can you try to read it with your smartphone using the ST NFC Tap application?

Hi ,

I am using ST microelectronics - ST25V02K Card.

Hi,

please share more information. ST25TV02K is the name of the chip. But what is the actual card? Something from ST tag bags? Which one? Your own produced?

Did you verify the card is working by some other means? Maybe broken?

Regards, Ulysses

Yes it is from ST tag bag it is a Type V card. I have checked the card works with other hardware .

Hi,

for being able to reproduce:

1. Please send a picture of the card
2. I read you are using NUCLEO-L476. Inside the package is a precompiled binary for that combo. Does it happen with this binary as well?
3. Is your system able to read other cards?

Regards, Ulysses

Hi,

can you try to read other types of tags (such as NFC-A or NFC-B tags)?

Have you done any changes to the X-CUBE-NFC6 original code?

Can you probe the field with an oscilloscope?

ok i will check with other type of card meanwhile I have  STSW-ST25R-LIB - ST25 embedded NFC library also what exactly is difference in X-CUBE-NFC6 and other.

Also are there any other configurations required in example code because I a first time using NFC08A1 development board and STM32 IDE. So do let me know

[Brian TIDAL]

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)
