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.

Hi,

which FW do you use:

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,

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?

Hi,

for being able to reproduce:

Please send a picture of the card
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?
Is your system able to read other cards?

Regards, Ulysses

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
