Hi everyone,I’m currently working on integrating the ST25R3916B NFC reader into my custom hardware and would like to avoid implementing the complete driver from scratch in C/C++. Therefore, I’m trying to base my work on the X-CUBE-NFC6 software packa...
Hello everyone,I am currently using a custom NFC board based on the X-Nucleo-NFC08A1 that has the ST25R3920B MCU. I am able to perform OOB pairing (LE Secure Connections) using the example provided by ST in the software tools example. I can sucessful...
Hi,I would like to know if it is possible to use another oscillator source other than a crystal for the ST25R300?I saw another post for the ST25R3911B, Is it possible to use a Clock Oscillator instead of Quartz crystal oscillator?, although obviously...
The X-CUBE-NFC3 zip I downloaded (v2.1.0) does not contain the CR95HF driver (Drivers/CR95HF folder missing). The package claims to support CR95HF for STM32, but only ST25R95 files are present.Impact:Cannot detect ST25TA tags using X-NUCLEO-NFC03A1 (...
I have X-Nucleo-Nfc09A1 and Nucleo-L053R8. I am trying to test the kit with X-CUBE-NFC9 software. But it gets stuck with this error:if( !st25r200CheckChipID( NULL ) ) { platformErrorHandle(); return RFAL_ERR_HW_MISMATCH; }Post edited to apply s...

Hello ST Community,I've been exploring STEVAL-25R200A dev kit using the X-CUBE-NFC10 package-based sample application. Currently, I am testing the UNTRACEABLE mode feature in the ST25TV tag. However, I’m noticing some unexpected behavior and would lo...
Hi Team,I have purchased the STEVAL-25R200SA board. I would like to know if I can develop custom NFC features using this board. And please provide me with sample NFC application code suitable for this board to refer to. Thank youSreevishakh
the document said, the correction factor is due to skin effect, but the K formula seems make a mistake (inverted). should it be Rp@fwork/Rp@fres = K = √(fwork/fres) instead, so the value is incorrect too?(as for skin effect, with frequency increase, ...
