Hello, I am working with X-CUBE-NFC6 example and I am able to read and write data to a rfid tag successfully. Just as a note, hw configuration is nucleo U083RC boards with NFC08A1 expander board for rfid reader. I would like to be able t...
Hi There, I am developing a product where I need to remotely wake up my electronics from 0.5-1.5 m, and also read back some user information about the unit I just woke up (e.g. serial number, firmware version the MCU is running etc). It needs to be a...
Hello, I am planning on implementing a ST25R3916 circuit starting from X-NUCLEO-NFC08A1 schematic, but LXRW0YV600-054 is marked EOL for 2026. Is there any recommendation for change of the implementation? Thank you! Best regards, Dragos
Hello!I'm completely lost in my search for a solution.Question description: The 25R3916 in 14443A emulation mode. When sending data to the reader with a length of up to 255 bytes, everything works perfectly. However, if I need to send data longer tha...
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, ...
Hello,I recently purchased the STEVAL-25R3916B board and it functions correctly with the out-of-the-box demo. However, I’ve been unable to get it working with any of the available software tools, such as the ST25R3916 Discovery GUI or ST25-PC.I’ve c...
Hello,Can this chip produce a constant [unmodulated] NFC field without timeout? I have a lab application where I'd like to output a constant unmodulated signal through attached NFC antenna. Based on reading the datasheet a direct command can be use...
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...
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 (...
