Hi Everyone.We are using ST25R3918-AQET in our product. But this IC shortage in recently, so we want to find an Alternative part that can match with ST25R3918-AQET and doesn't change anything related to FW or PCB design.We appreciate your support in ...
Can anyone point me at an RFID/NFC solution from STM? I'm looking for a product that would ideally fall between the NXP PM532 family of 'All-in One' non flexible transponder solutions and the Ti TRF7970 family of very flexible but complex transceiver...
Hello ST Team,I am currently working on a project that integrates the ST25R3916B NFC reader, and I would like to study and reference the PCB design of the X-NUCLEO-NFC08A1 evaluation board.Could you please provide the Altium Designer project files (....
Hi! I am trying to control the read write permission of my st25dv nfc tag with a nordic chip, but i am having a hard time doing that. I am able to write to it and everything using i2c and nfc, and with the following code #include <zephyr/kernel.h> ...
Hi all, I’m using an ST25R3916 with RFAL on an STM32 and I’m trying to talk to an NXP NTAG 5 Boost (ISO15693/NFC-V) using its custom commands: READ/WRITE SRAM (0xD2/0xD3) and READ/WRITE I²C (0xD5/0xD4). Plain ISO15693 commands work fine (e.g., Read...
I am using a NUCLEO-L053R8 board with an X-NUCLEO-NFC08A1 extension. I made modifications to the NFC08A1 to enable I2C communications and this works. I can read the A bank of registers and the values all make sense except for IO configuration registe...
hi,I want to implement nfc tag that detect iphone and send message that shoing on iphone screenhave someone that implement this logic?i start to implement some code and i detect the phone but not received data of APDU command from the phone.have hav...
Hi everyone,I'd like to use the ST25R3916B device for a very low-power device. I downloaded the X-CUBE-NFC6 library version 3.0.0, and I don't see an example of calling rfalLowPowerModeStart().I saw earlier that someone managed to find it in version ...
Hello, I use st25r3916 driver and DemoCycle from X-Cube-NFC6 app but devCnt for discovery is never more than 1 even though I have 2 tags next to the antenna and devLimit is set to 3. Also I see state machine never goes to RFAL_NFC_STATE_POLL_SELEC...
Dear Colleagues, Dear STM Team,I use an ST25R3911B, and when I connect to the tag, I send data there and everything is fine. The problem occurs when I hold my phone with the eCard for payments to it. It then attempts to pay with a card over the phone...
