Hi, I am using a customer board with h7. Similarly, I want to read a simple nfc card using the st25r3916 chip. For this, I made the necessary adjustments using RFAL libraries without using the cubeMx ready package.I have completed the necessary hardw...
Hi, We are developing a prototype containing a st25r3916b nfc reader. When the prototype is idle it goes into sleep mode and wakes up through the wakeup function. When we actively poll for a card from our MCU we can read a UID from a distance of abou...
hi, I have some code for reading/writing to a mailbox from the ST25R3916B transceiver to a ST25DV64KC tag. The read passes but the write fails every time;its errcode is ERR_PROTO;My code is following:static void demo2Nfcv(rfalNfcvListenDevice *nfc...
Hi everyone,I'm currently working with the X-NUCLEO-NFC08A1 expansion board and using the ST25R3916 NFC reader IC with an STM32L010RB microcontroller.When I call rfalNfcInitialize(), the initialization process fails and enters the error handler. Aft...
Hi,I am designing an NFC reader based on the ST25R3916B for a payment interface, ensuring compliance with EMVCo standards. For hardware development, I am using the ST25R3916B-EMVCO reference design as my baseline.Queries:Custom NFC Antenna Design:I p...
I have RFID reading with ST25R3911 working now with RFAL and I would like to sense if there is a RFID tag nearby before starting RFID reading. I did not find any example code in RFAL. I looked into data sheet and tried to read the registers:st25r391...
Hi all !I need to know is it possible to communicate (data transfer) between ST25R3916B and Mobile application for both Android and iOS is possible or not.If yes I need to know by which type of NFC communcation I can able to acheive and If there is a...
I am Using ST NFC tap app on an Android phone .I am using STm32L053 to communicate with ST25DV64KC board.I can send the data to ST25DV64KC through I2c read write and have enabled mailbox .Now when I tap the tag with mobile I can see on mobile that m...
We are using an ST25R3916B to read and write to both ST25TV512C tags and Mifare Classic 1K cards. While we have successfully communicated with ST25 tags, we are encountering issues at the authentication stage with Mifare Classic.Steps We Are Followi...
Hello all,I discovered that selecting in STM32CubeIDE under Pinout & Configuration/Middleware and Software Packs/ X-CUBE-NFC4 the source folder Middleware/ST/lib_nfc is added to the project source tree, containing the source files for the lib_nfc lib...
