Hello,I'm using RFAL v2.6.0 and ST25R3911B and I get an issue with the IRQ management.Using ISO14443 Type-A tag, the IRQ remains high causing the while loop not to exit. In this condition, the i_err bit of the main interrupt register is '1' while th...
Currently, only smartag_WriteData is downloaded from ST official installation package, but I need to store NDEF data, I have noticed that NFC07A1 has NfcTag_WriteNDEF, then how should I add NDEF read/write function in FP-SNS-SMARTAG1?
Hi I'm trying to write some data in to ST25dv64 NFC TAG using custom mobile application, before writing data into NFC tag we are encrypting message. encryption method is AES 128 CBC, the encrypted message has some non-printable characters, like 0x91,...

wanted suggestions on SW integration to handle 2/3 NFC03A1 boards with RPi4HW SPI connections seems to be okon the SW side, how to handle multiple spi.Pls advise
pls suggest a example for reader/writer/formatter for NFC03A1are there any writer example code for RPi similar to poller example ?https://community.st.com/t5/st25-nfc-rfid-tags-and-readers/x-cube-nfc3-for-stm32cube/td-p/591339i didnot find the source...
Hi to all, I'm starting a new project with ST25R95 and X-NUCLEO-NFC03A1 as demo board. I have two question about example usage:1) I can't find X-CUBE-NFC3 package in cube MX (only 4 and 6 are avaiable). How can I add this package to Cube MX configura...
Writing 256 bytes ( full mailbox message ) failes when using I2C in DMA mode. I think the max is 255, correct me if I am wrong.Any way I can write it using 2 messages safely? Or am I restricted to non-DMA I2C write only?
Hi Team,How strong is 8 bytes NFC password given the fact that there is no lockout mechanism. Assuming an attacker with physical proximity tries to brute-force (try all combination) the password on nfc chip, How much time will be needed to crack the ...
With the ST25R3916, how can filtering of the 3rd harmonic (40.5 MHz) be improved? Following the procedure outlined in AN5276, a matching network was made. Performance of the device was verified, and emissions in the 13.56 MHz band are within FCC limi...
