does ST have examples of using the new NFCTagReaderSession which works with M24LR16E and up. examples of using NFCISO15693Tag protocol methods: readSingleBlock, writeSingleBlock, lockBlock, readMultipleBlocks, writeMultipleBlocks, getMultipleBlocksSe...
HiI'm trying to communicate from a STM32WB5MMG via a ST25R3916B to a ISO14443-A tag.I use the X-CUBE-NFC6 RFAL library with ST25R3916B, RFAL_FEATURE_NFCA and RFAL_FEATURE_T2T set.Both ST25R self-tests fail:ST25R_SELFTEST returns RFAL_ERR_TIMEOUTST25R...
I am new to NFC. Currently, I have an ST25dv16k NFC. I wrote the EEPROM using the example Arduino code provided in GitHub. I am trying to enable the energy harvesting feature. How will I assign EN_MODE register to 0. Please help.
Hi I am developing a NFC reader design based on ST25R3916B chip. PCB design is in progress. Due to mechanical constraints, NFC antenna would not be in this PCB. So can you pls suggest suitable antenna part number with size more than 50mmX50mm and cab...
Hello everyone, I am currently working on the design of a board that incorporates the ST25R3920B NFC reader IC, aiming to achieve reliable tag detection at a maximum distance of 1 cm. Despite researching and reviewing multiple resources, I am sti...
I'm working on a Flutter project where I need to enable a security session with an ST25DV04K NFC tag by using the Present Password command. However, when I send the command, I receive an unexpected response that suggests the command is failing. Speci...
Dear ST Community,I have just downloaded the software https://www.st.com/en/embedded-software/stsw-st25sdk001.html and I am trying to run the python demo DLL_Demo.py. When I attempt to load the DLL there is an exception: ST25R3911_Dll = windll.LoadLi...
Hi everyone!I’m working with two ST expansion boards:NFC07A1 – ST25DV64KCNFC08A1 – ST25R3916BBefore diving into the communication between these two boards, I tested them individually to explore all their functionalities, and everything worked well. N...
Hello ALL.I am reading this from the ST25DV04KC datasheet:"During the internal write cycle, the device disconnects itself from the bus, and writes a copy of the data from itsinternal latches to the memory cells. The maximum I²C write time (tw) is sho...
I´m tying to load and example project for my nfc kit, which if formed by nucleo-G431RBT board with 25r3916B (nucleo-nfc08A1). I only find projects for another nucleos, so i try to star a new STM32 project (STM32 Cube 1.8.0)starting from my nucleo boa...
