I have two Nucleo boards, both NUCLEO-L476RG. The first board is equipped with the X-NUCLEO-NFC08A1 (ST25R3916B), while the second board has the NFC 5 Click board (ST25R3918).I am trying to establish peer-to-peer (P2P) communication between these boa...
Hello!We are using ST25R3916B in our new NFC-based access control product. We use NFC-A and T4 communication for Mifare Classic, Desfire cards, and Android NFC apps. The STSW-ST25RFAL002 with the following configuration seems to be using around 8KB o...
I am porting the ST25R3911B NFC module library to work with the Quectel EC200U 4G module in the Helios SDK. While I have successfully achieved rfalNfcInitialize and rfalFieldOnAndStartGT, I am facing issues when running the NFC-A polling code. The e...
I want to trigger a RFID reading at certain intervals using ST25R3911 and from this I want a RFID reading to be done within 1 second. When I try this in RFAL (using democode for polling): err = rfalNfcDiscover( &discParam ); if( err != RFAL_ERR_NONE ...
I have PCB which support 3.3 V or 4 V power supply which I want to connect with ST25R3911B. I want to run 4V power supply as it can provide more current and I assume outputpower of ST25R3911B will be higher on 4 V than on 3.3 V.In data sheet of ST25...
We checked the P2P communication and was successful in communicating between ST25R3918 and ST25R3916B.Is it possible to measure the P2P RSSI in the same way using rfalGetTransceiveRSSI()?In the case of NFC tags, we can get the RSSI based on the call ...
In my design VDD = 2.9V and VDD_IO = 2.0V. To minimize current when the NFC feature is not needed, I want to power down the VDD supply. But I want to leave VDD_IO powered on. Is there a concern with VDD being powered up and down repeatedly while V...
I've been reading through the Wake-Up Mode and Automatic Antenna Tuning application notes, and while I understand that AAT and Wake-Up with inductive sensing require more involved software wake-up logic, it doesn't seem to me that capacitive sensing ...
hi,st25r200 read configuration of st25tv02k tag via rfalST25xVPollerReadConfiguration() ,but always fail. Error code is 05.However, st25r200 can read and write user data block of the tag correctly.Could anyone give me an example of using this fun...
Hello,I am currently working as a student on designing my own hardware for reading and writing NFC tags. Although I lack experience in RF design, I have completed the electronic design and antenna matching process. My setup includes an STM32U575RGTx ...
