I was trying to setup the software (ST25R010) for NFC reader, and not only was I unable to setup the software but I realized the board malfunctioned at some point. The board initially worked fine but now it shows a reversed error message and I cannot...
For our NFC project, we are developing a mobile application that supports both iOS and Android. We are using React Native along with the react-native-nfc-manager library. Some of the core features include reading and writing raw memory blocks as well...
This is a custom-made PCB antenna board utilising the ST25R3911B chip, but I am unsure how to proceed with impedance matching debugging and parameter configuration. Could you offer some guidance? Below are the antenna dimensions, the calculated imped...
Hello @all, I've downloaded ST25DVCryptoDemo for iOS from here, in order to take a look into the demo code for a new project.Once I've tried to build the Demo app I've got a big amount of errors. In fact the console gave me this message "too many err...
Hello everyone. I'm currently developing and testing an embedded C software for microcontroller STM32L476 integrated on board ST25R3911B.In order to better understand FTM and its features, I'm trying to use a ST25NFC_Embedded_Lib_ST25R3911B_1.8.0 dem...
Hi all，I now use ST25R3920B as a card reader on the official nucleo nfc08A1 of ST to read cards. However, I found that when the card was detected by 3920B, the current increased to 300mA, but the maximum current borne by PCB was 350mA.Can I reduce th...
