Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Hello, I have a ST25R3916B project that is working fine, largely based around the demo_polling.c application. We use one '3916B and switch between different antennas. Each time we switch obviously the RF characteristics change a little, so I'd like...
Hi ST,One of my clients has asked me to design a PCB which will require the ST25R3916 NFC reader IC, and the ST25DV64KC, to share the same antenna, in order to prevent the tag from interfering with the reader.I have thought about using an RF switch, ...
Dear ST Community,I hope you are doing great.I am having a trouble to run the GUI of ST25R3916 discovery board on my machine, I have windows 10 operating system, I tried to reinstall the included drivers (with the GUI), but the GUI is not able to re...
Hi,I want to build a library for rfal and ndef from https://www.st.com/en/nfc/st25r3916b.html and use it with nRF connect SDK https://www.nordicsemi.com/Products/Development-software/nRF-Connect-SDKWhat is the proper way to build a static library? Th...
We are testing the app on a newer mobile and encountered this issue:Calling this function will cause the application to crash:mFtmCommands = new FtmCommands(mST25DVTag);The problem is in this procedure:private void setMaxTransmissionSize() { if (t...
Hi, I have a suctom board with st25dv schip and i want to use EH for powering it. By default, EH_MODE is ON_DEMAND and I want to change it to ST25DV_EH_ACTIVE_AFTER_BOOT like as at on the devkit, but after writing using SMARTAG1_NFCTAG_WriteEHMode(SM...
Hello:I am using the ST25 Dynamic NFC for energy harvesting applications in its batterless mode. I think there is a power management unit in the circuit but without energy storage such as a capacitor, is that right? If so, I need to add an external c...
Hello,We are using ST25R3920B as NFC reader for our project. In order to implement the functionality we integrated the nfc RFAL driver provided from ST. We need to develop the software with respect to ASPICE guidelines. I would like to ask whether th...
Hi Supporters: I used the St25r3911b IC to design NFC Module. Then, the new module could work. However, the waves at the Antenna side are not well, please check the picture at the end. I think maybe the matching circuit parameters do not ma...
After the last update the app is not crashing anymore, But how can I write data to it via the App. All toggles are not clickable. And the code example of the MX_NFC7_Process this function is completely empty. I realized to read the status by copyi...
