I use the ST25DV04KC. I initialize the chip and write to like the eval software the CCFile to Block 0 this works. In this state the chip is CCFile unlocked, the NFC-Tag protocol is selected to Type5, RFMngt_Dyn is in NFC off mode (0x01) and I2C secur...
Hello togetherI am working on NDEF and mailbox communication between an Android smartphone and an X-Nucleo-NFC04A1 Eval Board. The Eval Board X-Nucleo-NFC04A1 communicates with a MB1717 STM32C031 board.The embedded part works perfectly, the implement...
HelloLast week I received the ST25RU3993-HPEV devlopment kit. I have already downloaded the SDK and tried it out. Unfortunately, I have not found any information on how to write firmware for the board myself. Is that even possible? Or is there a way ...
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...
哈喽！ST官方，本人使用ST25R3911B这款芯片做NFC识别方案；同样的电路，做了5块板子，发现天线识别NFC标签的表现不一致；1、1号板子可以正常识别NFC标签；2、2号板子不能正常识别标签，需要调节匹配电路参数，且这两款板子调节的参数不一致；3、将1号的板子调整为2号的参数，1号板子无法识别，工作不正常；4、其余的板子也是，调整参数都不一致，才能正常工作。请问，大佬们，这是什么原因？都是同样的电路。

Hey All, I'm looking to bootstrap a custom NFC antenna and was wondering if anyone could point me in the right direction for how to attach a ST NFC chip to a silver nanoparticle printed antenna using a laser jet (with this ink). Someone suggested us...
I'm encountering an issue with NFC functionality on iOS, specifically related to reading multiple areas. I have an NFC tag that stores data across three distinct memory areas. Using an Android device, I can effortlessly access all three areas with ju...
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...
Hello,I have made a custom RFID reader board design which is similar to the X-NUCLEO-NFC08A1. However, it powers antennas in single ended mode with a cable through a u.fl connection. I am running the example code for the X-NUCLEO-NFC08A1 on this cust...
