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...
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...
Hi there!I'm working on a Windows console application which uses ST25R3911DISCOComm DLL to communicate with ST25R3911B-DISCO board to process a ISO 14443A card (ST25R3911DISCOComm DLL is located in ST25R3911B_Discovery_GUI App installation directory)...
Hi, We have a product with ST25R3911B and we failed the EMI pretest, mainly due to 3rd harmonic at 40.6MHz.I suspect that this is because we use polling for RFID tag detection, and the reason we are doing polling is because in wakeup mode the device ...
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。
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 ...
I always get the error:-[NFCTagReaderSession transceive:tagUpdate:error:]:888 Error Domain=NFCError Code=100 "Stack Error" UserInfo={NSLocalizedDescription=Stack Error, NSUnderlyingError=0x282891950 {Error Domain=nfcd Code=54 "Session não ativa" User...
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 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...
