Hey,I recently bought ST25-TAG-BAG-UI1 and hoped I could experiment with it for a specific application but I soon realized there is no documentation available publicly. I've applied for access to AN5580 but my application got rejected (I guess becaus...
I have integrated the ST25R3911B into a Linux development board, using spi+gpio for communication.I currently have GPIO configured for edge-triggering (both), and I am polling for card readings at a frequency of 300ms.However, I've noticed that the G...
Dear Sir We are developing an iOS mobile application software. We downloaded the official source code of ST and compiled the app we need.When verifying the development board, we encountered the following problems: the ST official app（STSW-ST25IO...
前段时间使用ST25R3911B成功实现透明模式的通信，很遗憾的是ST25R3911B不支持负载调制，从而选择ST25R3916B作为替代。目前已经将ST25R3911B透明模式的代码移植到ST25R3916B的芯片上，使用的是OOK的调制方式，移植之后发送数据的已调信号是正常的，接收的信号通过MISO引脚输出异常，如附件图片所示。MOSI引脚负责调制载波，理论上MISO输出的脉宽应该与基带信号一致，这点在ST25R3911B上可以验证。问题1：ST25R3916B在透明模式的接收配置方面，相比...
Hello, We are trying to implement the isodep functionality in one of our developments with the ST25R3917, acting as reader/PCD. We have implemented the libraries included in the STSW-ST25R018 firmware (https://www.st.com/en/embedded-software/stsw-st2...
Recently, I am working on a project. I need to use the nrf52832 driver st25r3911b chip to read the card. The current progress is that I can use the st25r3911 driver to initialize, and the initialization has been successful, but it seems that there is...
At the moment, I am using the default firmware on the ST25R3911B-DISCO and have been reading and writing to a ST25DV04K tag. I know that the ST25DV04K tag supports a size of a 256-byte buffer, but I am wondering if the ST25R3911B does as well. If it ...
Hello,I am using ST25R3916 based X-Nucleo-NFC06A1 with Raspberry-Pi to read data from ST24DC64KC tag (which is custom board) using FTM. I am able to read the message using rfalST25xVPollerReadMessage(), But only if length is below 128. If I am tryin...
I am working on ST25DVXXKC tags with ST25R3916 Reader based application.Issue: While using ST25R3916_v2.8.0_Linux_demo_v1.1 for raspberry pi, I encountered an issue -> "library compilation failed with undefined symbol".Cause : As I am using NFC-V tec...
Hi,I am assessing to use ST95HF chip or ST25R95 chip for Bluetooth pairing (use NFC Data Exchange Format) application and reader mode of NFC Tag URL.I would like to know if above two functions can work on the chip at the same time.And does the softwa...
