HelloI have a custom board with the st25r3920B. I want to operate this board in CE mode.So I set RFAL_FEATURE_LISTEN_MODE to true. But there is a difficulty because there is no sequence or example code for how to operate in CE mode.Where should NDEF ...
When calling (from C#):ST25R391xNativeMethods.iso15693Initialise(Handle, 0, false)I am getting an error response that decodes to "No Memory". I have had this error before when supplying a buffer that was too small for the response, however, no data i...
Hello,Is it possible to detect a phone using NFC/RFID readers?I am working on a wireless charger unit and trying to detect credit cards. When I put a mobile phone with a credit card, I am not able to detect credit card because phone is getting starte...
Good Afternoon,I am currently trying to read a text file from an NFC tag from an ST25R3916-AQET NFC reader connected to an STM32 microcontroller.I have tried to make use of the example case offered by X-NUCLEO-NFC08A1 but it only shows how to detect ...
Ask your questionWhy is the payload size not correctly written on my NDEF file?Environment :Target: STM32WB55rgTarget OS: baremetalHost OS: WindowsToolchain: STM32cubeIDELogs and console output if applicableI use it in my project NFC tag, which I rea...
I am trying to communicate with an ST25R95 from an ESP32S3 but the the spec isn't very clear on the SPI initialization sequence.and I can't find any complete examples. I'd like to verify that I can communicate with the ST25R95 by reading the IDN so ...
I am examining the antenna attached to X-NUCLEO-NFC08A1 and its schematics, and I noticed that there is a 3rd pad at the edge of the antenna board with a connection to GND. I also see the same GND connection through a 0Ω resistor in the provided sche...
Hello everyone, I am using the NFC TAP app on my iPhone to write and read ST25DV16. I am using X-cube-NFC4 to control the MCU and NFC. I meet two questions when I write content into EEPROM.Q1: I control the GPO interrupt when RFWRITE occurs, but when...
I have ported the driver of st25r3911 to nrf52832. At present, it seems that the initialization is normal. The value of the register read after initialization is the same as the value I used using the stm32 development board, but I just can't detect ...
Is there any example code for ISO14443A passive target mode, which is supported on the ST25R3916B? I'm prototyping basic functionality before fully implementing our application, and it would be nice to do a proof of concept without having to grapple ...
