Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Hi everyone,I am currently working on a project involving the ST25DV NFC tag connected to a microcontroller (STM32). My goal is to test the Fast Transfer Mode (FTM) functionality. Here's the workflow I am aiming to achieve:1. An NFC device (e.g., a ...
Hi, Just to confirm, if AAT is not used , AAT pins must be left open? thanks in advanced
Hey,I want to test an off the shelf Molex NFC antenna 15*15 mm using the ST25R3911B. Is it possible to connect the antenna to the discovery board as I wanna evaluate the antenna whilst connected to the ST25R3911B? If so, how can I test the setup? If ...
I am using st25r3911b with an esp32, it works fine when i use the disco board (the original stm microcontroller desoldered). But then I decided to make my own circuit as shown in the attached image. The rfalNfcInitialize() function returns errors 0, ...
I'm trying to establish communication - FTM between ST25R3911B and ST25DV64KC . I'm running the example program in the reader module and I have enabled the mailbox in the dynamic tag side. The reader is able to detect the dynamic tag and is trying t...
Hello, I'm having trouble reading single blocks in the M24LR64E-R tag I'm developing the app in Flutter and I'm trying to send the command in the following structure final command = [ flags, // flags 0x20, // Command: "Read Single Block" ...uid,...
I've been seeing some unexpected failure modes while reading T2Ts with an ST25R3916. Every ~300ms, the device sends a wake request, and if a tag is detected, goes ahead with the reading process. If a tag is detected and an error occurs anywhere in th...
Hello, I am trying to get the ST25PC app to connect to a FEIG-CPR30-LCN9620 which I believe should be supported; however I not able to get the correct drivers to do so(Which I believe is the problem); I downloaded the most recent drivers from Feig we...
Hello, I am trying to enable the Mailbox functionality on ST25DV64KC-DISCO board. I am using the NFCTap project,And inside it added my own storyboard and a View controller.This view controller first detects a tag at launch in view didload,then it fet...
Hello,I have a question need your help!About :MCU L431(80MHz),SPI 5M,IC ST25R3916. NFC06A1I use "rfalNfcvPollerReadMultipleBlocks()" read two blocks at a time,but I found that it takes 9 ms to read successfully. How can I shorten this time?
