Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
I'm trying to figure out some unexpected behavior (that I've posted about before) after successfully implementing alternation between T2T Card Emulation and Reader/Writer such that they seem simultaneous to the end user.During device initialization, ...
Hi ， we had a problem with ST25R95 NFC solution， it looks OK to detect Mifare4 card at 10mm range， but have not any response to Mifare7 and Felica card.this is due to NFC antenna match？
Posted on April 21, 2014 at 05:45 Hi Everyone, I'm using the CR95HF to access the DESFire card. Everything was going fine up to RATS and PPS. However when I tried to send the GetVersion Desfire command (0x60) using the Half-duplex block transmission...
I am developing an Android app to read values from the NFC-v tag (ST25DV64KC). To revalidate my implementation, I am using the ST25 TAP app and then sending a custom command to test the commands according to the data sheet (ST25DV64KC). From an Andro...
Hey , I have tried a few strategies to fix my codebase. Ive now reused the same NFCTap App iOS project and customized it according to my view. Good news is that the previous problems are gone now. But sadly I am stuck in another problem now. Wh...
Hi there. I came across ST54J, which is an impressive NFC SoC capable of carrying out contact-less payment applications on its own. Unfortunately, only the databrief could be found on the product page. Where can I find the complete datasheet along wi...
Hello I am trying to use the NFC Tuning Circuit to use this anteanna (https://www.te.com/en/product-L000641-01.html) to work with ST25R200 (https://www.st.com/en/nfc/st25r200.html).Some of the parameters needed on the tool are not on the antenna data...
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 ...
