Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
I use ST25R95 to detect the ST25D tag. I keep the tag on the antenna of the Reader all the time, and some situations have occurred. Hi Even if I place it precisely on it all the time, the tag may not be read probabilistically during detection. Is thi...
Where can I find details on inductive sensor wakeup for the ST25R3916? It's only even mentioned on pages 1 and 11 of the datasheet. My understanding is that inductive wake-up will detect tags only, whereas capacitive will detect other objects like a ...
Hello,I would like to know where I could find the ST25FTM library for Android.Thank you in advance,Best Regards,Selvaraj
Hello, everyone,I have a problem with setting the GPO of M24SR64-Y as an INTERRUPT. The micro needs to come out of Sleep condition through an Interrupt sent from smartphone via RF, I saw that you have to set the GPO with 0x4X, but I don't know how to...
Hi,Can anybody tell me whether the X-NUCLEO-NFC07A1 works with an Arduno Uno ?In other words, can I just plug an Arduno Uno onto this unit, or do I need to buy a STM32 development board ?When plugging it onto a normal Arduno Uno I am unable to read a...
Hello ST Community!I am using the M24SR64-Y NFC front-end in my system where the microcontroller is always in a SLEEP state and it is woken up by a SendInterrupt from the Smartphone.The microcontroller is used to perform weight measurements.I would l...
I'm adding Power-Down mode to my Listen Mode implementation, and have come across some unexpected behavior.I keep the chip in Power-Down, with the field detector set to automatic, and then see EON when a field is detected, as expected. The first time...
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...
