With the ST25R3916, how can filtering of the 3rd harmonic (40.5 MHz) be improved? Following the procedure outlined in AN5276, a matching network was made. Performance of the device was verified, and emissions in the 13.56 MHz band are within FCC limi...
Hi all,My aim is to develop an iPhone app with UIKit inXcode using CoreNFC to communicate to a ISO/IEC 15693tag. In particular, to communicate to a ST25DV64K type 5 tag.The data exchange between iPhone and tag is done by usingST25DV64K its fast trans...
I'm using XCube for develope. Can I use NFC6 for this board?
Hello Support team,@Travis Palmer We are working on the ST25R3916 NFC-based product.We are facing the issue of high power consumption during NFC active scanning operation so, we want to start the NFC active scanning mode on the External field detecto...
Hi, I want to use the Fast transfer mode on ST25DV64KC. I am using X-NUCLEO-NFC03A1 as a reader. When I write code for fast transform mode in X-NUCLEO-NFC03A1, I get an error. Do I need to make any adjustments in ST25DV64KC? Rgds KU
I am trying to update the firmware in the STEVAL-SMARTAG2 using Memory & File editing in STM32 CubeProgrammer Windows Application., but I get Error: failed to erase Memory.My goal is to install your demo firmware to use the SMARTAG2 with ST NFC Sens...
I've got a STEVAL-SMARTAG1, and i need to build a React Native App that reads the sensor reading stored in the memory via RF.To do so i'm using "react-native-nfc-manager" library to use the NFC sensor on the phone to read TagData but that doesn't con...
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...
