I want to read an M24lr64E NFC tag from the X-NUCLEO-NFC03A1 board. this is really compatible with the Arduino UNO but I can't find an example code for the Arduino UNO. If anyone have a arduino code for X-NUCLEO-NFC03A1 board, please share with me.X-...
Hi there,We are working with the ST245RU3993 and have the EVAL board working correctly with the provided GUI.We now want to control the ST25RU3993 via SPI with a ARM MCU. This ARM MCU will operate independently, as sketched in "Device side usage" in ...
Hello,is it possible to switch from LISTENER to POLL mode at runtime and vice versa? I have enabled both POLL and LISTENER at compile time but only the reader mode works.Any suggestions? can i do it via register?Thanks and regards
Hello, We have an pluggable antenna connected to a ST25R3911B. We need to find an efficient way to detect when the antenna is plugged/unplugged. What is the best way to do that?
I downloaded your last ST25R39xx library examples (about Bluetooth, RW ...); I can write NFC URI tag in Card Emulation mode (without some NDEF_NOT_DETECTED messages during the transfer), but not NFC WiFi message . So I succeed to write tag in CE mo...
Hi,We have an ST25DV04K NFC tag which is being used to communicate to a host microcontroller from a mobile app and we're having trouble with FTM after booting up the host device from the app.We're starting up the host from this app by pulsing the GPO...
We are using ST25RU3993 IC with STM32L476 MCU. We are using the same SDK Provided by ST. But after giving the command of Start Scan in GUI(ST25RU3993 Reader Suit), we are not able to read tags. We also checked the signal on PAOUT_P and PAOUT_N throug...
Hi, Can we use ST25RU3993 Eval kit in Device mode directly(instead of Host driven), without using the GUI application.Need to use it directly without using GUI Application for making configuration for detecting the TAGs. Please let me know if such se...
