Would like to use the ST25PC GUI to test a tag (ST25DV04K) ( in ST25FTM mode specifically)As i have difficulties finding a ST25R3916, I would like to know if I could use a X-NUCLEO-NFC06A1 on P-NUCLEO WB55 development board to communicate with ST25PC...
Hello,I'd like to get access to P2RAM to generate some sort of "Unique ID" between multiple ST25R3916 communicating with a single stm32 host Mcu.How to get Access & Read this memory ? i saw it was mentioned in the Datasheet but not elsewhere. Thank y...
Hi sirs,I have a ST25R3911B-Disco (NFC board) on hand, and my platform is STM32F767IGT6.My question is how to integrate the X-CUBE-NFC5 code to my existed project (Keil uVision5), I simply copy the major .c and .h files from RFAL and BSP folder to th...
Hi,I have M24LR16E-R product. I am reading UID and I see the IC ref product version 4Ch I was reading the IC ref value as 4Eh in the old versions I have. Looking at the ST documentation, I noticed that the value should be 4Eh. So is there any differe...
Can you explain why there are Near Field Communication antennas on both sides of this device? I'm designing Circuit for M24LR04E-R6MNT/2 I would like to follow the circuit diagram of X-NUCLEO-NFC02A1. But there are both side antennas. It would be ver...
Setup in use:P-NUCLEO-STM32WB development board.X-NUCLEO-NFC04A1 expansion board with software pack ( NFC 4.2.05) Added : DMA support for I2C , .ioc cubeMX image attached.The issue is that I cannot read the ST25DV ID via I2C DMA read. I simply do not...
Hello Can NFC tag be used to transmit audioif yes , which type can be used from ST and what reader would be appropriate.not the physical proximity tags but other thanks
Hello, sorry for the inconvenience but I really can't understand why I can't write/read new cards (the ones he has work) from my customer reader. What am I doing wrong?I enclose the photos, his card (working and writable / readable) and the one I cre...
We have used your ST25 NFC Tap app to read NFC tags emitted by a device with an ST25 chip. That has worked quite well up to a point when certain smartphones got their Android 12 update. Now the app displays an error.The phones are a minority but they...
In the app note an4974, ST recommends a matching impedance of around 16-20 Ohms, this part is reasonable and makes complete sense. In my configuration, I'm using differential with AAT. According to the app note, the target impedance should be at the...
