Hi all,I working with 2 EVB for ST25R3911b: ST25R3911B-DISCOthe ST25R3911B-Disco Board have a 2 loop ~950nH (105 mm x 52 mm) antennaI tried to replace the antenna for a custom antenna ( 80x48.5mm ~940nH ) very similar to the ST25R3911B-Disco Board.Th...
Hi everyone, I developed a NFC antenna with ST25R95-VMD5T device. This antenna is connected to my main board with multipole cables and comunicate via SPI with it.I tested it in laboratory and when I tried conducted emmission, appears this:(neglect th...
Hello,In our project we are trying to interfacing PN7150 NFC reader with STM32L4 controller to read and write to Mailbox of ST25DV04KC dynamic tag.We would like to know the command format, which i should use to discover the ST25DV tag, and write and...
Is FTM only available to use with development kits ? I cannot use FTM with mobile application. Is there any guide ?
Hello, I'm working on a bare metal implementation, reading ISO 14443A UUID and about 8 of the custom bytes. It's working fine. My question is how often should rfalNfcWorker() be called? Should this be called once per 100mSec, once per 1mSec, or jus...
Hi all,I'm currently developing an application with an X-UNCLEO-NFC03A1 evaluation board on an STM32L4, in order to write and read some NDEF messages on some ST25A02/16K that i have, protecting them with the 128 bits password.For starter, I'm running...
hello,I am working with ST25RU3993-HPEV baord. Getting all the list of inventoried tags in GUI (ST25RU3993 Reader Suite). I have gone through the ST25RU3993 SDK and tried to change the code to print the list of tags in uart. But iam unable to do so. ...
Hello, I ported the porting example to a different processor. The self tests are enabled and initialization passes. However I'm not able to read a tag. Logic captures (Salae) are attached. I've verified that I'm receiving interrupts and processing ...
Hi,I have downloaded en.x-cube-nfc5 project from:st(site)/en/ecosystems/x-nucleo-nfc05a1_htmlI have connected the X-NUCLEO-NFC05A1 Shield to one of my lab boards, based on STM32F103.I managed to make the whole thing work with this example: ndef_examp...
Hello Does anyone know what the impedance of the existing antenna matching circuit on the X-NUCLEO-NFC06A1 board is? I can't seem to find that information in any of the datasheets. I need the impedance so that I can design a new custom antenna. Br. J...
