I am trying to get the demostration firmware to output some logs through UART or USART but was not able to do so.Both USB cables are connected (micro and mini) and I used Putty to connect to the Mini USB interface (ST link USB port). I also put the b...
Hi there,I made a design with the CR95HF and it's working. The design of the EMI filter and matching circuit is done like on the X-NUCLEO-NFC03A1 NFC card reader board, see [UM1799] page 12.I'd now like to tune the components on my design to increas...
Hi,Am working on making a RFID reader using the ST25-EVAL kit. According to its user manual, it is capable of transmitting at 29dBm with external PA. I intend to use this with a 8dBi far field antenna. What is the typical distance my reader can detec...
Hello,I'm using the st25dv04k NFC tag and accessing to the memory with the ST25 App.I have 3 memory areas: the first 2 (Area1 and area2) of 32 bytes and the third area the rest.The problem comes when I'm trying to add a NDEF URl record to open a link...
Hello,I had DIN CR95HF in my project, but I measured Zout differenceital impedance is around 60Ω via VNA equipment.per my checked data sheet, the ZOUT differential impedance between TX1 and TX2(1) 27 Ω I used Murata bead blm21bd601sn1b EMI filter in ...
Hi all,I am current tinkering with the NFC03+NUCLEO board and the NFC DISCOVERY board for some custom NFC applications.A couple of questions.I understand that the NFC03 (at least the board I'm having) implements a CR95HF and has examples of reader/wr...
Hi, We are testing the ST25R3916 to read Mifare 1K classic UID's.We manage to initialize the chip and to send an REQA command (We get 00 04 back from the card so communication works!).But we need to know the UID. To do this I found the APDU command:C...
Where to I start to debug the RFAL middleware if I receive ERR_PROTO (11) when I call err= rfalIsoDepStartApduTransceive(P); or rfalIsoDepGetApduTransceiveStatus();I receive ERR_PROTO from the RFAL when I send a card a specific (APDU) , For some card...
Does ST25DV64K support the extendedReadMultipleBlocks command sent by iOS 13?Although the data sheet says it supports but when I try that command using iOS 13, I keep getting the error: Tag Response Error.And when I set the start block number larger ...
Hello,We are planing to use ST25R95 in a new product. It's now in a component selection stage, but we have some eval boards and test code already done, so we would like to use this IC.We need enough security to authenticate tags and prevent tag copyi...
