Hi, I bought ST25RU3993-HPEV and In the tag authentication menu I want to use 29167-10 as CSI and there is a field with 'keyID' parameter. I want to know what is the key which this ID is assigned to. you know, the key in the tag and the the reader mu...
I have been asked to implement functionality for a Feig NFC-reader ( ID CPR30-USB) into an existing C# desktop-application.However, I only find some SDK-like thing for Java (the "ST25PC-NFC"). But I would need something for C, or C++, or C# or Visual...
Hi,I am using a ST25R3920 to emulate a type 2 tag. I have got the Read part working and I am able to send 16 bytes of data in response to 0x30 and confirm the data on a phone. But when the phone tries to write data using 0xA2, I am unable to send the...
Hi Sirs, I want to buy an NFC WLC evaluation kit similar to the one shown in the picture I posted. Where can I buy?
Hi all, I’m using an ST25R3916 with RFAL on an STM32 and I’m trying to talk to an NXP NTAG 5 Boost (ISO15693/NFC-V) using its custom commands: READ/WRITE SRAM (0xD2/0xD3) and READ/WRITE I²C (0xD5/0xD4). Plain ISO15693 commands work fine (e.g., Read...
I am using a NUCLEO-L053R8 board with an X-NUCLEO-NFC08A1 extension. I made modifications to the NFC08A1 to enable I2C communications and this works. I can read the A bank of registers and the values all make sense except for IO configuration registe...
Hi,We have duplicated the design onto our own NFC tag, copying the same antenna design onto a flexi pcbWhat should be the tuning capacitor for this coil be for NFC ?If thats not available, what is the inductance value of the antenna so we can try and...
Hello,I am using the ST-25R200 ready-to-use NFC evaluation board for my application. I have already used the ST25R200 EVAL GUI software which functions without any problem. Since I want to develop my own software and integrate it for the application ...
