Dear Community,i'm looking for a solution for NFC antenna of range ~10mm and M24SRxx-Y. The space on double layer PCB (1.6mm) is limited to max. +/- 20mm x 8mm, tag should be read by a mobile app.Does anyone experienced / has a reference design for s...
After reading the data through the ios NFC Tap app, the Linux platform can't read or write data to the ST25DV64KC through the iic.Below is a log of the app after it was read and operated with linuxBelow is the log that is not read with the app and op...
Dear..STI'm developing custom NFC PCB 4 layers 0.8mm based on 20x20mm main antenna example in STEVAL-25R200SA kit.I tried to use the components in BOM for EMC filter L 0402DF-421XJRW 420nH 510mOhm and adjust frequency to18MHz and get EMC capacitor 1...
My organization is currently planning to develop a monitoring unit that will connect with a mobile app via NFC. For this, we have chosen the ST25R3916 NFC module, with the STM32WLE5 series controller as our main MCU. Recently, we started working on t...
HiI Reported this for Improvement in STSW-ST25RFAL 3.0 source before.Now STSW-ST25RFAL 4.0 is available but the following problems are not changed.1) Add to rfal_analogConfig.h, rfal_crc.h, rfal_iso15693_2.h header files.#if defined( __cplusplus )ext...
I'm developing an app that writes and reads settings from an STM32 over NFC. I can write settings to the ST25DV mailbox and poll the RF_PUT_MSG register to detect when data has been written. Which register should I poll to know if the app has request...
I have designed RFID and I am now trying to deternine the antenna parameters by followingAN4974 Antenna matching for ST25R3911B/ST25R391x devices I have bought NanoVNA-H4 for doing the measurements.But what confuses me is how to connect the RFID ante...
I drew a pcb with antenna and put st25dv on itbut i get read data error on the st appis that st25dv need to program first?or just my soldering is bad? or antenna isnt standard?the antenna is designed as this P.S. I can read the tag by other app call ...
HiI download the newest STSW-ST25RFAL 4.0.0 and try to update my project from STSW-ST25RFAL 3.0.0. In rfal_nfc.c is a new function platformTimerGetRemaining( ) used.I can't find a sample implementation because STSW-ST25R_1.7.0 is still with 3.0.0.Whe...
Hi everyone,I am working with the STEVAL-25R200SA evaluation board using the ST25R200 GUI software, and everything is functioning correctly.However, I would like to develop my own software instead.Using X-CUBE-NFC10 Middleware:Can I use the X-CUBE-N...
