Hi,I have implemented a NFC sniffer for Flipper Zero (with ST25R3916), and I found wrong information in the datasheet regarding the default values of the chip registers (all of them in Space A): Register 0x0c defaults to 0x2d rather than 0x2c as indi...
Hello every body.I hope you are doing well.We are designing a smart card reader can communicate with java cards both contact and contactless.Our MCU is STM32F405RGT6 and we want to use ST8024L for contact section.For contactless section we decided to...
Hi When transferring a Type-v signal at 26kbps and at 53kbps, what is the frequency bandwidth/spectrum of these 2 signals? This helps me to set the bandwidth of the baseband amplifier in the reader correctly. Thank you.
Hi,I'm not able to use the GUI (W7). The DFU driver is not detected and the guidelines to fix it are not clear.At page 5/32 the UM2517 claims:Enter “C:\Program Files (x86)\STMicroelectronics\ST25R3916_Discovery_GUI\Driver�? and install it.But the \Dr...
Hello everybody, We hope you are doing well.we planned to use ST25R95 chip to create a smart card reader that can communicate with all smart cards and java cards (MIFARE and NFC). we read in ST25R95 datasheet that this chip does not support write act...
Hi everyone,I have just discovered that I have multiple errors when I try to read more than 30 blocks, rfalNfcvPollerReadMultipleBlocks() function depending on the number of blocks I try to read.Firstly, I want you to talk about the TAG I am reading:...
Hi supporter, I'm working with ST25R for NFC reader which read e-passport.In our current set up, system run on STM32MP1, some open source provides example via CCID and pcsc-lite driver.Based on my knowledge, currently only userspace application is su...
Hello,I'm working on a project where I'm using the ST25R3918 with RFAL libraries. Initially, I read the IC identity register and performed a right shift. Why did I perform this right shift?I modified the read register function, added a right shift, a...
I am using ST25DV chip as NFC RF chip, can X-NUCLEO-NFC07A1 have an external antenna?Can ANT7-T-25DV64KC have an external antenna? Is there any other can external antenna?
Hello, am using RFID card reader ST25R95 using its stack. I want to reduce the fixed wake up time from 300ms to 100ms. #define RFAL_ST25R95_IDLE_DEFAULT_WUPERIOD 0x24U /*!< Fixed WU Period to reach ~300ms timeout with Max Sleep = 0 */Is there any met...
