About reading tags via USB UART by ST25RU3993 without ST25RU3993 Reader Suite GUI.To initial and start reading tags automatically after plugged in and print them on serial terminal (ex: Tera Term) via USB UART (not the UART LOG pin) by ST25RU3993 wit...
Hello everyone, I want to design with st25dv only RFID systems. I cannot find any example about this. Do you have any suggestion?
Hi ,I integrated st25dv64kc nfc tag into stm32 board. I have to store a serial number permanently in NFC EEPROM user area. It should not be erased in RF write and I2c Write. I used NDEF format . Is it possible to store text permanently ?
Hello we have integrated ST NFC RFAL stack with RL78 IC and currently we are able to detect NFC card within 1-2seconds. Is there a way to reduce this time less than 1 second to detect NFC card ?
We are designing a board that uses the ST25RU3993 Reader. We will have a Raspberry Pi 2040 microcontroller on the board for communication. Do you have any firmware or code that can be used to communicate to the reader from this Microcontroller?
We are writing an Android program to read an ST25TV02KC tag (an ISO 15693 tag), and we cannot use the ST or NXP library. Instead, we need to send protocol commands directly, but the datasheet specifies that CRC check should use CRC_B. As far as we kn...
Hello there, STM32 community!I am new to the STM32 family and I am currently working on a project to read and write Mifare Classic and Desfire tags. For this, I am using an STM32G071-NUCLEO64 microcontroller and a X-NUCLEO-NFC05A1 (ST25R3911B) board ...
I have programmed the temperature sensor, but it seems that it has not been successful, the NDEF reading result is shown in the figure, what should I do?if( NfcType5_NDEFDetection( ) != NDEF_OK ) { CCFileStruct.MagicNumber = NFCT5_MAGICNUMBER_E1_CCF...
We are using the CR95HF over SPI and communicating with a single NTAG213 tag.I can successfully configure the reader and read 4 pages of user memory reliably using the READ command: 00 04 03 30 04 28. // Reads 16 bytes from Addr 0x04We would like to ...
Hello, currently testing the new ST25DV64KC tags to replace the old M24 in our product lines....All the test phones managed to read/write via NFC, using your ST25 app.......Except the motorolas. G30 and G50 never go past the the "please tap an nfc ta...
