Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
Hello everyone!I’m developing a device that will include an NFC Tag, and I’ve chosen the ST25DV64KC. This Tag needs to be mounted on a case and communicate with the "mainboard" of my project via I²C. Therefore, I’m working on a small circuit that wil...
HiI`m going to develop a app to display image on ePaper by coreNFC ISO15693, but i have only 20sec to transmit data and display image when phone connect on epaper . I can use session.repolling() to extend life scycle of NFC session lower iphone13 or...
Hello,Is it possible to have the thermal resistance information on ST25R3916B-AQWT?Regards and ThanksMadhu
Hello, I have a question for NFC R/W mode (read/write EEPROM with ST25DV16K)tag : ST25DV16K - Nfc tag 4 clickreader : STM32 + X-Nucleo_Nfc08a11. When writing data to the ST25DV16K board via RF, how long does it take to read the data via I2C?2. It tak...
Hello everyone,I am using the X-NUCLEO-NFC08A1 NFC Shield that has the ST25R3920B chip. I want to know if it is possible to use this to make OOB Bluetooth with my android smartphone, and if so how can I achieve it. I read some documentation regarding...
Hello!Can you tell me the reasons and meaning of the necessity of grounding the center of the ST25R3916 antenna loop?In X-NUCLEO-NFC08A1 the jumper between the center of the antenna loop and ground is closed, but in ST25R3916 Discovery Board it is op...
Greetings,I've got a simple application wherein I'm exchanging ISO-DEP data using RFAL on a ST25R3916. I'm only interested in handling the data read from the card once (of course) and then only process read-data again from either a new card OR the s...
I've been implementing Wake Up mode with inductive wakeup on the ST25R3916 with custom firmware. It's all functioning as expected, except for the oscillator interrupt.As seen in the logs below, when I switch to Wake Up mode, I mask every IRQ except I...
To perform the demos, the ST25 Android app is asking me to upgrade the firmware by PC and telling it can't be done by the Android Application, but when I open the ST25PC-NFC software, it doesn't detect the reader and hence can't upgrade the firmware....
Hi, I am using an ST25R3911B using the ST25NFC_embedded_library in polling mode on an stm32f103CBT6. In my program, I poll my ST25 and then move on to reading values from arrays of hall sensors (4 arrays of 16 sensors each) a total of 64 sensors. The...
