I would like to use ST25DV-I2C for I2C communication and GPO output.The datasheet states that to use GPO output, an external pull-up is required for the 8-pin package, and an external power supply (VDCG) is required for the 12-pin package.However, I ...
We are using an ST25R3916B to read and write to both ST25TV512C tags and Mifare Classic 1K cards. While we have successfully communicated with ST25 tags, we are encountering issues at the authentication stage with Mifare Classic.Steps We Are Followi...
Hi everyone,I'm working on a product that involves multiple sensors connected to a main system. Up to six sensors can be attached (see image). The overall diameter of the system (as shown in the image) is approximately 20cm. I want to use NFC tags on...
hello, im designing an RFID board, using the ST25R3918, no where in the datasheet have i been able to find what to do with BSS/MOSI (float, pull up or down). I saw that BSS is used with I2C regarding transparent mode, but that's not needed for my pro...
We are having an unusual issue where we are failing emissions at 67.8Mhz or the 5th harmonic of the NFC frequency. We are also close to the limit for the 3rd and 4th harmonic as well. It is unusual because it does not fail in all operating modes. ...
We checked the P2P communication and was successful in communicating between ST25R3918 and ST25R3916B.Is it possible to measure the P2P RSSI in the same way using rfalGetTransceiveRSSI()?In the case of NFC tags, we can get the RSSI based on the call ...
Hello!We are using ST25R3916B in our new NFC-based access control product. We use NFC-A and T4 communication for Mifare Classic, Desfire cards, and Android NFC apps. The STSW-ST25RFAL002 with the following configuration seems to be using around 8KB o...
I am porting the ST25R3911B NFC module library to work with the Quectel EC200U 4G module in the Helios SDK. While I have successfully achieved rfalNfcInitialize and rfalFieldOnAndStartGT, I am facing issues when running the NFC-A polling code. The e...
Hello,I am using the Nucleo-STM32F411RE development board and X-NUCLEO-NFC08A1 NFC module, particularly NFC Tag read/write from Android Phone for my development use cases.To achieve this, I downloaded the X-CUBE-NFC6 package as it was mentioned in th...
Hello!I am using ST25R3916 (X-NUCLEO-NFC06A1) and RFAL Library V3.0.1. When working with STM32L4RGT3 (NUCLEO-L476RG) everything works fine, but if I use STM32L053R8 (NUCLEO-L053R8) functions rfalNfcaPollerFullCollisionResolution() and rfalISO14443ATr...
