Hi everyone,I’m currently working with the ST25R3916B NFC reader and controlling up to 6 external antennas via a multiplexer. The antennas are activated sequentially, i.e., I switch between them one after another in a polling loop.However, I’m experi...
Hi,I’m currently working with the ST25PcDemoApp. The project works well on its own—it can detect ST readers, read tags, and write NDEF messages successfully.Now, I’m trying to add FEIG reader (MR102) support. To do this, I copied the FEIG resource fi...
Hello,I am using the ST25R3920B NFC reader in wake-up. My goal was the interrupt pin only came to 1 when it detected the presence of a smartphone (or other strong RF fields), however currently the interrupt pin comes to 1 periodically without any RF ...
Hi!I am currently using the X-NUCLEO-NFC08A1 and NUCLEO-F411RE boards to develop NFC-V related applications. I am encountering an issue when trying to set the power level of the NFC08A1.I use the following function to adjust the power level:void set_...

Hello, I am writing a mobile application to interact with a STS25DV04KC-I chip. I am encountering problems when trying to write to to user memory on this chip from iOS using the ST25 framework.I want to write a byte array into area 2, and to modify t...
Is it possible to use RFAL with ST25R200/R100 without utilizing the additional IRQ / EXTI Line? So just the SPI connection?
Hi everyone,I'm currently working with the ST25R3916B and trying to detect two NFC (ISO15693) tags simultaneously in the RF field.I'm using two ST25TV02KC tags and placing them close together above the antenna.However, my current implementation only...
