Resolved! MCU control the antenna function of ST25R3916
Is there a way to have any MCU control the antenna function of the ST25R3916, if we use the ST25R3917, as there is a stock shortage of the 3916 ?

Hi, I am working with the ST25RU3993 HPEV board. I have configured the API with the USA frequency profile and every time I launch a new inventory it runs the pre-tuning algorithm which takes about 17 seconds. Is there any way to avoid this? I mean, s...
Hi all,On a M24SR series NFC tag, after writing a NDEF message I need to activate GPO pin to wake up the MCU. On Android with java, this method exists: activePinGPO(NFCTag tag, OnNFCListener listener);And I'm trying to find the same method for iOS. J...
Hi,After executing rfalNfcInitialize() the consumption of my ST25R3916 it's about 6mA. How could I do to power down the device to achieve 0mA? I've tried with these functions with no success:rfalSetAnalogConfig(RFAL_ANALOG_CONFIG_CHIP_DEINIT);rfalDei...
Hi Could any one please tell me the difference between ST24DV04K & ST25DV04KC chips?In datasheet for KC , it says that it is Version-C in part ordering infoBoth ICs seem to work from 1.8 V to 5.5VWhat am I missing here?Kind regards
Hi,I would like to report 2 possible bugs on the rfalST25xVPollerWriteMessage implementation:The msgLen parameter must be "number of Data bytes minus 1", as a direct translation from the "Write message" command, but msgLen == 0 is not accepted as val...
Hello everyone,I would really like to use the X-NUCLEO-NFC06A1 expansion board in order to transmit power wireless. I read that it should be able to transmit 1.6W of power. At the moment I used the NFC06A1 available library to power up the board. In ...
Hello all, my company has decided to use the STM32L03 series for a simple ISO 14443-3 tag reader, and we underestimated how much memory the full rfal takes up. Can anyone help me find an easier way to cut down the provided polling demo into 16k fla...
I need to use STMCube IDE to work with STEVAL-SMARTAG1. Is there any sample project available ?I might not be required to access any sensors, so if there is any altered code available which only support NFC feature, would be better.#STEVAL-SMARTAG1
The datasheet (https://www.st.com/resource/en/datasheet/st25dv16k.pdf) states that "The impedance on LDP pin when set high doesn't exceed 5kΩ.", which means that a lot of power is wasted just signalling the IC to power down. Am I interpreting this wr...
