I'm using the NFC06A1 and NFC-V tags with demo_polling.c and RFAL_ANALOG_CONFIG_CUSTOM in platform.h During the DEMO_ST_DISCOVERY loop and when the case is RFAL_NFC_LISTEN_TYPE_NFCV I am querying the values of the st25r3916AatTuneResult (from st25r3...
Hi,I have a custom board with ST25R95 chip, and I have successfully implemented the card emulation on the custom board without going to sleep(discParam.wakeupEnabled = false).It draws a lot of current, and I need it in sleep mode, but If I set it to ...
We are moving from ST25R3911 to the latest version ST25R3911B with the firmware and the other circuitry remains the same. But we are seeing the reduction in operating distance for the cards.
Hi,I was wondering if we can use the ST25R3916 or 3917 with two antenna. We connect one on the output/input of the RFO1/RFI1 and the other on the RF02/RFI2. Is that something possible ? I can't seem to find my answer in the datasheet.Also, I want to ...

I need an NFC module that reads data from NTAG216 cards and also supports Android and IOS phones that send NDEF message from the phone to the NFC module. STM has many variants and models for NFC . I am totally confused and dont know where to start. C...
I'm trying to decide between the ST25R3911B or the ST25R3916? I realize the ST25R3916 is newer; but newer does not always equal better. Are there any advantages to developing with the ST25R3911B? Primary purpose is to read 15683 transponders in a ...
The RF password can only be set over RF, I2C has no ability to access these registers (RF_PWD_0/1/2/3). If an RF user sets a password, and then forgets it, is there any built in mechanism to reset the password back to its factory default, or some ot...
I want to use ST25DV-I2C's Fast Transfer mode on iOS and Android.It seems that it can be done on Android, but is it possible on iOS?I would like sample code if possible.
Hello. I use board st25ru3993-eval and application ST25RU3993 Reader Suite. When tags are readed we can see RSSI LOG Channel I & Q and Input Power. RSSI LOG Channel I & Q we can find in RSSI Display Register in AS3993, but i do not understand how cal...
