Resolved! [solved] having trouble reading simple NDEF records from NFCA Passive T4T cards

ST25R3911B, using the ST25RFAL001 and the NDEF library v1.0.4. I'm using the read example found in the ndef.chm file. It's detecting the card fine, but ndefPollerNdefDetect() is returning 0x5 (invalid request or requested function can't be executed a...

Resolved! Cannot detect tags when using RFAL for st25r3916 on custom board. Need guidance on register config.

Hi. We are using the RFAL implementation for ST25R3916, with I2C communication. We have a custom board and antenna. We are using the Polling tag detect demo app to do passive NFC-A detection. I have disabled automatic antenna tuning and set the I2C p...

Resolved! Understanding AAT values?

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...

Resolved! X-NUCLEO-NFC03A1 Card emulation and sleep?

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 ...

Resolved! is there a difference between ST25R3911 and ST25R3911B?

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.

Resolved! ST25R3916 or 3917 with two antenna

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 ...
