Is there a simple example code to read a Tag NFC with st25R3911?

[MChiu.2]

Hi all, I'm trying to write a simple code to read a Tag NFC type 2. I have a EVK NUCLEO stm32F446 and X-nucleo-NFC06A1, I want connet they with I2C. and write a simple code to wake up st25 when I send a high signal and read eeprom of tag and show this information via UART.

Hi,

X-CUBE-NFC5 (ST25R3911B) package and X-CUBE-NFC6 (ST25R3916) package provide code and example for tag detection, NDEF read/write/etc. The demos display information on a serial console. For T2T, rfal_t2t.c provides the API for reading/writing blocks.

Just a note about X-CUBE-NFC6 (ST25R3916) actual version is v1.0.0 (and is quite old) which use a an old RFAL V2.0.10 / 25-Jun-2019

Could you check to update it to use latest RFAL V2.2.0 / 22-May-2020 which is available here

Hi,

 X-CUBE-NFC6 (ST25R3916) v1.0.0  already includes the various demos and the support for T2T read/write. So it can be used as is for your prototyping. For a final product, it is recommended to update to the latest RFAL. RFAL deliveries are more frequent than  X-CUBE-NFC6 deliveries. I will check for the next update

Hi guys,

I'm new to this. I'm using Nucleo L476RG in combination with NFC 4 Click. I downloaded the X-CUBE-NFC6 but when i go to read an NFC Tag nothing happens. NFC 4 Click device has ben succesfully initialized What am I doing wrong?

[Brian TIDAL]

Hi,

I would suggest that you create a dedicated post for your issue as you have a different HW environment (NFC 4 Click which is different from ST X-NUCLEO-NFC06).

Thanks
