I need the mobile phone to use NFC Tap to read the dynamic data information of the sensor in the STM35L476 microcontroller. What should I do? Is there any relevant programming reference?

Is there any code about APP reading the sensor signal that STM32L476RG transmits to ST25 through I2C? Is the data transmission read through mailbox of mobile app?

[Rene Lenerve · Accepted solution]

Hello,

If you want to transfer data through the mailbox feature, it means that you are using an ST25DVxxK or ST25DVxxKC component.

So, you can found on st.com simple source code examples with our NFC4 (ST25DVxxK) or NFC7 (ST25DVxxKC) expansion boards with corresponding firmware X-CUBE-NFC4 or X-CUBE-NFC7. That will allow you to read/write mailbox or EEPROM.

You can also found demo package source code that works with our ST25DV Discovery Demo Boards here : Discovery demo firmware. It will show you how to exchange data with ST25 NFC App and the Tag using an STM32L476.

I hope this can help you.

Kind Regards.
