Flash using NFC

On one side I have a slave MCU and other side smart phone. I have an nfc tag connected to slave MCU via I2C. Is there any way I can flash the software from smart phone to the slave MCU using NFC? Given I have some 500 Bytes EEPROM on the NFC tag.

Hi,

ST25DV-I2C features an innovative fast transfer mode between an embedded host and an NFC phone or reader thanks to its half-duplex 256-byte buffer (mailbox). This enables use cases such as firmware update, file transfer. etc.

An end to end firmware upgrade demo from an Android phone to an ST25DV Discovery kit is available thanks to the "NFC Tap" Android app (available on GooglePlay). See UM2131 §5.2 Firmware update.
