Figure 4. Fp-Sns-Smartag2 Uart Output Initialization - ST STM32Cube User Manual

When you first press the reset button, the application:
• starts initializing the UART and I²C interfaces
• shows the SmarTag UID
• reads the last configuration written on to NFC tag (if available)
• sets the NFC behavior
• sets the wakeup timer
After the auto-start range time, the samples are logged using the written configuration on the NFC tag (or the
default one, if not available).
