Release Notes for FP-SNS-SMARTAG2 Software for STM32

Copyright © 2023 STMicroelectronics

Purpose

The FP-SNS-SMARTAG2 is an STM32Cube function pack. Thanks to this package you can read the ambient light, motion and environmental sensor data on your IoT node by the means of an NFC enabled reader, such as a mobile phone or tablet, throught a suitable AndroidST or iOST application such as the ST Asset Tracking (Version 3.1.0 or higher) and ST NFC Sensor (Version 1.3.0 or higher). The package supports battery operated use cases and energy harvesting mode. This software together with the suggested combination of STM32 and ST devices can be used, for example, to develop tracking, cold chain, medical, smart sensing and smart home/city/building applications. The software runs on an ultra-low power STM32L4 microcontroller and includes drivers for the Dynamic NFC tag and for the ambient light, motion and environmental sensors, as well as on the STEVAL-SMARTAG2 evaluation boards.

The expansion is built on STM32Cube software technology to ease portability across different STM32 microcontrollers.

FP-SNS-SMARTAG2 software features:

• Complete firmware to access data from an IoT node with dynamic NFC tag, environmental, motion and ambient light sensors

• Compatible with the STAssetTracking application for Android/iOS for reading data logs from the NFC tag and for sending them to the DSH-ASSET RACKING cloud-based dashboard

• Compatible with the STNFCSensor Application for Android/iOS for reading and setting the data Logs

• Sample implementation available for the STEVAL-SMARTAG2 evaluation board

• Easy portability across different MCU families, thanks to STM32Cube

This firmware package includes Components Device Drivers, Board Support Package and example application for the STMicroelectronics:

• STEVAL-SMARTAG2 (SmarTag2) evaluation board that contains the following components:
  • MEMS sensor devices (LPS22DF, STTS22H, LIS2DUX12, H3LIS331DL, LSM6DSO32X)
  • ambient light sensors(VD6283TX)
  • dynamic NFC tag (ST25DV64KC)

For each board support, this package contains the following projects:

• Example:

  • OneShot: reads in energy harvesting mode the ambient light and environmental sensor data on your IoT node by the means of an NFC enabled reader, such as a mobile phone or tablet, throught a suitable AndroidST or iOST application such as the ST NFC Sensor.
  • SimpleBootLoader: apply the firmware updated replacing the current running firmware with the new version received via NFC or runs the current firmware if the new version is not available.
  • SmarTag2: reads the ambient light, motion and environmental sensor data on your IoT node by the means of an NFC enabled reader, such as a mobile phone or tablet, throught a suitable AndroidST or iOST application such as the ST Asset Tracking.

• Applications:

  • FirmwareUpdate: it saves the new firwmare received via NFC using the ST FTM protocol and saves it on the right flash region and works with the SimpleBootLoader example for enabling the Firmware Update capability.
