Introduction

FP-SNS-SMARTAG1 is an

STM32Cube function pack which allows you to read the motion and environmental sensor data on

your IoT node via an NFC enabled reader such as a mobile phone or a tablet. The package supports energy harvesting

(enabled by NFC) and battery operated use cases.

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 and building applications.

The software runs on an ultra-low power STM32L0 microcontroller and includes drivers for the Dynamic NFC tag and for the

motion and environmental sensors.

1.1 Overview

The key features of the FP-SNS-SMAR

AG1

package are:

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

sensors

• Ultra-low power operations, with the support of energy harvesting and battery operated use cases

• Compatible with the ST SmarTag application for Android/iOS for reading and displaying sensor data

• Sample implementation available for the STEVAL-SMARTAG1 evaluation board, and for the X-NUCLEO-

IKS01A2 and X-NUCLEO-NFC04A1 expansion boards connected to a NUCLEO-L053R8 development

board

• Easy portability across different MCU families, thanks to STM32Cube

• Free, user-friendly license terms

This software tracks temperature, pressure, humidity and vibration values in a fixed time range and sends them

via NFC. Using an Android or iOS device the logged data can be monitored/displayed.

The software gathers:

• the temperature, humidity, pressure, and vibration sensor drivers for the HTS221

, LPS22HB, LSM6DSL,

LSM303AGR and ST25DV04K devices for the X-NUCLEO-IKS01A2 and X-NUCLEO-NFC04A1 expansion

boards connected to a NUCLEO-L053R8 running on STM32.

• the temperature, humidity, pressure, and vibration sensor for the HTS221, LPS22HB, LIS2DW12 and

ST25DV64K devices for the STEVAL-SMARTAG1 evaluation board running on STM32.

1.2

This package is compatible with the ST SmarTag Android/iOS (Ver. 1.0.0 or higher) application available at the

respective GooglePlay/iTunes store, which can be used to display information sent via dynamic NFC/RFID tag

protocol.

Architecture

The STM32Cube

function packs leverage the modularity and interoperability of STM32 Nucleo and X-NUCLEO

boards, and STM32Cube and X-CUBE software, to create function examples, embodying some of the most

common use cases, for each application area.

These software function packs are designed to exploit as much as possible the underlying STM32 ODE hardware

and software components to best fit the requirements of final users’ applications.

Moreover, function packs may include additional libraries and frameworks which do not present the original X-

CUBE packages, thus enabling new functionalities and creating a real and usable system for developers.

STMCube™ is designed by STMicroelectronics to reduce development effort, time and cost across the entire

STM32 portfolio.

STM32Cube version 1.x includes:

• STM32CubeMX, a graphical software configuration tool that allows the generation of C initialization code

using graphical wizards.

• A comprehensive embedded software platform specific to each series (such as the STM32Cube for the

STM32 series), which includes:

– the STM32Cube HAL embedded abstraction-layer software, ensuring maximized portability across the

STM32 portfolio

– a consistent set of middleware components such as RTOS, USB, TCP/IP and graphics

– all embedded software utilities with a full set of examples

To access and use the sensor expansion board, the application software uses:

• STM32Cube HAL layer: provides a simple, generic and multi-instance set of generic and extension APIs

(application programming interfaces) to interact with the upper layer application, libraries and stacks. It is

directly based on a generic architecture and allows the layers that are built on it, such as the middleware
