FP-SNS-SMARTAG1
Software Overview 9
Software Description
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 Product summary drivers for the Dynamic NFC tag and for the
motion and environmental sensors.
Key features
•Complete firmware to access data from an IoT node with dynamic
NFC tag, environmental and motion sensors
•Ultra-low power operations, with support of both energy harvesting
and battery operated use cases
•Compatible with the ST NFC Sensor application for Android/iOS, to
read and display sensor data
•Sample implementation available for the STEVAL-SMARTAG1
evaluation board, and for the X-NUCLEO-IKS01A2 (or X-NUCLEO-
IKS01A3) 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 term

(Pin1)
•In order to program the board you need to connect an
external ST-Link to the SWD connector on the cradles with a
6pin flat cable or directly.
•The easiest way is to get an STM32-Nucleo board which
includes an ST-Link V2.1 programmer
•Be sure that CN2 Jumpers are OFF and connect your STM32
Nucleo board to the ST NFC SensorTag through the provided
cable paying attention to the polarity of the connectors. Pin 1
can be identified by a little circle on the PCB silkscreen
(STM32 Nucleo and ST NFC SensorTag board).
NOTE
The battery must be present in order to use the ST-Link features (programming, debugging and serial communication)

NOTE
UART is not available on STEVAL-SMARTAG1 using binary generated by System Workbench for STM32 (due to flash size constraints)
NOTE
For having the UART functionality on to STEVAL-SMARTAG1
board, it is necessary:
- To recompile the code uncommenting the line
//#define SMARTAG_ENABLE_PRINTF
on file: Projects\STM32L031K6-
SmarTag1\Examples\SmarTag1\Inc\SMARTAG1_config.h
- To connect the BLUE (USART2_TX) cable to the RX pin on the

•In addition to the default mode, there are two different logging mode that can be chosen:
•Log only out of range [min, max] and accelerometer events:
•the selected data will be logged only if a minimum or maximum threshold value will be matched (sync events).
•logging only if a wake up or change of orientation events occurs if enabled (async events)
•Force logging of one sample:
•the current value of the selected data will be logged, after that the data logging re-starts with the previous
