Introduction
This document shows how to perform power measurements on X-CUBE-SUBG1 (version v3.1.0 or higher) expansion software
for STM32Cube and check its power improvement over previous versions, with respect to 6LoWP
AN applications.
Low power optimization has been added from version 3.1.0 to better support battery-operated devices.
Although X-CUBE-SUBG1 supports different hardware platforms, only the NUCLEO-L152RE development board equipped with
the X-NUCLEO-S2868A1 expansion board has been taken into consideration for this study.
