Introduction

This document is a guide for the SDK provided to help develop devices based on the LSM100A LoRa/Sigfox module of Seongji.

The LSM100A is a state-of-art module integrating STMicroelectronics’ STM32WL. It is very less current consumption for IoT device to extend battery life. And, it also supports both of technologies – Sigfox and LoRa – with LSM100A module itself.

You can switch Sigfox or LoRa with it so that you can also reduce cost. It is highly optimized for IoT solution (Low-Power Consumption, Low-Cost)

For other information, please refer to the document in Document.

Build using the STM32CubeIDE

1. Execute the .project file in Projects\NUCLEO-WL55CC\Applications\LoRaWAN_Sigfox\LSM100A\STM32CubeIDE folder.
   

2. After STM32CubeIDE is executed, LSM100A_SDK_LoRaWAN_Sigfox project is created in the left Project Explorer tab.
   The program name is subject to change.
   

3. Run Build All from the Project menu. After the build is completed, a hex file is created in the Release folder.
