Tiivistelmä
The thesis project was performed at Hitachi High-Tech Analytical Science with the goal of utilizing AWS IoT Device Shadow in their embedded instruments without dependence on AWS SDK via MQTT protocol.
The project involved three subsequent stages: making a Python prototype, implementing the client library in C++, and testing the library on an embedded Linux system. The C++ library was stacked with Paho MQTT client and other open-source libraries such as JSON for Modern C++ and Boost.
As a result, the thesis delivered positive outcomes and a working library in which MQTT connection and shadow handling functionalities are well implemented and tested. The thesis project did not cover all MQTT 3 and new MQTT 5 specifications but instead focused on device shadow features, therefore the library still had some limitations in functionalities. From the company side, the thesis will be used as a fundamental research step and will be refactored and improved before integrating into their embedded system.
