Abstract

The goal of this thesis is to create a dynamic mesh network using ESP32 microcontrollers for IoT and sensor networks. The mesh consists of several nodes interconnected in a tree structure and is able to overcome node failures. This is fulfilled by creating a new mesh solution that is able to operate with and without an Internet connection. The use of MicroPython enables asynchronous operations to be run in a non-blocking manner. The project is built on top of two protocols, proprietary ESP-NOW and common WiFi. The solution brings possibilities for quick mesh application development, but it is limited by memory consumption. The functionality was tested by the creation of a demo application with three practical scenarios for home use.
