How to Configure an ESP Mesh Network using Arduino IDE – Communicate among and between ESP32, ESP8266, and NodeMCU

Internet of Things (IoT) has seen exponential growth over the past couple of years. A new study from International Data Corporation (IDC) estimates that there will be almost 42 billion connected devices within the year 2025, generating over 80 zettabytes (ZB) of data. As the number of IoT devices grows; the amount of data grows, along with that, grows the need for superior network instruments; which can support this load.

However, if we consider a common host (like a generic router), it can connect to a limited number of nodes, less than 32 to be exact. And with an increasing number of IoT devices that could be in our home or industry, this is not sufficient. Currently, there are two solutions to this problem: The first one is to use a Mesh Router that can handle a lot more connections compared to a generic one, or we can use a network protocol known as Mesh Network.
