Summary

In this chapter, we delved into various connectivity options that allow us to establish connections between the ESP32 and diverse networks. We delved deep into the Wi-Fi and BLE protocols, performing hands-on exercises to grasp their practical applications.

However, there are scenarios where these options might not suffice or are unavailable. To address such situations, we expanded our knowledge to encompass cellular communication and the LoRaWAN protocol. These additional protocols empower us to broaden the ESP32’s connectivity by leveraging external modules.

In the forthcoming chapter, we’ll take a closer look at data-based protocols. This exploration will shed light on how we can effectively exchange data across different devices using these network protocols.
