Summary

With this project, we have completed the part where we explore the wireless connectivity capabilities of ESP32. For IP networks, ESP32 can connect to Wi-Fi. When we need to set up a WPAN to exchange data between devices, it supports BLE mesh networking. As we discussed earlier, IoT cannot be defined without connectivity and communication considerations. In this chapter, we gained important hands-on experience with the networking capabilities of ESP32, which we can leverage in any real-life IoT project.

The next chapter is devoted to cloud platforms and services, and how we utilize ESP32 as an IoT device in cloud solutions to interact with the physical environment remotely. Integration with cloud platforms and services closes the loop for any IoT solution, where all devices can be accessed from anywhere in the world and data coming from those IoT devices is stored for further processing.
