A complete IoT embedded and software roadmap

In Chapter 1, we discussed the IoT four-layer architecture, including the sensing, networking, data processing, and application layers. The first three chapters explained the sensing layer of IoT, in which we learned about the communication protocols used by sensors and how to interface different sensors with ESP32. Chapter 4 explained network protocols such as Wi-Fi, Bluetooth Low Energy (BLE), and cellular communication, and in Chapter 5, we learned about data protocols such as HTTP, MQTT, and Webhooks. Furthermore, we completed three projects that explained how data is processed, manipulated, and presented in the form of visualization. This cumulative approach lays a robust foundation for IoT development.

Moving forward from our foundational discussions, this section unveils a complete IoT roadmap, carefully crafted by considering various job requirements in these fields. The roadmap is neatly split into two categories: IoT embedded...
