Summary

In this first chapter, we discussed what the Internet of Things (IoT) is in general and its building blocks to understand the basic structure of IoT solutions. One of the building blocks is device hardware that interacts with the physical world. System-on-chip (SoC) is a major component while designing an IoT device. Espressif Systems empowers us, as IoT developers, with its ESP32 product family, which includes many SoCs with different configurations in response to the needs of IoT projects. In addition to hardware, Espressif maintains the Espressif IoT Development Framework (ESP-IDF), the main software framework to develop IoT applications on ESP32 SoCs. ESP-IDF comes with all the necessary tools to deliver full-fledged IoT products. We also talked about real-time operating system (RTOS) options that we can select from in ESP32 development. ESP-IDF integrates FreeRTOS, a prominent RTOS option in the embedded world, as a component.
