Summary

In this chapter, we have learned the fundamentals of application protocols for IoT networks, particularly those that are commonly used for IoT, including MQTT, HTTP, CoAP, and XMPP, and understood the considerations that are put in place when designing for a network. We looked at a practical use case of using an MQTT pub/sub client as part of deepening our understanding of it, and learned how to use cURL to send GET and POST requests to retrieve and send data to websites. Understanding these protocols and design considerations is paramount for anyone involved in developing or managing IoT networks as they ensure optimal communication, security, and data transmission across various devices and platforms. This knowledge is instrumental in developing efficient, secure, and scalable IoT solutions, thereby enhancing your ability to contribute effectively to IoT projects and innovations.

In the next chapter, we will be looking at understanding the use of communication and connectivity...
