Overview

HTTP is one of the most widely-used application protocols over the internet. It provides a standardized and reliable way of data exchange between a server and a client. Being used in web browsers by millions of people on a daily basis, examining the structure of HTTP and how it can be used by nRF70 series devices for data exchange is crucial.

In this lesson, we will learn about HTTP and its structure. We will explain the main features of HTTP, including its requests structure and how a request is formatted to cater for a variety of web activities. We will also look at the HTTP library and learn how to enable support for both HTTP client and server functionalities using an nRF70 Series device.
