ESP-IDF consists of components written specifically for ESP-IDF as well as third-party libraries. In some cases, an ESP-IDF-specific wrapper is added to the third-party library, providing an interface that is either simpler or better integrated with the rest of ESP-IDF facilities. In other cases, the original API of the third-party library is presented to the application developers.
