ESP-IDF Documentation

FujiNet is built on Espressif's "IoT Development Framework", or ESP-IDF for brevity. Note that the documentation web site defaults to the latest available version of the framework, and this is sometimes a pre-release version not yet available to PlatformIO users. Make sure you choose the "latest stable" version from the menu hidden at the bottom-left of the page. The "latest prerelease" version is usually chosen by default.
