This is the documentation for the latest (main) development branch of Zephyr. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

Networking APIs

Zephyr provides support for the standard BSD socket APIs (defined in include/zephyr/net/socket.h) for the applications to use. See BSD socket API for more details.

Apart of the standard API, Zephyr provides a set of custom networking APIs and libraries for the application to use. See the list below for details.

Note

The legacy connectivity API in include/zephyr/net/net_context.h should not be used by applications.
