| |
| Applications should use the BSD socket API defined in |
| :file:`include/net/socket.h` to create a connection, send or receive data, |
| and close a connection. The same API can be used when working with UDP or |
| TCP data. See :ref:`BSD socket API <bsd_sockets_interface>` for more details. |
| |
| See :ref:`sockets-echo-server-sample` and :ref:`sockets-echo-client-sample` |
| applications how to create a simple server or client BSD socket based |
| application. |
| |
| The legacy connectivity API in :file:`include/net/net_context.h` should not be |
| used by applications. |
