Help¶

This variable specifies time in milliseconds after which DTLS connection is considered dead by TLS server and DTLS resources are freed. This is needed to prevent situation when DTLS client shuts down without closing connection gracefully, which can prevent other peers from connecting. Value of 0 indicates no timeout - resources will be freed only when connection is gracefully closed by peer sending TLS notification or socket is closed.

Direct dependencies¶

NET_SOCKETS_ENABLE_DTLS && NET_SOCKETS && NETWORKING

(Includes any dependencies from if’s and menus.)

Defaults¶

5000 if NET_SOCKETS_ENABLE_DTLS && NET_SOCKETS && NETWORKING
