End a secure session

A client can end a session by either waiting for the timeout to expire or by ending it manually. To end a session, send a Secure Session Control - 0x2E to the local client device with bit 0 of the options field set and with no password.

The device ends the outgoing secure session with the node whose address is specified in the type 0x2E frame. This frame can be sent even if the node does not have a session with the specified address—the device will send a message to the specified server prompting it to clear out any incoming session data related to the client (this can be used if the server and client fall out of sync. For example, if the client device unexpectedly loses power during a session.

Sending a type 0x2E frame with the logout option bit set, and the address field set to the broadcast address will end whatever outgoing session is currently active on the client and broadcast a request to all servers to clear any incoming session data related to that client.
