#397: CON usage with CoAP over TCP In http://www.ietf.org/mail-archive/web/core/current/msg06988.html Timothy wrote: ---------------------------------------------------------- In section 4 Message Format says: The ’Message Length’ field is a 16-bit unsigned integer in network byte order. It provides the length of the subsequent CoAP message (including the CoAP header but excluding this message length field) in bytes (so its minimum value is 2). The Message ID and message type are meaningless and thus elided (what would have been the message type field is always filled with what would be the code for NON (01)). What would happen if an Application where to place a CON in the message type field. Based on my reading of this text I would expect the message type from the application to be ignored and the transport to put in a NON message. Is that correct? -- -------------------------------------+------------------------------------- Reporter: | Owner: draft-ietf-core-coap- Hannes.Tschofenig@gmx.net | tcp-tls@ietf.org Type: protocol defect | Status: new Priority: major | Milestone: Component: coap-tcp-tls | Version: Severity: Active WG Document | Keywords: -------------------------------------+------------------------------------- Ticket URL: <https://trac.tools.ietf.org/wg/core/trac/ticket/397> core <https://tools.ietf.org/core/>
