For an interoperable firmware update solution you need the following building blocks: a) A transport mechanism to get the firmware images from a repository to the clients. While this sounds trivial it is actually quite complex since you often need to know exactly what device you are dealing with to provide it with the appropriate image. Hence, this is a bit different to the way how software is updated on Linux-based systems with their package manager. b) You need a security wrapper that protects the actual firmware image. (c) Finally, you need information about the firmware image itself. Call it meta-data. We are using LwM2M, i.e., a CoAP-based RESTful API protocol for (a), for (b) you could use something like RFC 4108 (or similar). For (c) we have a bit of meta-data defined in the LwM2M spec and there is some info also defined in RFC 4108. We are suggesting to revisit RFC 4108 (b) and define additional meta-data (c). Does this make sense?
