I asked a similar question in the past.

> Great question! We’ve definitely had some interesting discussions internally about CBOR. It’s not really applicable right now, but we may have uses for it in the future. Either way, you can be confident that our whole user experience goal with respect to things like payload format is to do the research, compare our options, make the hard decisions, and do the difficult implementation work so that you don’t have to! You can see all the CoAP code in the [Device OS](https://github.com/particle-iot/firmware) communication folder. Many of ou…
