I'm learning about and testing various "IoT" communications schemes. I'm curious if any other Nim peoples have any experience with various IoT protocols?
In particular, I've been reading up on CoaP. It uses UDP packets which can be nice on some embedded devices or networks where TCP is a bit heavy. MQTT is really popular but doesn't fit my targeted use cases very much (internal m2m communications, off grid deployment, etc). gRPC seems like a possibility but appears to require a fully HTTP2 compliant web server.
Anyone else know of any good protocols, or interested in a Nim CoaP library?
