The Core Protocol Working Group maintains an accepted standard specification for the Core Protocol and provides an open process for proposing, discussing, and accepting changes.

I only learned about this effort today. They seem to document the air protocol and the companion protocol, so that compatible implementations can be written to expand the universe of MeshCore nodes.

I’m not sure I agree with using ZephCore (a port of MeshCore to Zephyr RTOS, apparently initially AI-generated using Claude) as the reference material – as opposed to directly referencing the MeshCore mainline repo. But nevertheless, it’s a good start to formalizing the protocol behavior necessary for an interoperable implementation to those existing nodes in the field.
