DJI supports Betaflight's flavor of MSP protocol which is in many aspects different from INAV flavor. To avoid introducing more complexity to already complex MSP code (3500 lines long, very hard to follow) this PR creates a subset of DJI-compatible MSP API and exposes it via a dedicated serial function (enable via CLI with
serial N 2097152
).In addition this PR introduces a new SBUS_FAST protocol (SBUS with 200k baud rate, corresponds DJI's fast serial link).
Still TODO:
This supersedes #5289. Also many thanks to @idavidstory for creating bridging the gap while I was arranging better collaboration with DJI folks.
