New MAVLink packet send over USB but not over telemetry

Hi everyone,

I added some modifications to ardupilot and MissionPlanner in order to add a new MAVLink message. Everything is working perfectly when I test with MissionPlanner connected to my autopilot (Cube Orange) in USB. However, when I connect in telemetry (RFD900x), the packet is not received by MissionPlanner (every other packet is received properly, and mission planner/ardupilot works properly).

I have no idea why this works over USB but not when using telemetry.

Thanks for your help,

Nicolas

Do you have a link to your source code changes? That would help in diagnosing the issue.
