Hi,
This topic is related to the MAVLink topic Rejecting mission request command component or system ID mismatch (Rejecting mission request command, component or system ID mismatch).
@Alp_Ucan , proposed me to open a topic on this instance here.
It seems that the latest QGC versions (4.4.1 and 4.4.2) use another method for mavlink packet generation compared to version 4.3.0. Because when I want to execute a mission, which is uploaded with a geofence directly from QGC to the drone, I receive these errors with the latest QGC versions. However, with version 4.3.0 the errors are not there.
Maybe something to add to the open issues list.
Best, Quincy
