Mission transfer failed, Retry transfer. Error. Vehicle returned error: X/Param5 has invalid value (MAV_MISSION_INVALID_PARAM5_X) Param5: nan

Any idea why I cannot upload missions from QGC to the drone since firmware updates? Same error with Geofence etc.

Also get an audio message about Mavlink?

Thanks in advance.

OK, I think I have managed to sort it.

In the Herelink QGC app I had to add a Com link, UDP Link on port 14551.
The missions now seem to upload and sync.

Is this correct?
