I have been trying to upload the survey waypoint in terrain frame altitude type in Qgcs Android version 4.2.9 but its not uploading waypoint and giving below errors.
When i try with MP its works normally without any issue.
Terrain pending also 0.
Could you uploaded a dump of your parameters? Have you set the TERRAIN_ENABLE parameter to 1?
Try it with Mission Planner and see if you are able to upload through that.
