Hi,
my setup is S900 , A2, dji OSD Mark II and 900 mhz datalink. Pc GS is connecting , i draw mission then i try upload it but  "Upload Failed because of Timeout " error message .. any suggestion? Thanks

I have flown many autonomous missions using a Windows 7 laptop without any problems.

The other day i tried my MS Surface Pro 3 with Windows 8.1.

Everything went fine until I attempted to upload the waypoints, then I got that same message.

I noticed that the COM port didn't show as it usually did, but seemed to work fine.

I reworked everything with my normal laptop and flew the mission.

My hope is to try the Surface again on the bench to see if I can find any changes to get it to work.

If I find anything I'll repost

The only thing I can suggest is to watch that COM port to make sure it doesn't change after you first connect.
