Please provide a copy of your Full Parameter File in a text file.

What receiver are you using on your rover?



I use a normal receiver with PPM encoder.


Actually,I use APMRover on a dual motor boat.I think it can work like a skid steering rover.When I had uploaded the mission first time it worked.Then I switched to Manual and I haven't able to return to Auto since.Except Auto becomes RTL ,other modes are effectual.

Could you provide a copy of your dataflash log file when you go into auto and the vehicle RTLs?

Thanks, Grant.

Thanks a lot !! My log file is too large to upload. I intercept a section of it. I will send an e-mail to you if you need.


Make sure you Restart the mission each time you run it.

Your mission is unusual.  Your second mission item is a takeoff command.  Your in a rover right?  Then you have a bunch of spline waypoints which rover will also ignore followed by an RTL command.  I suspect Rover is ignoring all the other waypoints and the first thing its doing is an RTL as its the first one it understands.

I have attached your mission so you can confirm.

Thanks, Grant.
