I really hope you guys can help us with this, we have searched everywhere but can’t seem to find an answer for this. So we are planning to use Ardusub on or boat (not a sub), and the reason we are thing of using Ardusub instead of Ardurover/Arduboat is that are no support for use virtual joystick in qgroundcontrol. That way we don’t need an RC, but only a SIK radio. The boat will be in Auto mode 99% of the time.
But we can’t switch to any flight mode that use GPS. In qgroundcontrol for Windows we can see this modes but don’t switch to any of them. In qgroundcontrol for Android these modes doesn’t even show up. And we have 3d lock and all pre-flight check are ok. And because this is a regular boat we use a regular GPS (neo 8). Are there any parameter or so u have to change to use GPS mode in Ardusub, or anything else that need to be done to use GPS? Or what are we doing wrong, hope u guys have an answer for us, I would really appreciate it. I can mention that when we tried Ardurover there no problem switching to GPS flight modes, so there seems that the hardware are okay.
