Right now, I am struggling with getting the sub and copter to work together in QGC. When I have both connected, and if arducopter was the first to be connected, then the interface looks normal, and I am able to switch to ardusub. However, if I am connected to the sub first, or if I switch to the sub from the copter (vehicle 1 to vehicle 2), the drop-down bar in the top for switching between vehicles disappears, and I am unable to switch back to the copter for planning. Here is a screenshot.
The screenshot is from QGC v4.0.5, the latest version that has been tested with Ardusub. However, even in the current stable release, I have the same problem. Please excuse the GPS locations of the drone and sub being in different continents, I am working inside where it doesn’t matter quite yet.
A little more info, I have the sub connected through an ethernet cable, then the drone with an esp8266. I turned off auto-connecting, and I go to the Comm Links settings page to connect both.
Is this a bug, or am I doing something wrong in QGC?
