There is an easier way to control your BlueROV.
Instead of carrying a bulky PC with QGroundControl you can use your iPad.
BlueROV Control is an app with an intuitive user interface and all the features you need.
You can use an on-screen joystick or connect Bluetooth Game Controller (preferred).
It now supports BlueOS from Blue Robotics and also connects to Newton Gripper and Ping1D, Ping360 sonars.

Please see the Help section in the app for connection setup.

You can use all features of Blue Control for free except video recording.
