Settings View
The Settings View is used to configure the settings for the QGroundControl application (rather than a specific vehicle). You do not have to have a vehicle connected to change these values.
You can switch between the various settings options by clicking the buttons in the left-sidebar.
Settings Options
General
The main application configuration settings. These are used to specify: display units, autoconnection devices, video display and storage, RTK GPS, etc.
Comm Links
Allows you to manually create communication links and connect to them. Keep in mind that normally this is not needed since QGroundControl will automatically connect to the most common devices.
Offline Maps
Allows you to cache maps for use while you have no Internet connection.
MAVLink
Settings associated with the MAVLink connection to a vehicle.
Console
Used to capture application logs for help with diagnosing application problems.
