API COMMANDS OVERVIEW
API commands are mainly classified into the following types.
• gbconfig: manages the configurations of the device
• gbcontrol: controls the device
• gblayout: adjusts the features related to the screen layout
• Event: message from the device to report that the device’s state changed
Command syntax uses the command type followed by a space, two dashes, and then the command
plus the argument (as needed). For example:

This example changes the device’s configuration to be “normal” for the mode of the camera.
Note: For the “show” command there is only a single dash: gbconfig -s camera-mode
