SET UP
The PX4 firmware is the brains of your autopilot operation and Version 1.7 is already loaded on your Pixhawk 4.
To configure your vehicle as well as do mission planning and flight monitoring, you can use the free QGroundControl application (Windows, Mac, Linux),  which you can download from http://qgroundcontrol.com/
Once you have installed and successfully run QGroundControl, plugin Pixhawk 4 with the supplied USB cable, it should be automatically recognized. Click on and follow the on-screen instructions to finish the setup steps.
As part of a first time setup, you’ll need to configure some of the required hardware components, such as:

  •  Frame type  configuration
  •  Compass calibration
  •  Radio control calibration
  • Accelerometer calibration
  • RC transmitter mode setup
  • ESC calibration

In addition to mandatory calibrations, you may also choose to configure optional hardware including battery monitor, sonar, airspeed sensor, optical flow, OSD, camera gimbal, antenna tracker, etc.
