Communicating with ODroid via MAVLink¶ Overview ¶ This page introduces how to connect and configure an ODROID U3 , ODROID-C1+ or ORDOID-XU4 so that it is able to communicate with a Pixhawk flight controller using the MAVLink protocol over a serial connection. If a serial port is given (for example a radio device connecting an airbourne MAVProxy instance with the GCS), a link-specific baud rate can be given after the device, delimited by a comma. The Fly Mission example shows how to create, upload, and run, pause, and restart missions using the SDK. A serial connection is used to connect Joystick/Gamepad hardware via QGroundControl. Although the MAVLink spec defines a standard communication protocol to communicate with a vehicle.
