MAVLink Support

Micro Air Vehicle Link communication protocol, dialects and messages

The Micro Air Vehicle Link (MAVLink) communication protocol is a message protocol for sending and receiving messages between UAVs. The protocol uses a publish-subscribe pattern for data streams with specified topics and message types. There are different sub-protocols for missions and parameters. Use the MAVLink supported functions to specify predefined or custom dialects, setup clients, and send or receive messages.

Functions

`mavlinktlog`	Read MAVLink message from TLOG file
`mavlinkio`	Connect with MAVLink clients to exchange messages
`mavlinkclient`	MAVLink client information
`mavlinksub`	Receive MAVLink messages
`mavlinkdialect`	Parse and store MAVLink dialect XML

Blocks

MAVLink Blank Message	Create blank MAVLink message bus by specifying payload information and MAVLink message type
MAVLink Deserializer	Convert serialized `uint8` MAVLink data stream to Simulink nonvirtual bus
MAVLink Serializer	Serialize messages of MAVLink packet by converting Simulink nonvirtual bus to `uint8` data stream

Featured Examples

Visualize and Playback MAVLink Flight Log

Load a telemetry log (TLOG) containing MAVLink packets into MATLAB®. Details of the messages are extracted for plotting. Then, to simulate the flight again, the messages are republished over the MAVLink communication interface. This publishing mimics an unmanned aerial vehicle (UAV) executing the flight recorded in the tlog.

Tune UAV Parameters Using MAVLink Parameter Protocol

Use a MAVLink parameter protocol in MATLAB and communicate with external ground control stations. A sample parameter protocol is provided for sending parameter updates from a simulated unmanned aerial vehicle (UAV) to a ground control station using MAVLink communication protocols. You setup the communication between the two MAVLink components, the UAV and the ground control station. Then, you send and receive parameter updates to tune parameter values for the UAV. Finally, if you use QGroundControl© as a ground control station, you can get these parameter updates from QGroundControl and see them reflected in the program window.
