send-status-text.py

"""
    If you have a companion computer on your vehicle, you can send a status text
    message from the companion computer to the GCS using the MAVLink protocol to
    inform the user of the status of the process running on the companion computer.

    This is useful for debugging and for creating and sending messages to the GCS
    that are not part of the standard MAVLink protocol. And also the companion
    computer uses the MAVLink protocol and underlying infrastructure.

    This example assumes that you have a companion computer on your vehicle and
    that you have a UDP connection between the companion computer and the GCS.

    Device string for UDP connection: "udpout:127.0.0.1:14560" means that the
    companion computer acts as a source component (like the autopilot on the
    MAVLink connection) and sends messages to the GCS on the local machine.

    At the ardu-sim.sh, replace the "--out 127.0.0.1:14560" with "--master 127.0.0.1:14560"
