Interfacing Pixhawk Cube Orange with Raspberry Pi for Status Text Communication

ArduPlane Plane 3.9
1

I want to send a “status text” message to Pixhawk Cube Orange through Mission Planner. Later, I want to read this status text message from Pixhawk Cube Orange using Raspberry Pi. Note: Raspberry Pi can communicate with Pixhawk via a USB cable.

The Cube orange produces Text messages but does not read them.
Take a look at lua scripting, it can probably do what you want.
But update to ArduPlane 4.3.6 before you do.
