I am sure there are a number of elegant ways of cleanly getting external sensor data (e.g. external air temperature) into the data-flash logs and or mavlink streams by modifying the code and integrating things properly.
However, as a very quick and dirty “bodge” without having to delve into the core code. Has anyone managed to feed a single or multiple sensor data into a pixhawk/ardupilot, perhaps using an unused sensor message such that it gets stored in the data-flash logs and is visible on mavlink? Doesn’t matter what the field is called…
Just need to find a currently existing sensor input that won’t directly affect the flight control…
