"Take a look at http://ardupilot.github.io/MAVProxy/html/development/mavcustmod.html for an example of a MAVProxy module.

Note the "init" function must return an instance of the module. For example "return ModuleName(mpstate)". That is most likely…"

"I think the Autotune_axes were added in after version 3.2.1

The wiki covers the latest version of Arducopter (3.4.4), so if you're using an older version the documentation will not be accurate."

"It's a bug in MAVProxy - you can't load waypoints via the --cmd="wp load mission.txt".
There's a bug report at https://github.com/ArduPilot/MAVProxy/issues/142"

"Mission Planner (like all GCS's) sends heartbeat messages to the UAV. Not sure if there's a way to disable it.
Why do you require Mission Planner between the UAV and MAVProxy? MAVProxy can talk directly to the UAV.
I had a quick look at your script…"

"You can use events in Python to run a specific function when data is received over serial or UDP, instead of checking continuously. It's more complex to build this way though.
You can get MAVProxy to automatically load your module on startup by…"

"That is definitely possible. You will need to write a MAVProxy module to do so. I recommend starting with a copy of the serial module (linked in my previous reply) and editing it from there.
There's some documentation on developing MAVProxy modules…"

"The best way would be to create a MAVProxy module, based on the serial module (https://github.com/ArduPilot/MAVProxy/blob/master/MAVProxy/modules/...)."

"The site http://qgroundcontrol.org/mavlink/start has a list of flight controllers that use mavlink.

Yes, you should be able to mix different flight controllers with different ground stations. One note though, some flight controllers have a few…"

"The wiki has undergone significant changes in the last 4 years! Hence the changed link.
