Set param error: Please ensure your version is AC3.3+

I get the error: “Set param error. Please snsure your version is AC3.3+” even tho im using the latest firmware: ArduPlane: V4.3.5 & the latest mission Planner.

Is 4.3.5 > 3.3 ?

It’s not an error, it is a request.

You have complied with the request by using the latest stable version.

So pat yourself in the back and ignore it

What param are you trying to change?
