How to programmatically (via arduino) change the direction of rotation of a brushless motor?

Question

Arduino

There is a brushless, controlled by the controller. The controller cannot change the direction of rotation.
What is the best way to implement this through arduino - do a mechanical rearrangement of two wires to the motor through a relay, or take 2 controllers, set them to rotate in different directions, and turn on the one you need?

Answer 1

put a controller that can change the direction of rotation.
or read the documentation. changing direction is a simple task - even the simplest controllers can do it.
