I finally find a solution. When you boot for the first time the controller cant be paired but when you shutdown and poweron the console you can pair the bluetooth official controller of Atari VCS. You need to use a keyboard or other controller to Open the recalbox option configure Control bluetooth and press your VCS bluetooth actuvation on controller. The controller works at all without any misconfiguration or problem.
This is a good console to use as recalbox machine, in case I use a USB pen with 32GB.
Maybe this info is good for other people.
