Problem Retroarch and XBOX Controller - Not configured, fallback option activated

[Der Barde aus dem Tale]

 

I have installed Atari 2600 games in Launchbox. I use Retroarch and the game I want starts without any problems.I have a Bluetooth XBOX controller. It is recognized in the windows control panel.It is selected and activated in the launch box options. In Retroarch in the Port 1 Controller it is in the device index as an input device. The following error message always occurs: "Not configured, fallback option activated". No matter which game I play, no button on the controller provides any feedback. What am I doing wrong?

The solution is to purchase the official Microsoft Xbox Wireless Adapter for Windows 10.  

The controller does not always work via the Bluetooth connection.
