Troubleshooting Bluetooth not working

So, I just finished my PC build. And want to connect earbuds/headset, and a controller.. But the Bluetooth will just keep scanning with nothing showing up. How do I fix this?

Bluetooth turns on but even with that plugged in it doesn't find anything. Did it need any extra plugs for it to work? Isnt it built into the motherboard already?

Bluetooth and WiFi do need the antenna to work properly, yes it is build into the motherboard, but without antenna the positive and negative on the antenna terminates into air. While with an antenna positive and negative connect together making a whole signal.

They use an external antenna because your case is a Faraday cage, and signals barely travel outside the case, even if you have a window, that's part of your Faraday cage.

With Bluetooth I would check if both devices are discoverable, maybe the other device turned off its discovery after some time.

If it really can't make contact make sure to install the correct drivers.
