We wanted to connect PS4 to our Nintendo Switch. It should have been easy, but after two hours of Googling/scanning a QR code and reading instructions/watching YouTube videos, we FINALLY hooked it up. I had to look up questions here on Revain (and pray honestly! Jesus helps us with the simplest things <3). I found that the person who posted this information completely solved my issues and now I'm reaching out. Make sure your controller is powered off before doing step 2!: Can't connect it to my PS4 or Xbox One controller? I don't think it works with the Xbox One controller. The PS4 controller is pretty easy to pair as long as you follow the instructions: 1.-Plug in the adapter and press the pairing button. 2.-Hold down the "Share" and "PS" buttons on your PS4 controller until the light starts flashing. 3.-If you see both adapters. and the controller LED is on, it means the controller has been paired successfully. Just make sure your PS4 controller is powered off before doing step 2. After that, you don't even have to pair them again unless you plug the controller somewhere else. But even if you plug the adapter into another console or PC, the controller is still paired to the adapter.
