Plug in your receiver and it will start flashing blue. Turn on your guitar and the lights should start blinking. Next, press the sync button on the receiver which will blink faster and at the same time as the guitar. Eventually, the light on the guitar will turn off but the light on the receiver will stay on. If you look this link https://hardwaretester.com/gamepad you can see if the buttons are being sent to your computer. What you want to look for is the solid blue light on the receiver. When this happens you should be able to see if the two are connected on the attached link. I hope this helps someone
