Is there any way I could connect my PC and Xbox one controller wirelessly without any additional adapters or hardware?
Why is there no wireless PC emulator for xbox controller? PS has got one. Xbox's suppose to be easier to make because of the SDKs that microsoft provides.
Xbox 360 and Xbox One controllers use a propriety wireless standard. This allows Microsoft to control and license who makes wireless peripherals for Xbox.
It also means these peripherals can only connect via wireless to an Xbox. Anything else requires an adapter to authenticate it's a valid and translate the data to and from that peripheral.
On the other hand, PlayStation controllers use Bluetooth, which should work with a PC, laptop, tablet, etc without additional hardware.
