New XBOX Series Wireless Controller's trigger not working (PC/Bluetooth)

The Bluetooth controllers don't come with an adaptor, is has Bluetooth built in. The device it connects to need to have Bluetooth to work, if your PC doesn't then you need to get a Bluetooth adapter for the PC.

The wireless part of the controller works on a unique frequency only for the xbox controllers, so it won't work with WiFi, so for your PC to use the Xbox Wireless part, you would need the Xbox Wireless Adapter.

Hi,

The Answer Is Yes as Long As it has Bluetooth or wireless connection

Hi,

That's not quite right. Apologies for quoting you.

The Xbox 360 controller uses a proprietary wireless technology, it's not Bluetooth and the old adaptors won't work with a modern controller like the Xbox One or Series X|S controllers.

Unlike Xbox 360 wireless controllers, Xbox One and Series controllers can also be connected via USB cable. Old Xbox One controllers use Micro USB, Series Controllers are USB C.

To use an Xbox One/ Series controller via wireless on a PC and get basic functionality, all you need to do is connect the controller via Bluetooth. If your PC doesn't have Bluetooth then you'll need to buy a Bluetooth USB dongle, they're very cheap, less than $10. I'm from the UK and I connect my Series X controller to my PC via BT dongle I purchased from Amazon for about £5.

For extra wireless features you'll need the Xbox One Wireless Adaptor for Windows 10. Unfortunately, the official Microsoft branded adaptors are now quite rare.

it uses wifi that the xbox has a receiver and sender for, similar to the microsoft pc wireless adapter but obviously built into the console.

no bluetooth at all. there is not a single bluetooth chip in the console, the modern xbox controller connect via wifi to the console or bluetooth to phones and pc if not using the adapter for pc. only the controller has bluetooth and this is basic at best.

Does the Xbox Series X or Series S support Bluetooth? | Windows Central

No Bluetooth for Xbox Series X

The Xbox Series X doesn't have Bluetooth, similarly to the Xbox One, Xbox One S, and Xbox One X. The reason is simple; the Bluetooth signal isn't strong enough to meet Microsoft's specifications for latency. Microsoft uses its proprietary signal, dubbed Xbox Wireless, for connecting controllers and other accessories, like the Turtle Beach Stealth 600 and the SteelSeries 9X wireless headsets.

Microsoft's signal is far stronger than Bluetooth. Since many people typically game while sitting far away from their consoles in the living room or so on, Bluetooth's susceptibility to interference increases exponentially at longer ranges. If you were hoping you could use a USB Bluetooth adapter, it wouldn't work either, as the Xbox Series X and other Xbox One consoles don't have the drivers necessary to power them.

This is a new installation but I'll try reinstallation.

Just an FYI, this is a known issue for Epic Games purchases of Hitman 3:

There are many other threads on Reddit, too. I thought that the issue would have been fixed from Xbox Game Pass, caught by a quality check for a Microsoft published platform but evidently this slipped through.

Hi,

The Series X|S and Xbox One controllers are not compatible with the old Wireless Gaming Receiver used to connect Xbox 360 wireless controllers to a PC device. However, they do support connection to a PC via Bluetooth.
