Another example of this is with 'Windows Mixed Reality' VR headsets. The controllers connect with the computer via Bluetooth and will often be noticeably laggy or unreliable when using onboard Bluetooth due to interference from other devices on the motherboard. Switching to an external Bluetooth dongle on a USB extension cable results in significantly improved controller tracking, and this issue is partly to blame for the poor reputation of WMR controller tracking.
They also didn't use it to connect to the controllers. They used two nRF24L01 transceivers which use Nordic's proprietary shockburst protocol. Easier to set up and better latency.
Yeah, the second-gen[1] Samsung Odyssey+ headset likewise has a built-in dedicated receiver in the headset and it's a significant improvement over the first gen. (I like the first gen better in practically every other way though.)
[1] There's much debate about what 'first gen', 'second gen' actually mean in terms of VR, I just mean it's Samsung's second WMR model after the Odyssey HMD.
