I’ve had connectivity and reliability issues when using Bluetooth controllers with my Steam Deck docked anyway. It’s Bluetooth only seems good for using headphones while handheld for me. I got a 10ft USB extenders and 4 port hub for controllers and it works perfectly and is much easier than having to pair all controllers, make sure they’re all charged, etc.
