To get the Bluetooth feature, you'll have to opt into the latest Steam Client Beta and choose to 'update firmware now,' as you can see in the image above. (In case the gamepad's receiver is also plugged in, you can easily switch between the two modes whenever you want.) Valve says the gamepad's BLE connection is 'excellent,' so it'll probably do the trick unless you're playing a game where you absolutely can't risk lags. You can use it even with devices that do have USB ports, though, in case you lose or forget the controller's tiny receiver. However, the option to connect via Bluetooth will enable you to use the gamepad with any mobile device or laptop without a USB port. The Steam Controller is actually paired with a wireless dongle, and Valve still recommends using it whenever possible, since it provides the fastest connection.

That means you'll soon be able to play on a phone, tablet or TV, so long as it's on the same 5GHz network as the host PC or it's connected to the computer via Ethernet cable. If you'll recall, the company recently announced that Steam Link will be able beam games to the dedicated iOS and Android apps it's releasing during the week of May 21st. Valve's latest beta client activates the Steam Controller's Bluetooth Low Energy function - a necessary feature if you want to use the gamepad to play on a mobile device in the near future.
