bluetooth update

The first time you turn on the controller, it should enter pairing mode — the status light should flash orange. To enter pairing mode manually, hold the “Y + Stadia” buttons for 2 seconds. Once paired, the controller auto-connects to the last paired device when turned on.

What the status lights mean:

  • Flashing orange / Pairing mode, visible to other devices
  • Flashing white / Connecting to last paired device
  • Solid white / Connected to a device
