Google is about to discontinue its Bluetooth conversion utility for the Stadia Controller. Act quickly to switch your controller to Bluetooth mode while the official tool is still available.
After shutting down the Stadia streaming service in January 2023, Google released a tool to enable Bluetooth connectivity on Stadia Controllers, effectively repurposing them as standard wireless controllers. The initial deadline for this tool was the end of 2023, but Google extended it to December 31, 2024.
While some third-party tools exist on GitHub, their long-term viability is uncertain. It's recommended to update your Stadia Controller using the official Google tool while you still can.
