Firmware is updated through the 8BitDo Ultimate Software (V2) on Windows or macOS over USB-C; it detects the controller and prompts when a newer firmware is available. Note (2025): 8BitDo confirmed the Ultimate Bluetooth Controller needs a firmware update via Ultimate Software before it works on Nintendo Switch 2, so update first if you plan to use it there. Do not disconnect during the update.
