Unfortunately, the 'Noise' BLE smartwatch likely doesn't support sending keyboard commands like a BLE keyboard would. It's designed for specific functions like notifications and fitness tracking. You might need a different device or approach to achieve volume control via BLE. Keep exploring options, and you'll find a solution that fits your needs!
