System Control Permissions

Why does pressing the voice Fn key do nothing after connecting the Bluetooth Dongle on Mac?

Answer:

1. Make sure the Bluetooth Dongle indicator is on and that it is connected to the app normally.
2. If you are using a Mac mini, make sure voice-input software is installed and the input method is switched to voice input.
3. Go to System Settings → Sound → Input and select AU05 as the input device.
