This is an Android-only permission for Android 12 or later.
It lets the Visualfy app access the Bluetooth connection, so you can connect wireless headphones or microphones and use them with Visualfy Connect. This way, the audio is picked up by the wireless device instead of the phone’s own microphone.
To enable this permission, follow the steps shown in the video. If you tapped “Deny/Don’t allow”, you can enable the permission as shown in the video below.
