Some advanced Bluetooth information is protected by Android. A one-time setup using Wireless Debugging may therefore be required to grant the app access to the system Bluetooth report. A computer is not required, and Wireless Debugging can be disabled after setup.
Available parameters and control options depend on the Android version, device manufacturer, firmware, and connected Bluetooth audio device. The phone or headphones may automatically select the nearest compatible mode.
Bluetooth information and monitoring history are processed locally on your device. The app does not upload Bluetooth reports to the developer’s servers.
