Abstract
The disclosed systems and method provide for an audio playback device to form a Bluetooth connection with an audio source device based on audio generated by an acoustic transducer. The audio is encoded with Bluetooth connectivity data corresponding to the audio source device. The acoustic transducer can be arranged on the audio source device, or it can be arranged on an audio playback device connected to the audio source device via a Bluetooth connection. The audio is received by a microphone of an audio playback device. The audio playback device then extracts the Bluetooth connectivity information from the audio, and forms a Bluetooth connection with the audio source device. If the Bluetooth connection is a Broadcast Audio stream, as defined by the LE Audio standard, multiple audio playback devices can be able to connect audio source device, allowing for a communal listening experience.
