Abstract: Apparatuses, systems, and methods broadcast a device state in a wireless communication network. A wireless audio output device is configured to be paired with a second wireless device via a first piconet connection, wherein the second wireless device comprises a source of audio data to be output by the wireless audio output device. The wireless audio output device includes a processor configured to detect a change in the state of the wireless audio output device and set a transmission parameter of a broadcast transmission based at least in part on the detected change in the state and a transceiver configured to broadcast an advertising message to the second wireless device including information describing the wireless audio output device via the broadcast transmission.
