For example, a first Bluetooth (BT) device may be configured to operate in a role of a peripheral device over a BT link between the first BT device and a second BT device; and to initiate a role switch to switch the first BT device from the role of the peripheral device to a role of a central device over the BT link between the first BT device and the second BT device, based on a determination that the BT link between the first BT device and the second BT device is to be operated as an audio link to communicate audio data between the first BT device, as an audio source, and the second BT device, as an audio sink.

Apparatus, system and method of bluetooth role switch

For example, a BT audio device may be configured to, during a passphrase-detection mode, monitor an audio input of the BT audio device to detect whether the audio input includes a voice signal, the passphrase-detection mode configured for detection of a predefined user passphrase to indicate a voice command to be provided from a user of the BT audio device; based on a determination that the audio input does not include the voice signal, transmit one or more null-data packets to a BT device over a BT wireless communication link between the BT audio device and the BT device; and, based on a determination that the audio input includes the voice signal, transmit one or more data packets to the BT device over the BT wireless communication link, wherein a payload of the one or more data packets includes audio data based on the audio input.

Apparatus, system and method of communicating audio traffic over a Bluetooth link

An apparatus may be configured to cause an audio source device to transmit an audio stream over a Bluetooth (BT) wireless communication link, the audio stream configured according to a first Advanced Audio Distribution Profile (A2DP) encoding/decoding (codec) scheme; to monitor a link-condition parameter corresponding to a link condition of the BT wireless communication link; and, based on the link-condition parameter, to reconfigure the audio stream according to a second A2DP codec scheme.
