Abstract: 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.

Abstract: Methods, apparatus, and computer-readable media are described to encode, by a first station (STA), a polling signal for periodic transmission to a second STA during each air activity instance of a plurality of air activity instances. The first STA detects an interface between a MAC layer and a software stack of a communication protocol is in a low-power state. The communication protocol is associated with a communication link between the first STA and the second STA. An empty packet from the second STA is decoded. The empty packet is received in response to the polling signal transmitted during an air activity instance of the plurality of air activity instances. The periodicity of the periodic transmission of the polling signal is adjusted based on the detected low-power state and the decoded empty packet.

Abstract: Methods, apparatus, systems and articles of manufacture to improve Bluetooth low energy streaming connection efficiency are disclosed herein. An example method includes accessing a request received at a first device from a second device, the request requesting set up of an isochronous link between the first device and the second device, the request including a configuration identifier. Whether the configuration identifier identifies a configuration stored at the first device is determined. In response to determining that the configuration identifier identifies the configuration stored at the first device, the isochronous link using the stored configuration.
