Abstract: For example, a Bluetooth (BT) apparatus may include a System on Chip (SoC), the SoC including an interface to a BT Lower Medium Access Control (MAC) (L-MAC) external to the SoC; and a BT Upper MAC (U-MAC) to generate setup information to configure one or more BT activities by the BT L-MAC, and to send the setup information to the BT L-MAC via the interface, the setup information to configure one or more wakeup criteria for the BT L-MAC to wake up the BT U-MAC, the one or more BT activities including at least a BT scan, wherein the BT U-MAC is configured to enter a power save mode and to wake up from the power save mode based on receipt of a wakeup indication from the BT L-MAC via the interface to the BT L-MAC.

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: For example, an apparatus may be configured to cause a first Bluetooth (BT) mobile device to configure a P2P voice link for voice communication between first and second BT audio devices via a first BT Short-Range (SR) link, a BT Long-Range (LR) link and a second BT SR link, the first BT SR link between the first BT audio device and the first BT mobile device, the BT LR link between the first BT mobile device and a second BT mobile device, and the second BT SR link between the second BT mobile device and the second BT audio device; to communicate a BT SR packet over the first BT SR link, the BT SR packet including a voice payload to be communicated between the first and second BT audio devices; and to communicate a BT LR packet including the voice payload over the BT LR link.

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: For example, a first Bluetooth (BT) device, which may be capable of configuring a BT link for communication between the BT device and a Human Interface Device (HID). For example, the BT device maty include logic and circuitry configured to identify an HID type of the HID. For example, the BT device may configure a slot allocation setting of the BT link between the BT device and the HID, for example, based on the identified HID type of the HID. In one example, the HID type may include a mouse, or a keyboard. In other aspects, any other additional or alternative HID type may be used.

Abstract: For example, a Bluetooth (BT) device may include a first BT radio; a second BT radio; and a BT controller configured to control BT activities of the first and second BT radios, the BT controller configured to process a Host Controller Interface (HCI) command from a host processor of the BT device to setup a BT activity, the BT controller configured to identify one or more scheduling requirements of the BT activity based on the HCI command, and, based on the scheduling requirements of the BT activity, to dynamically schedule the BT activity to a selected BT radio from the first and second BT radios.
