Abstract: Some demonstrative embodiments include devices, systems and/or methods of Bluetooth communication. For example, a Bluetooth communication unit may be capable of detecting a Bluetooth signal via a first antenna, and, upon detecting the Bluetooth signal, to switch to a second antenna, which is shared between the Bluetooth communication unit and an other, different, wireless communication unit, for establishing a Bluetooth communication link.

Abstract: Some embodiments herein include at least one of systems, methods, and devices for power-efficient data transfer between two communicating devices. The two devices establish two wireless links between each other; the first link using a low-power/low-throughput protocol and utilized to maintain a second link, the second link using a high-power/high-throughput protocol. When first device data is available for transmission, the first device instructs the second device via the first link to switch to the second link for data reception. The first device then transmits data to the second device via the second link. When the transmission is complete, both devices switch back to using the first link to maintain their connection to each other. In some embodiments, the first device may be a Human Interface device and the second device may be a Bluetooth controller of a computing device.

Abstract: Disclosed in some examples is a method including receiving a downlink data packet over a first wireless link using a first wireless protocol during communications over a second wireless link using a second wireless protocol the first and second wireless protocols being different; and sending a control packet in response to the downlink data packet over the first wireless link using a reduced power setting during the communications over the second wireless link, the reduced power setting being less than a non-control packet power setting.
