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.
