US Patent 11435810 Information handling system and peripheral bi-directional wakeup interface

An information handling system wirelessly interfaces with a peripheral device, such as a keyboard or mouse, through a primary radio and communication protocol, such as Bluetooth. A secondary radio interfaces with the primary radio to provide a low power wake and sleep using a wake signal sent between the secondary radios. An information handling system may wake the peripheral, such as at system power up, or the peripheral may wake the information handling system, such as at detection of an input at the peripheral for communication to the information handling system.
