Abstract
A method of power-saving and/or proximity-based auto-waking of a mobile device and/or an input device or stylus includes determining, by a mobile device, that motion of an input device has occurred. The method further includes sending, based on the determining of the motion of the input device, a power-on signal to a touch controller circuit and sending a wireless connection beacon using a short-range wireless communication protocol. The method includes receiving acknowledgement data responsive to the wireless connection beacon from the input device and sending, in an instance where a central processing unit (CPU) is in a low-power state, a power-on signal to the CPU. The method further includes receiving, using the short-range wireless communication protocol, input data associated with an interaction of the input device with a display of the mobile device.
