Method and device for reducing power consumption

摘要

A method for reducing power consumption between two devices communicating through a BLUETOOTH protocol is operable to be executed in the devices. A first device can adjust connection state according to current communication state with a second device, to achieve a compromise between power saving and effective transmission abilities.

1. A method for reducing power consumption, performed by a first device, the first device adapted to communicate with a second device using a Bluetooth low energy protocol, the method comprising:
pre-setting a plurality of power modes for the first device and pre-setting a plurality of connection parameters for the second device, wherein one of the plurality of connection parameters corresponds to one of the plurality of power modes; determining a communication state between the first device and the second device; selecting a first one of the plurality of power modes based on the communication state; notifying the second device of the first power mode to enable the second device to configure a first one of the plurality of connection parameters corresponding to the first one power mode; receiving a first feedback from the second device; and adjusting a connection state between the first device and the second device according to the first feedback.
