Bluetooth low energy (BLE) device and method for adjusting operation mode of application processor based on information communicated within BLE packet

摘要

A method of broadcasting a Bluetooth Low Energy (BLE) packet, the method is provided. The method includes generating a random address that includes service identification information of a device, writing the generated random address to a header of the BLE packet, and broadcasting the BLE packet including the header where the generated random address is written, wherein the service identification information of the device includes information to switch an Application Processor (AP) in an external device that receives the BLE packet from a sleep mode to an awake mode.
