1. A Bluetooth Low Energy (BLE) data transmission method for a smart watch, comprising:
receiving, by a first BLE module of a first micro-controller unit (MCU) of the smart watch, an instruction of transmitting data, wherein the instruction of transmitting data comprises an instruction of transmitting the data to an application processor (AP) of the smart watch or an instruction of transmitting the data to a mobile terminal;
determining, by the first BLE module, whether the AP is in a wake-up state if the instruction of transmitting data is the instruction of transmitting the data to the AP, and transmitting the data to a second BLE module of the AP through a radio frequency communication RFCOMM interface if the AP is determined to be in the wake-up state, otherwise, buffering the to-be-transmitted data; and
synchronizing, by the first BLE module, state information to the second BLE module of the AP if the instruction of transmitting data is the instruction of transmitting the data to the mobile terminal, and transmitting the data to the mobile terminal through the RFCOMM interface.
