Abstract: Embodiments of the present disclosure provide a data transmission method, apparatuses, and a smart watch device. A first BLE module of a first MCU of a smart watch receives an instruction of transmitting data which includes an instruction of transmitting the data to an AP of the smart watch or a mobile terminal. The first BLE module determines whether the AP is in a wake-up state if the instruction is to transmit the data to the AP, and transmits the data to a second BLE module of the AP through a RFCOMM interface if the AP is determined to be in the wake-up state, otherwise, buffers the to-be-transmitted data. The first BLE module synchronizes state information to the second BLE module if the instruction is to transmit the data to the mobile terminal, and transmits the data to the mobile terminal through the RFCOMM interface.

Abstract: A data processing method, apparatus and system, and a computer-readable storage medium are disclosed, wherein the method is applied to a first electronic device, the first electronic device includes a first processing unit that runs a first operating system and a second processing unit that runs a second operating system, and the working energy consumption of the first processing unit is less than the working energy consumption of the second processing unit. The method includes: the first processing unit executing the selection of a positioning system, and storing selected positioning system information; when it is determined that a first trigger condition for executing the synchronization of the positioning system information is met, synchronizing the stored positioning system information to the second processing unit; and the second processing unit executing positioning-related processing according to the obtained positioning system information.
