Problems solved by technology

If the smart watch includes an MCU system and a smart operating system at the same time, there is no solution to support the Bluetooth transmission of the MCU system when the MCU system and the smart operating system exist in parallel; as a result, the MCU of the smart watch cannot work in the Bluetooth transmission scene. Wake up the application processor (Application Processor, AP) and run the smart operating system, thereby increasing the power consumption of the smart watch

Abstract

An embodiment of the present disclosure provides a Bluetooth low energy BLE data transmission method for a smart watch, including: the first BLE module of the first micro control unit MCU of the smart watch receives an instruction to transmit data; The instruction includes an instruction for transmitting data with the application processor AP or an instruction for transmitting data with the mobile terminal; if the instruction for transmitting data is an instruction for transmitting data with the AP, the first BLE module determines whether the AP is in a wake-up state, If so, transmit data with the second BLE module of the AP through the radio frequency communication RFCOMM interface, otherwise, cache the data to be transmitted; if the instruction for transmitting data is an instruction for transmitting data with a mobile terminal, the first BLE module will The status information is synchronized to the second BLE module of the AP, and data is transmitted with the mobile terminal through the RFCOMM interface.

Description

technical field [0001] The present disclosure relates to the field of smart wearable devices, in particular to a method and device for transmitting Bluetooth Low Energy (Bluetooth Low Energy, BLE) data of a smart watch. Background technique [0002] The usual bluetooth architecture design of smart watches often binds the bluetooth chip with the smart operating system to transmit data through bluetooth. There are also some solutions that realize the Bluetooth transmission of a separate MCU (Micro controller Unit, MCU) system without an intelligent operating system. If the smart watch includes an MCU system and a smart operating system at the same time, there is no solution to support the Bluetooth transmission of the MCU system when the MCU system and the smart operating system exist in parallel; as a result, the MCU of the smart watch cannot work in the Bluetooth transmission scene. Wake up the application processor (Application Processor, AP) and run the smart operating sy...
