Problems solved by technology

[0002] At present, smart wearable devices (such as bracelets or watches) on the market are usually limited in size, and the built-in lithium battery capacity is generally very small, but in the actual application process, smart wearable devices have higher requirements for battery life.
As the only way for smart wearable devices to communicate with mobile phones, the Bluetooth module must maintain a long-term high-speed mode of operation during actual use to ensure real-time upload of various data, which causes a lot of power consumption
When Bluetooth is in communication, although it can change the speed between 200B / s and 3KB / s, once the amount of transmitted data is large and Bluetooth is in low-speed mode, it will take a long time to transmit data and cause serious delays. user experience

Embodiment 1

[0093] Please refer to figure 1 , a method for reducing bluetooth communication power consumption, comprising steps:

[0094] S01. Pre-configure and save the communication rate of the Bluetooth module of the wearable device in each application scenario and the correspondence between the communication rate of the Bluetooth module and each application scenario;

[0095] S1. Set the Bluetooth module of the wearable device to enter the low frequency mode;

[0096] S2. Judging whether a rate switching signal for the current application scene of the wearable device is received, if so, perform step S3, otherwise, set the Bluetooth module of the wearable device to maintain a low frequency mode;

[0097] S3. Switch the Bluetooth module of the wearable device from low frequency mode to high frequency mode, including:

[0098] According to the current application scene of the wearable device indicated by the rate switching signal, the rate switching signal directly indicates the curren...

Embodiment 2

[0104] Please refer to figure 1 and image 3 The difference between this embodiment and Embodiment 1 is that, after the step S3, it also includes:

[0105] Receive an interrupt signal, and set the Bluetooth module of the wearable device to re-enter the low frequency mode according to the interrupt signal;

[0106] The interrupt signal instructs the wearable device to end the current application scenario.

[0107] Applying the above scheme to a specific application scenario, the wearable device is a bluetooth bracelet, and the communication rate of the bluetooth module on the bluetooth bracelet is between 200byte / s and 3kb / s, and the bluetooth module is The default state of the Bluetooth bracelet is in the low frequency mode of 200byte / s when it is in standby, so as to ensure the low power consumption of the Bluetooth bracelet. Or the rate switching signal of the scene corresponding to the swiping card transaction, the Bluetooth bracelet receives the said rate switching sign...

Embodiment 3

[0109] Please refer to figure 1 The difference between this embodiment and Embodiment 1 is that it further includes: receiving a request for reducing the application scenarios of the wearable device, where the request indicates the reduced application scenarios;

[0110] According to the reduced application scenario indicated by the request, delete the communication rate of the corresponding Bluetooth module and the corresponding relationship between the communication rate and the corresponding application scenario;

[0111] At the same time, it also includes: receiving a request to increase the application scenario of the wearable device, the request indicating the increased application scenario and the communication rate of the corresponding Bluetooth module;

[0112] According to the increased application scenario indicated by the request and the communication rate of the corresponding Bluetooth module, increase and store the communication rate of the corresponding Bluetoot...

Abstract

The invention provides a method and terminal for reducing the power consumption of bluetooth communication. The method comprises the steps of setting a bluetooth mode of wearable equipment to enter alow frequency mode; judging whether a rate switching signal for the current application scenario of the wearable equipment is received or not; if not, setting the bluetooth mode of the wearable equipment to maintain the low frequency mode; otherwise, switching bluetooth module of the wearable equipment from the low frequency mode to a high frequency mode, wherein the communication rate of the bluetooth module of the wearable equipment under the high frequency mode is greater than the communication rate of the bluetooth module of the wearable equipment under the low frequency mode. The bluetooth module enters the high frequency mode when the amount of transmitted data is great so as to improve the data transmission efficiency, and the bluetooth module maintains the low frequency mode in idle or when the amount of data is small, so that the communication rate of the bluetooth module is automatically adjusted according to changes of the current application scenario, and the power consumption of bluetooth communication is reduced.
