Bluetooth Master Slave Power Balance via Dynamic Responder Role
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth wireless devices experience unbalanced power consumption between master and slave devices due to high power usage by the master device, leading to inefficiencies and communication disruptions during role switching, which requires a long time and results in pauses and disconnections.
Innovation Solution
The communication method involves alternately designating the master and slave devices as responders at intervals or based on data reception success, with one device serving as an authority manager to manage response authority, ensuring balanced power consumption without affecting terminal communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the master device continuously serves as the responder to maintain communication with the terminal, then communication reliability is improved, but power consumption of the master device increases and becomes unbalanced compared to the slave device
Solution Approach 1:
The patent implements dynamic role switching where the master and slave devices can exchange responder and non-responder roles based on communication needs. This dynamic adjustment allows the system to maintain communication reliability while balancing power consumption, as either device can take turns serving as the responder rather than the master device bearing the continuous burden alone.
2Use of energy by moving object
If the master and slave devices switch roles to balance power consumption, then power consumption balance is improved, but communication interruptions occur during the switching process
Solution Approach 1:
The patent employs preliminary actions during role switching by having the prospective responder prepare in advance and establish connectivity before the actual switch occurs. The switching process includes preliminary steps where the device about to become the responder first connects to the terminal, ensuring that communication continuity is maintained throughout the transition without pauses or disconnections.
3Use of energy by moving object
If role switching is implemented to balance power consumption, then power consumption balance is improved, but switching time increases causing communication pauses
Solution Approach 1:
The patent ensures continuity of useful action during role switching by maintaining active communication channels throughout the transition. The switching mechanism is designed so that one device continues serving as the responder while the other transitions, eliminating gaps in communication and reducing switching time to minimal or zero perceived pause for the end user.

AI summary
A communication method for a wireless device, a wireless device and a computer readable storage medium are provided to reduce power consumption of a master device in the wireless device and balance power consumptions of the master device and a slave device. The communication method for a wireless device according to the embodiments of the present disclosure includes: alternately serving, by the master device and the slave device of the wireless device, as a responder, and sending, by the responder, a response message to the terminal via the first Bluetooth link. The response message indicates a result of receiving the Bluetooth data by the wireless device.
