Dual-Mode Bluetooth Connection Accuracy via Sequential Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual-mode Bluetooth devices often experience misconnection issues when attempting to establish both classic Bluetooth and Bluetooth Low Energy connections simultaneously, as they may inadvertently connect to other devices instead of the intended dual-mode device.
Innovation Solution
A method and device configuration that involves a terminal device searching for and establishing a connection with a dual-mode Bluetooth device in one mode, obtaining identification information, and then establishing a connection in the alternate mode to ensure accurate pairing and avoid misconnections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a terminal device enables Bluetooth mode to connect with a dual-mode Bluetooth device, then connection establishment is simplified, but misconnection occurs because the terminal may connect to other Bluetooth devices instead of the intended dual-mode device
Solution Approach 1:
The patent applies preliminary action by having the terminal device first establish a connection in a first Bluetooth mode (classic or Low Energy), obtain the identification information of the dual-mode Bluetooth device, and then use this identification information to establish the second Bluetooth mode connection. This sequential approach with intermediate identification exchange prevents the terminal from mistakenly connecting to other devices while maintaining ease of operation.
2Speed
If the terminal device searches for and connects to dual-mode Bluetooth devices without using identification information, then connection speed is improved, but the terminal may establish connections with incorrect devices
Solution Approach 1:
The patent implements feedback by having the terminal device obtain identification information from the dual-mode Bluetooth device after the first connection is established, and then use this feedback information to verify and ensure accurate device identification before establishing the second mode connection. This feedback mechanism maintains speed while ensuring precision.
