Bluetooth Master Device Automatic Slave Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Bluetooth communication networks, users face difficulties in selecting the correct slave device due to non-descriptive and unmodifiable names, leading to inefficient and time-consuming manual selection processes.
Innovation Solution
A method that involves receiving and comparing advertising messages from slave devices, using temporal data such as duration of use counters to automatically select and connect to the appropriate slave device, eliminating the need for users to manually select device names.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of slave devices is used, then user can choose desired device, but selection process becomes time-consuming and inefficient
Solution Approach 1:
The master device automatically selects and connects to the appropriate slave device without requiring user intervention. The system uses temporal data from advertising messages to autonomously determine the correct slave device, eliminating the time-consuming manual selection process while maintaining accurate device identification.
Solution Approach 2:
Slave devices pre-populate their advertising messages with temporal data (such as duration of use counters) before the connection process. This preliminary inclusion of identification data in the advertising phase enables the master device to make automatic selection decisions without requiring additional user input or manual device listing.
2Loss of information
If slave device names are used for identification, then user can recognize devices, but names are non-descriptive and cannot be modified
Solution Approach 1:
The system changes the identification parameter from static factory-burned names to dynamic temporal data (duration of use counters) that can vary and be modified. These temporal parameters are included in advertising messages and can be updated by the slave devices, providing both accurate identification and adaptability without requiring name changes.
Solution Approach 2:
The patent introduces temporal data as an intermediary element between the slave device and the master device for identification purposes. Instead of relying on fixed names, the system uses time-based counters and duration data as a mediator that conveys device identity and status dynamically, allowing for both accurate recognition and future modifications.

AI summary
A method for connecting a master device with a slave device chosen from among several slave devices. The method includes: receiving advertising messages arising from several slave devices, the messages including respective selection data; comparing the selection data received; and connecting with at least one slave device as a function of a result of the comparing.
