Bluetooth Device Search Sorting and Connection Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios with multiple Bluetooth devices present, existing methods are inefficient for discovering a desired device and often result in unnecessary connections with undesired devices, leading to prolonged inquiry procedures and interference.
Innovation Solution
A method and apparatus that sorts responding Bluetooth devices based on a preset service list and connection blocking list, allowing for efficient device name retrieval and blocking unwanted connections, thereby reducing search time and preventing unwanted connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the inquiring Bluetooth device lists all responding Bluetooth devices on the display screen, then the user can readily select a desired device when few devices are present, but the inquiry procedure spends a long time when many Bluetooth devices are present
Solution Approach 1:
The patent segments the inquiry procedure into two phases: a rapid scanning phase that quickly identifies responding devices and their services, and a selective detailed inquiry phase that only requests device names from devices matching the preset service list. This segmentation reduces the overall inquiry time while maintaining ease of device selection for relevant devices.
Solution Approach 2:
The patent performs preliminary filtering of responding devices based on their advertised services against a preset service list before initiating the device name request. This preliminary action eliminates the need to retrieve names from all responding devices, thereby reducing inquiry procedure time while ensuring that only relevant devices are displayed for user selection.
2Device complexity
If the inquiry list is limited in number of Bluetooth devices, then the display is manageable, but a desired Bluetooth device may not be present in the inquiry list
Solution Approach 1:
The patent applies local quality by differentiating the treatment of devices in the inquiry list based on their service characteristics. Devices that match the preset service list receive full attention (name requests and display), while non-matching devices are quickly filtered out. This ensures that the limited display space is dedicated to devices of interest, preventing information loss for desired devices while maintaining manageable list complexity.
3Productivity
If a Bluetooth device repeatedly tries to connect to another device, then connection attempts are made, but interference occurs preventing efficient Bluetooth communication
Solution Approach 1:
The patent implements preliminary anti-action by introducing a connection blocking list that pre-prevents connection attempts from undesired devices. Before allowing any connection procedure to occur, the system checks whether the requesting device is on the blocking list and intercepts the connection attempt if it is. This preliminary blocking action eliminates connection interference from unwanted devices while allowing legitimate connection attempts to proceed.

AI summary
A Bluetooth master device is capable of performing search and connection method for Bluetooth devices. The Bluetooth master device receives device information from at least one Bluetooth device in response to a Bluetooth device search request made by a user. A responding Bluetooth device that is capable of providing a Bluetooth service in a preset service list is selected. The Bluetooth master device sends a name request signal to the selected Bluetooth device and displays a device name received from the selected Bluetooth device.
