Bluetooth Scanning Filters for Faster Device Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing BLUETOOTH scanning technologies face challenges in efficiently connecting devices due to long scanning times, difficulty in identifying desired devices in environments with interference, and scanning multiple undesired devices, making it difficult to establish connections quickly.
Innovation Solution
A BLUETOOTH scanning control method that sets filter attribute information, such as device types, to filter and display only relevant devices during the scanning process, reducing unnecessary name requests and shortening the scanning time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional BLUETOOTH scanning is performed without filtering, then all BLUETOOTH devices in the environment are scanned, but the scanning time becomes excessively long and many undesired devices are displayed
Solution Approach 1:
The patent applies preliminary action by setting filter attribute information before the BLUETOOTH scanning operation begins. The mobile terminal pre-configures filtering criteria including device types (such as headphones, speakers, microphones) and other attributes that will be used to filter scanned devices. This preliminary setup ensures that only devices matching the specified attributes are displayed, significantly reducing scanning time and eliminating the need to display irrelevant devices while maintaining complete scanning of target device types.
2Productivity
If filtering by device types is implemented, then scanning time is reduced and relevant devices are prioritized, but the complexity of the scanning control increases
Solution Approach 1:
The patent applies parameter changes by introducing filter attribute information as an additional parameter in the BLUETOOTH scanning process. The mobile terminal modifies the scanning behavior by setting specific parameters such as device types (headphones, speakers, microphones, etc.) and other attributes. These parameter changes enable the system to filter devices during scanning, improving efficiency by focusing on relevant device types while managing complexity through structured parameter configuration.
3Loss of information
If name requests are sent to all scanned devices, then device names are obtained for display, but the time consumption increases significantly
Solution Approach 1:
The patent applies the extraction principle by filtering out undesired devices from the scanned device list before sending name requests. The mobile terminal extracts only those devices that match the filter attribute information (specific device types and attributes) and sends name requests solely to these filtered devices. This extraction approach eliminates the need to send name requests to all scanned devices, significantly reducing time consumption while ensuring that device names for relevant devices are still obtained and displayed.

AI summary
The present disclosure relates to a BLUETOOTH scanning control method, a mobile terminal, and a storage medium. The method comprises: after receiving a BLUETOOTH scanning instruction, setting filter attribute information, wherein the filter attribute information is device attribute information of a BLUETOOTH device, which information is to be obtained by means of filtering in the present BLUETOOTH scanning operation; and acquiring the filter attribute information, performing BLUETOOTH scanning according to the filter attribute information, and displaying BLUETOOTH device information obtained by means of scanning. In the present embodiment, during BLUETOOTH scanning, a BLUETOOTH scanning operation is performed according to BLUETOOTH device information corresponding to the set filter attribute information, so as to obtain a BLUETOOTH device obtained by means of filtering and display the BLUETOOTH devices obtained by means of filtering, thereby reducing a scanning period, and achieving the aim of fast scanning.
