Bluetooth Hearing Aid Pairing When Device Type Data Is Missing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face difficulties in connecting to Bluetooth hearing aids due to the inability to accurately recognize the device type when critical information is missing from notification packets, leading to cumbersome connection processes and potential failures.
Innovation Solution
The method involves determining the device type of a Bluetooth hearing aid based on additional information from scan response frames or device names, left/right identifiers, and historical connection data, enabling direct or guided connection even when primary identification information is absent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device relies on notification packets for device type recognition, then the connection process is simple, but the recognition accuracy deteriorates when notification packets are missing critical information
Solution Approach 1:
The electronic device performs preliminary actions by checking multiple information sources (notification packets, scan response frames, service lists) in a predetermined sequence before initiating connection. This ensures that device type recognition is completed accurately even when some information fields are missing, resolving the contradiction between recognition accuracy and connection simplicity.
Solution Approach 2:
The patent introduces intermediary information sources (scan response frames, service lists) that mediate between the primary notification packet and the final device type determination. When the notification packet is insufficient, these intermediary sources provide the necessary additional information to achieve accurate recognition without complicating the overall connection process.
2Reliability
If the electronic device checks multiple information sources for device type determination, then the recognition reliability improves, but the time required for connection increases
Solution Approach 1:
The electronic device performs preliminary checks of available information sources in a predetermined sequence, stopping once sufficient information is found. This approach ensures reliable device type recognition while minimizing time consumption by avoiding unnecessary checks of all possible information sources.
Solution Approach 2:
The patent applies partial action by checking only the necessary portion of available information (notification packet first, then scan response frame, then service list) rather than exhaustively checking all possible sources. This achieves sufficient reliability for accurate device type recognition without the time penalty of complete exhaustive checking.
3Reliability
If the electronic device uses default connection procedures, then the operation simplicity is maintained, but the connection success rate deteriorates when notification packets are incomplete
Solution Approach 1:
The electronic device performs self-service by automatically detecting the presence and completeness of notification packets and autonomously selecting appropriate information sources for device type determination. This eliminates the need for user intervention while ensuring successful connection even when notification packets are incomplete, maintaining both simplicity and reliability.
Solution Approach 2:
The device performs preliminary assessment of notification packet completeness and automatically initiates appropriate follow-up actions (checking scan response frames, service lists) without user input. This self-service approach ensures high connection success rates while preserving ease of operation, as the user simply needs to initiate the connection process without managing underlying complexity.

AI summary
This application provides a method for connecting a Bluetooth hearing aid, an electronic device, and an apparatus. The method includes: after receiving a BLE broadcast packet sent by a peripheral device, if a notification packet does not include first information and second information, determining a device type of the peripheral device based on third information in a scan response frame or fourth information, where the first information and the second information are respectively configured to indicate the device type and a left-ear identifier or a right-ear identifier, the third information is at least one piece of information indicating the device type and information indicating the left-ear identifier or the right-ear identifier, and the fourth information is located in the notification packet and/or the scan response frame and configured to indicate a service supported by the peripheral device; and if the device type of the peripheral device is a Bluetooth hearing aid, connecting the Bluetooth hearing aid. This resolves, in the conventional technologies, a problem that an electronic device is difficult to be connected to the Bluetooth hearing aid because the electronic device cannot recognize a device type of the Bluetooth hearing aid.
