Bluetooth Audio Pairing via Alternating Fast Pair Broadcasts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Bluetooth connection methods between audio devices and terminal devices suffer from low efficiency and compatibility issues due to the lack of support for multiple pairing manners, leading to unsuccessful connections for devices that do not support the specific pairing method broadcast by the audio device.
Innovation Solution
The audio device broadcasts first and second connection configuration information corresponding to different pairing manners alternately, allowing it to establish Bluetooth connections with terminal devices supporting either the self-defined fast pair manner or the Google fast pair manner, respectively, without requiring the terminal device to send connection requests through its Bluetooth configuration interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the audio device broadcasts only one type of connection configuration information, then the connection process is simple, but terminal devices supporting other pairing manners cannot establish connections
Solution Approach 1:
The audio device broadcasts different connection configuration information (first connection configuration information for first pairing manner and second connection configuration information for second pairing manner) periodically in an alternating manner. This periodic switching allows the audio device to support multiple pairing manners without requiring terminal devices to handle multiple simultaneous broadcast types, thus improving compatibility while maintaining broadcast simplicity.
2Productivity
If the terminal device sends connection requests through Bluetooth configuration interface, then the connection process is standardized, but the connection efficiency is reduced
Solution Approach 1:
The audio device pre-broadcasts the connection configuration information (including pairing manner-specific parameters) before the terminal device needs to establish a connection. This preliminary action allows the terminal device to directly use the broadcasted information for connection without needing to send standardized connection requests through the Bluetooth configuration interface, thereby improving connection efficiency and reducing manual configuration steps.
