Solution Overview
Problem
Users of Bluetooth-enabled Android devices face inconvenience due to the need for manual reconnection after a Bluetooth device is restarted, leading to unnecessary operations and a poor user experience.
Innovation Solution
A method that automatically reestablishes the Bluetooth connection by initializing the connection state, registering Bluetooth monitoring broadcasts, and detecting button events to automate the pairing and connection processes, ensuring seamless reconnection upon device activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile terminal requires manual reconnection when a Bluetooth device reactivates, then the system maintains simple connection management, but the user experience deteriorates due to unnecessary operations
Solution Approach 1:
The system performs preliminary actions by monitoring Bluetooth device activation states and proactively initiating reconnection processes before the user needs to manually connect. The mobile terminal detects when a Bluetooth device reactivates and automatically restarts the connection, eliminating the need for user intervention.
Solution Approach 2:
The connection management system serves itself by automatically detecting Bluetooth device states and initiating reconnection without user input. The mobile terminal's Bluetooth module monitors device activation and autonomously manages the reconnection process, making the system self-sufficient in maintaining connections.
2Extent of automation
If the mobile terminal automatically monitors and reconnects to Bluetooth devices, then the user experience improves by eliminating manual operations, but the system complexity increases due to additional monitoring and automation mechanisms
Solution Approach 1:
The Bluetooth monitoring mechanism serves multiple functions: it detects device activation states, tracks connection status, and initiates reconnection processes. By making the monitoring system multi-functional, the patent avoids adding separate dedicated components for each function, thereby reducing overall system complexity while achieving high automation.
Solution Approach 2:
The system implements feedback loops where the Bluetooth module continuously monitors device activation states and connection status, then uses this information to automatically initiate reconnection when needed. The feedback mechanism enables the system to respond dynamically to device states without requiring complex manual control logic.

AI summary
The present invention provides a method for implementing Bluetooth automatic return link in Android system, which belongs to wireless communication field. The method includes: in a case that the a Bluetooth module is activated, when a mobile terminal detects that Bluetooth broadcast is a Bluetooth connecting request, executing steps of: determining whether a Bluetooth device address contained in the Bluetooth connecting request matches a Bluetooth device address in buffer, if yes, building connection with a current Bluetooth device corresponding to the Bluetooth device address contained in the Bluetooth connecting request, and updating Bluetooth connection state to connected state; otherwise, not responding to the Bluetooth connecting request. By a mechanism of Bluetooth automatic return link provided by the present invention, trouble of manually reconnecting after restarting a Bluetooth peripheral is reduced, which makes operations smarter and simpler and improves easy-using of the product and user experience.
