Debug Connection Control via Dual USB Wi-Fi Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining a stable connection between a debug tool and a device during debugging operations is challenging due to potential disconnections, which can interrupt debugging sessions, especially when using USB connections, and restarting the session is often necessary upon loss of connection.
Innovation Solution
Implementing a high availability connection control module on both the debug tool and device sides to establish and manage dual socket connections via USB and Wi-Fi, allowing seamless switching between primary and backup channels to ensure continuous debugging sessions without interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single USB connection is used for debugging, then the connection is simple to establish, but the connection stability deteriorates due to potential disconnections
Solution Approach 1:
The patent combines two different communication channels (USB and Wi-Fi) into a unified debugging connection system. The debug tool and device can establish connections through either USB or Wi-Fi, merging the advantages of both channels to achieve both ease of operation and connection stability.
Solution Approach 2:
The system dynamically switches between USB and Wi-Fi connections based on real-time connection status. When the primary USB connection is lost, the system automatically transitions to the Wi-Fi backup connection, and vice versa, making the connection pathway adaptive and dynamic rather than static.
2Reliability
If dual socket connections via USB and Wi-Fi are implemented, then connection reliability is improved through backup channels, but device complexity increases
Solution Approach 1:
The connection management system operates autonomously without requiring user intervention. The high availability connection control module automatically monitors connection status, detects disconnections, and switches between USB and Wi-Fi channels without user input, making the complexity invisible to the end user.
Solution Approach 2:
The system continuously monitors the status of both USB and Wi-Fi connections and uses this feedback to make real-time switching decisions. The connection control module receives status information from both channels and automatically adjusts the active connection based on current conditions, creating a closed-loop control system.
3Duration of action of stationary object
If automatic connection switching is implemented, then debugging session continuity is maintained, but the control mechanism becomes more complex
Solution Approach 1:
The system establishes both USB and Wi-Fi connections in advance before debugging begins. The backup Wi-Fi connection is pre-configured and ready to use, so when a disconnection occurs, the switch can happen immediately without delay or requiring reconnection setup, thus maintaining session continuity.

AI summary
In some examples, device debugging connection control and maintenance may include receiving, from a debug tool, a connection request to connect to a device to be debugged. Based on the connection request, a primary socket connection may be implemented via a Universal Serial Bus (USB) channel to the device. Based on the connection request, a backup socket connection may be implemented via a Wi-Fi channel to the device. Based on the implementation of the primary socket connection and the backup socket connection, maintenance of a debugging session may be controlled during performance of a debugging operation.
