Wireless Device Connection Failure Logging and Diagnosis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack the ability to effectively diagnose and log connection failures between devices, making it difficult to understand the cause of reconnection failures after a connection has been lost.
Innovation Solution
The wireless communication system includes a configuration where devices exchange device information and encryption information during pairing, and upon connection failure, they broadcast connection information including a timestamp, device names, and log data to facilitate diagnosis of reconnection issues, allowing the identification of failure causes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connection failure recovery is implemented by pseudo-resetting output and re-performing authentication processing, then communication connection failures can be recovered from, but the cause of connection failure cannot be elucidated
Solution Approach 1:
The patent applies preliminary action by collecting connection logs before reconnection attempts are made. The system proactively gathers authentication processing details, advertisement packet information, and connection state data during the failure event, so that when recovery is needed, the diagnostic information is already available to elucidate the cause of failure.
Solution Approach 2:
The patent introduces connection logs as an intermediary between the connection failure event and the diagnostic process. These logs serve as a mediator that captures and preserves authentication processing information, advertisement packet data, and connection state details, allowing the cause of failure to be analyzed without interfering with the recovery process.
2Difficulty of detecting and measuring
If connection logs are collected to enable understanding of failure causes, then diagnostic capability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing connection logs that serve multiple functions simultaneously. The same log structure captures authentication processing information, advertisement packet details, and connection state data, allowing a single logging mechanism to support various diagnostic needs without requiring separate specialized systems for each type of information.
Solution Approach 2:
The patent applies parameter changes by collecting specific quantifiable parameters during connection failures, such as authentication attempt counts, packet transmission intervals, signal strength measurements, and timing information. By focusing on measurable parameters rather than qualitative descriptions, the system achieves diagnostic capability through structured data collection.

AI summary
A wireless communication device (100) includes a wireless communicator (134) and a processor (131). The wireless communicator (134) wirelessly communicates with another wireless communication device. The processor (131) controls the wireless communicator (134) to broadcast connection information when reconnection to the other wireless communication device or wireless communication after reconnection with the other wireless communication device fails after termination of a connection with the other wireless communication device. The connection information is information related to the connection.
