Offline Smart Device Network Recovery via Bluetooth Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart devices with Wi-Fi functions experience prolonged offline states due to failed automatic reconnection attempts, requiring manual re-access to the network, which is inconvenient for users.
Innovation Solution
A method that determines if a device is offline by automatic reconnection failure, then uses connected second devices to establish a communication connection via Bluetooth, allowing data transmission through these devices to re-access the network, enabling convenient user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic reconnection mechanism is used for Wi-Fi devices, then reconnection can be attempted automatically, but the device remains offline for extended periods when reconnection fails multiple times
Solution Approach 1:
The patent introduces a second device as an intermediary relay node between the offline first device and the router. When automatic reconnection fails, the first device establishes a connection through the second device, which forwards data packets, enabling the offline device to re-access the network without manual intervention and reducing offline duration
2Reliability
If manual re-access is required when automatic reconnection fails, then device control can be recovered, but user convenience is reduced
Solution Approach 1:
The system implements self-service by automatically selecting a second device from the local area network and establishing a relay connection without user intervention. The first device autonomously recovers network access through the second device, maintaining device control reliability while preserving user convenience
3Adaptability or versatility
If Bluetooth module is used for device discovery and connection, then offline devices can be found and connected, but additional hardware components are required
Solution Approach 1:
The patent applies universality by utilizing the Bluetooth module's dual functionality: it serves both as a device discovery mechanism for finding second devices in the local area network and as a communication channel for establishing the relay connection. This multi-functional approach enables offline device recovery without adding separate hardware components

AI summary
The disclosure relates to the technical field of communications, and in particular, to a method for establishing a communication connection after a device is offline and a smart home system. The method for establishing the communication connection after the device is offline comprises: whether a first device is in an offline state in a Wi-Fi network under a wireless router is determined; when the first device is in the offline state, the first device is connected to at least one second device in Wi-Fi connection with the wireless router; and the first device establishes a communication connection with the wireless router by means of the second device. According to the method provided by the disclosure, an offline terminal can establish a communication connection with the wireless router by means of other terminals under the wireless router.
