Bluetooth Cluster Online Upgrade via Central Node Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth cluster upgrade technologies face low success rates and prolonged upgrade times due to data congestion and inefficient data transmission in large-scale, multi-layer clusters, where each device must obtain upgrade data directly from an upgrade device.
Innovation Solution
An online upgrade method and apparatus that selects a central node in the Bluetooth cluster to establish a connection and transmit upgrade data, using a selected upgrade path to distribute upgrade data efficiently among devices, reducing the need for direct device-to-device data transmission and minimizing the number of devices through which data passes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If each Bluetooth device obtains upgrade data directly from the upgrade device, then the upgrade process is simple to implement, but data congestion occurs and upgrade success rate decreases
Solution Approach 1:
The patent introduces intermediary nodes (central node and relay nodes) in the Bluetooth cluster to forward upgrade data. Instead of each device directly receiving data from the upgrade device, data flows through selected intermediary devices that relay it to multiple target devices, thereby distributing data transmission load and preventing congestion while maintaining upgrade simplicity
Solution Approach 2:
The patent segments the upgrade data transmission process into multiple paths through different nodes in the Bluetooth cluster. By dividing the single direct transmission path into multiple segmented paths through central and relay nodes, the system distributes the data transmission load, preventing congestion and improving reliability
2Ease of manufacture
If each Bluetooth device obtains upgrade data directly from the upgrade device, then the upgrade protocol is straightforward, but upgrade time-consumption increases significantly
Solution Approach 1:
The upgrade data transmission is segmented into parallel paths through central nodes and relay nodes. This segmentation enables simultaneous data transmission to multiple devices, reducing the total time required compared to sequential direct transmission from the upgrade device to each individual device
Solution Approach 2:
Intermediary nodes enable efficient data distribution by receiving upgrade data once and forwarding it to multiple target devices. This mediator approach reduces the total transmission time compared to the upgrade device communicating directly with each device individually
3Productivity
If multiple Bluetooth devices are upgraded simultaneously, then upgrade efficiency improves, but data transmission complexity and difficulty increase
Solution Approach 1:
The patent uses central nodes and relay nodes as intermediaries to manage simultaneous data transmission to multiple devices. These intermediaries handle the complexity of coordinating multiple transmission paths, allowing efficient parallel upgrades while keeping the overall system manageable through hierarchical organization
Solution Approach 2:
The system segments the Bluetooth cluster into hierarchical groups managed by central and relay nodes. This segmentation allows simultaneous upgrades in different segments to proceed independently, improving overall efficiency while reducing transmission complexity within each segment
4Area of stationary object
If upgrade data is transmitted through many Bluetooth devices, then coverage is extended, but the number of devices involved in transmission increases and success rate decreases
Solution Approach 1:
The patent strategically selects specific intermediary nodes (central node with strongest receiving power, and relay nodes with most connected devices) to forward upgrade data. This selective intermediary approach extends coverage through the Bluetooth cluster while minimizing the number of devices involved in transmission, thereby maintaining higher success rates

AI summary
The present disclosure relates to the field of Internet of Things, and in particular, to an online upgrade method and apparatus for a Bluetooth cluster. The online upgrade method for the Bluetooth cluster includes: an upgrade device selects a central node in the Bluetooth cluster and establishes a Bluetooth connection with the central node; the upgrade device selects an upgrade path, and sends upgrade data to a to-be-upgraded device through the central node according to the upgrade path, enabling the to-be-upgraded device to obtain the upgrade data to achieve an upgrade, where the to-be-upgraded device includes a part or all of Bluetooth devices in the Bluetooth cluster. The online upgrade method of the Bluetooth cluster adopted in the present disclosure further broadens a communication range of the Bluetooth, which requires no one-to-one operation by a user.
