Bluetooth Mesh Gateway Server Control for Extended Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth mesh networks are limited by constraints on provisioning coverage range, which restricts the range within which a Bluetooth device can be provisioned and added to the network, affecting the development and security of Bluetooth mesh technology.
Innovation Solution
A Bluetooth mesh network comprising a plurality of Bluetooth gateways and a server, where control requests are submitted to the server, which selects a suitable gateway for device control based on signal strength, resources, and compatibility, enabling extended coverage and improved communication range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth devices are added to the Bluetooth mesh network only when located within the signal coverage range of the provisioner, then network security is ensured through proper provisioning, but the provisioning coverage range is limited and affects network development
Solution Approach 1:
The patent introduces a gateway as an intermediary device between the provisioner and Bluetooth devices. The gateway receives provisioning information from the provisioner via wireless communication and forwards it to Bluetooth devices, enabling devices outside the direct provisioner coverage range to be provisioned securely while maintaining network security protocols
Solution Approach 2:
The patent extends provisioning from a single-dimensional direct communication model to a multi-dimensional network model by introducing gateways that can relay provisioning information. This allows provisioning to occur through multiple paths and dimensions, greatly expanding the effective coverage range while maintaining security
2Ease of operation
If a single provisioner is used to maintain simple network management, then ease of operation is improved, but the network coverage and device control capability are limited
Solution Approach 1:
The patent segments the provisioning function by introducing multiple gateways that can independently receive provisioning information from the provisioner and manage local Bluetooth devices. This segmentation expands network coverage while the provisioner maintains centralized control, balancing simplicity with extended capability
Solution Approach 2:
The gateway is designed as a multi-functional device that can both receive provisioning information from the provisioner and communicate with Bluetooth devices. This universal device extends network coverage without requiring multiple provisioners, maintaining operational simplicity while enhancing capability

AI summary
The present application discloses methods, devices, and a system for controlling a Bluetooth device connected to a Bluetooth mesh network. A method includes receiving, by one or more processors associated with a server connected to a Bluetooth mesh network, a control request, wherein the control request is sent to the server by at least one Bluetooth gateway, and the at least one Bluetooth gateway is connected to the Bluetooth mesh network that received the control request sent by a user, and the control request corresponds to a request to control a to-be-controlled Bluetooth device, and controlling, by one or more processors, the to-be-controlled Bluetooth device via at least one Bluetooth gateway among a plurality of Bluetooth gateways connected to the Bluetooth mesh network, the to-be-controlled Bluetooth device being controlled based at least in part on the control request.
