Bluetooth Low Energy Advertising for Piconet Interconnection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for wireless interconnection between smart terminals are inconvenient, requiring users to perform complex settings and connections, which many users are not familiar with, leading to user inconvenience.
Innovation Solution
An interconnection method and system based on Bluetooth low energy and conventional Bluetooth that allows peripheral devices to dynamically advertise service type and address information, enabling a central device to scan and generate a service list, and establish a conventional Bluetooth connection upon request, facilitating easy networking and wireless connection between devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional Bluetooth connection methods are used, then reliable wireless connection can be established, but the connection process is complex and inconvenient for users
Solution Approach 1:
The patent applies preliminary action by having peripheral devices pre-advertise their service information (service type and service address) before connection is needed. The central device scans and collects this information in advance, building a service list that simplifies the actual connection process. This pre-preparation eliminates the need for users to manually configure complex connection parameters, thereby improving ease of operation while maintaining connection reliability.
2Use of energy by moving object
If Bluetooth low energy is used for advertising, then power consumption is reduced, but connection establishment requires additional steps
Solution Approach 1:
The patent segments the Bluetooth communication process into two distinct phases: a discovery phase using Bluetooth low energy for advertising and scanning service information, and a connection phase using conventional Bluetooth for actual data transmission. This segmentation allows the system to use low-power advertising to build a service list, then transition to conventional Bluetooth for connection establishment, thereby reducing standby power consumption while maintaining ease of operation through automated connection based on pre-collected service information.

AI summary
An interconnection method of networking of a Piconet based on Bluetooth low power and conventional Bluetooth is provided. Each of peripheral devices advertise service type information and service address information to the surroundings. The central device generates a peripheral device service list correspondingly according to the serve type information, so as to complete networking between the central device and the plurality of peripheral devices. The central device establishes a conventional Bluetooth connection between the central device and the peripheral device according to a service request, and establishes the Piconet correspondingly to allow any of two devices to be wirelessly connected according to the peripheral device service list.
