Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth technology faces challenges in controlling server operations and managing connections, especially in scenarios where specific operations need to be performed within set times or with security, and there is a lack of clear error messaging for unsupported operations.
Innovation Solution
A method and apparatus that utilize a supported pairing feature procedure to control servers via Bluetooth, allowing clients to request and confirm periodic advertising operations, including security modes, and provide error messages for unsupported operations, leveraging features like periodic advertising mode and synchronization procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth Classic method is used for device connection and control, then compatibility with existing devices is improved, but power consumption increases and connection complexity increases
Solution Approach 1:
The patent divides Bluetooth communication into two distinct methods: Bluetooth Classic (BR/EDR) for high data rate applications and Bluetooth Low Energy (BLE) for low power consumption applications. This segmentation allows devices to select the appropriate protocol based on their specific needs, thereby reducing overall power consumption while maintaining compatibility where required.
Solution Approach 2:
The patent enables dynamic switching between Bluetooth Classic and BLE modes based on operational requirements. Devices can transition between connection types during operation, allowing them to optimize power consumption by using BLE for idle or low-data scenarios while reserving Bluetooth Classic for high-bandwidth tasks, thus making the system adaptable rather than static.
2Adaptability or versatility
If Bluetooth Classic method is used for device connection and control, then compatibility with existing devices is improved, but device complexity increases
Solution Approach 1:
The patent segments the Bluetooth ecosystem into distinct roles (master and slave) with clearly defined functions and procedures for each. This segmentation simplifies the overall system complexity by assigning specific responsibilities to each device type, making it easier to manage connections and reduce complexity despite supporting multiple devices and protocols.
3Ease of operation
If Bluetooth communication is used for server control, then wireless control capability is improved, but connection management complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the master device receives status information from slave devices and can adjust connection management accordingly. This feedback loop enables automated connection handling, reducing the manual intervention required and simplifying connection management while maintaining wireless control capability.
Data Source
AI summary
The present invention relates to a Bluetooth communication method. The Bluetooth communication method may comprise the steps of: performing a supported pairing feature procedure by a client; transmitting, to a first server, a first write request message requesting a writing of a control point attribute for indicating a periodic advertising operation, by the client; receiving, from the first server, a first write response message, in response to the first write request message, by the client; and receiving, from the first server, a first indication message for indicating whether to perform the periodic advertising operation, by the client. In this case, information associated with the periodic advertising operation may include at least one of periodic advertising mode information indicating that a periodic advertising mode is supported and periodic advertising synchronization procedure information indicating that a periodic advertising synchronization establishment procedure is supported.
