Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth technologies, such as single-mode modules, lack compatibility between Bluetooth Low Energy (BLE) and Basic Rate/Enhanced Data Rate (BR/EDR) protocols, limiting their ability to efficiently switch between modes and maintain data transmission efficiency.
Innovation Solution
A dual-mode Bluetooth module that integrates both BLE and BR/EDR protocols, allowing for seamless switching between modes by monitoring interrupt request signals to manage data transmission effectively, ensuring continuous operation and efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-mode Bluetooth communication module is used, then the device complexity is reduced, but the adaptability and compatibility between BLE and BR/EDR protocols deteriorates
Solution Approach 1:
The patent implements a dual-mode Bluetooth communication module that integrates both BLE and BR/EDR protocols into a single device. The controller is configured to support multiple Bluetooth working modes, allowing the module to universally communicate with different types of Bluetooth devices regardless of their specific protocol version, thereby resolving the contradiction between simplicity and versatility.
2Adaptability or versatility
If switchover is implemented between BLE and BR/EDR modes in a dual-mode module, then the adaptability is improved, but the data transmission efficiency and reliability deteriorate due to mode switching disruptions
Solution Approach 1:
The patent introduces a preliminary action mechanism where the controller monitors whether the first Bluetooth working mode (BR/EDR) needs to be switched to the second working mode (BLE) before actual data transmission disruption occurs. By detecting the need for mode switching in advance and preparing the appropriate working mode ahead of time, the system minimizes transmission interruptions and maintains reliability during mode transitions.
3Adaptability or versatility
If mode switching is frequently implemented to adapt to different communication needs, then the adaptability is improved, but the loss of time and switching overhead increases
Solution Approach 1:
The patent implements a feedback mechanism where the controller continuously monitors the operational state of the first Bluetooth working mode and detects whether switching to the second working mode is necessary. Based on this real-time feedback, the system makes intelligent decisions about when to switch modes, avoiding unnecessary switching operations and reducing time loss while still maintaining high adaptability to changing communication needs.
Data Source
AI summary
A method for switching Bluetooth working modes, an electronic device, and a Bluetooth chip are disclosed. The method includes: executing a first Bluetooth working mode, the first Bluetooth working mode including a working state in which data is normally transmitted and an error state in which data fails to be transmitted; monitoring a first interrupt request signal sent in a second Bluetooth working mode if the first Bluetooth working mode works in the working state; and executing the second Bluetooth working mode and enabling the first Bluetooth working mode to work in the error state if the first interrupt request signal is present.
