Bluetooth Low Energy to Classic Mode Handover for iOS Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
iOS devices face limitations in controlling Bluetooth classic mode connections and disconnections through applications, making it difficult to transmit and receive data of a predetermined capacity or over due to security design restrictions, while BLE connections are slow and inconvenient for such data transfers.
Innovation Solution
A method that involves transmitting a MAC address from a terminal to a data device in BLE mode, disconnecting the BLE connection, and establishing a classic Bluetooth connection without acknowledgment, allowing the iOS application to control the data device's classic Bluetooth connection, enabling efficient data transmission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If BLE connection is used for data transmission, then connection control accessibility is improved, but communication speed deteriorates
Solution Approach 1:
The patent segments the Bluetooth connection process into two distinct phases: first establishing a BLE connection for authentication and parameter exchange, then transitioning to BT classic mode for high-speed data transmission. This segmentation allows each mode to perform its specialized function optimally without compromising the other.
Solution Approach 2:
The system dynamically switches between BLE and BT classic modes based on the operational requirements. The connection mode is not fixed but adapts according to whether authentication or high-speed data transmission is needed, providing flexibility in the communication protocol selection.
2Speed
If BT classic mode connection is used for data transmission, then communication speed is improved, but connection control accessibility deteriorates
Solution Approach 1:
The patent introduces BLE connection as an intermediary mechanism that enables application-level control over the subsequent BT classic mode connection. The BLE connection serves as a mediator that authenticates the application and exchanges control parameters, allowing the application to influence the BT classic connection establishment despite iOS security restrictions.
Solution Approach 2:
The system performs preliminary authentication and parameter exchange through BLE connection before establishing the BT classic mode connection. This preliminary action in BLE mode sets up the necessary conditions and control parameters that enable application-level influence over the subsequent high-speed data transmission connection.
3Device complexity
If single mode BLE chip is used, then device simplicity is improved, but bidirectional communication capability deteriorates
Solution Approach 1:
The patent implements a dual-mode Bluetooth chip that can operate in both BLE and BT classic modes, providing multi-functionality. The same hardware platform can adapt to different communication requirements by switching between energy-efficient BLE mode for authentication and high-speed BT classic mode for data transmission, eliminating the need for separate devices.
Data Source
AI summary
A method for performing communication with a data device by a terminal supporting Bluetooth connection of a first profile and a second profile is provided, which includes transmitting a media access control (MAC) address of the terminal to the data device having established a first connection in the first profile with the terminal; disconnecting the first connection; receiving, from the data device, a request for a second connection in the second profile through the MAC address of the terminal; identifying the data device using pre-registered first information; and establishing the second connection without transmission of an acknowledgment for the second connection.
