BLE Intermediary for Seamless Source Device Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless devices, such as wearable audio devices, face challenges in efficiently switching between source devices due to limited multi-point support connections.
Innovation Solution
The system employs a Bluetooth Low-Energy (BLE) command to enable a second BLE-enabled device to attempt a Bluetooth Classic connection with previously paired source devices, allowing easy switching and management through a user interface with touch-screen functionality and intelligent algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct commands are sent from source devices to wearable audio devices to establish wireless connections, then the connection establishment process is straightforward, but the user cannot easily switch between source devices when limited multi-point connections are available
Solution Approach 1:
The wearable audio device maintains a pre-stored list of previously paired source devices and their connection states. When a user wants to switch devices, the system retrieves this pre-organized information and presents it through a user interface, eliminating the need for the user to manually search through pairing options or re-pair devices. This preliminary organization of connection data directly enables easy switching while managing complexity.
Solution Approach 2:
The patent introduces a BLE-enabled first device as an intermediary that receives the list of previously paired source devices from the wearable audio device and presents it to the user through a user interface. This intermediary layer simplifies the interaction by centralizing the connection management function, allowing the wearable device to focus on audio playback while the intermediary handles the complex task of displaying and managing multiple source device connections.
2Adaptability or versatility
If multiple source devices are supported with limited connections, then device versatility is improved, but the difficulty of detecting and measuring connection status increases
Solution Approach 1:
The system continuously monitors connection status between the wearable audio device and multiple source devices, maintaining an updated list that reflects current connection states. This feedback mechanism automatically tracks which devices are connected, disconnected, or available for pairing, making it easier to detect and measure connection status without requiring complex manual monitoring. The system uses this feedback to dynamically update the user interface and enable smooth switching between devices.

AI summary
Methods and systems for easily establishing or switching between wireless connections by sending a Bluetooth Low-Energy (BLE) command from a first BLE enabled device to a second BLE enabled device, where the BLE command causes the second BLE enabled device to attempt to establish a Bluetooth Classic connection with one or more source devices from a list of source devices that have previously been paired with the second BLE device. The first BLE device is configured to obtain or receive the list from the second BLE device, and in response to one or more triggers, send the BLE command. The list of previously paired source devices may be presented to a user via a display screen with touch-screen functionality, and in some examples, may utilize one or more algorithms to intelligently order the available source devices based on a variety of factors.
