Display Bluetooth Pairing With LE Audio Support Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a device control method to identify and connect with Bluetooth Low Energy Audio (LE Audio) compatible devices, as the increasing number of devices support this new protocol, requiring a method to differentiate and manage LE Audio devices effectively.
Innovation Solution
A display apparatus and method that includes device scanning, Bluetooth connection establishment, and displaying a preset indicator for LE Audio protocol support, using UUID identification to determine LE Audio compatibility and manage connections accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If device scanning and Bluetooth connection establishment are performed for all scanned devices, then connection compatibility is improved, but device complexity and protocol management difficulty increase due to multiple Bluetooth protocols (Classic Bluetooth and LE Audio)
Solution Approach 1:
The patent applies preliminary action by checking the UUID of scanned devices before establishing Bluetooth connections. The system performs protocol identification (determining whether a device supports LE Audio or Classic Bluetooth) in advance, which allows for appropriate protocol selection and avoids connection failures. This preliminary UUID verification step resolves the contradiction by enabling compatibility without requiring complex runtime protocol management.
2Reliability
If UUID identification is implemented to determine LE Audio protocol support, then protocol compatibility is improved, but information processing time increases during device pairing
Solution Approach 1:
The patent performs UUID identification as a preliminary action during the device scanning phase, before actual connection establishment. By determining LE Audio support status in advance through UUID checking, the system avoids repeated connection attempts and protocol negotiation delays, thereby reducing overall pairing time while maintaining high protocol compatibility.
3Loss of information
If LE Audio protocol support is indicated through preset indicators, then user awareness of protocol capabilities is improved, but display interface complexity increases
Solution Approach 1:
The patent applies local quality by adding preset indicators specifically at the device list display location where scanned devices are shown. Rather than redesigning the entire display interface, the solution locally enhances protocol capability visibility by inserting LE Audio support indicators next to device names or icons. This targeted approach maintains overall interface simplicity while effectively communicating protocol capabilities to users.

AI summary
Disclosed are a display apparatus and a method therefor. The method includes: controlling a Bluetooth communication module of the display apparatus to perform device scanning, and displaying scanned devices on a display of the display apparatus; in response to a pairing request triggered for a target device among the scanned devices, establishing a Bluetooth connection based on an A2DP protocol with the target device; obtaining a UUID of the target device; after successfully establishing the Bluetooth connection based on the A2DP protocol, adding the target device to a list of connected devices; determining, based on the UUID, that the target device supports a LE Audio protocol, adding a preset visual indicator for the target device; where the preset visual indicator is used to prompt a user that the Bluetooth connection with the target device is allowed to be switched to a Bluetooth connection based on the LE Audio protocol.
