Bluetooth Low Energy Mode Switching for Connected Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques require user operation of a printing apparatus to switch from direct wireless communication mode, lacking the ability for a mobile terminal to instruct the apparatus to end direct wireless communication mode, especially when multiple devices are connected.
Innovation Solution
A communication apparatus with a wireless communication unit that connects to a printing apparatus in direct wireless communication mode via Bluetooth Low Energy, determining whether to stop the direct wireless communication mode based on information acquired, allowing the mobile terminal to instruct the printing apparatus to end the mode only when alone connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the printing apparatus operates in direct wireless communication mode, then wireless communication between the communication apparatus and the printing apparatus is enabled, but the communication mode cannot be switched when multiple terminals are connected
Solution Approach 1:
The printing apparatus automatically determines the number of connected terminals and decides whether to switch communication modes without requiring manual user input. The system self-evaluates the connection status and autonomously makes the mode switching decision, eliminating the need for complex user operations.
Solution Approach 2:
The printing apparatus receives feedback information from connected terminals about their connection status, processes this information to determine the number of connected devices, and based on this feedback, decides whether to maintain or switch communication modes. This feedback mechanism enables intelligent adaptive control.
2Ease of operation
If the user operates the printing apparatus to switch communication mode, then the communication mode can be changed, but the mobile terminal cannot instruct the printing apparatus to end direct wireless communication mode
Solution Approach 1:
The communication apparatus is designed to function both as a client device that connects to the printing apparatus and as a control device that can instruct the printing apparatus to switch modes. The terminal device has multi-functional capabilities including connection management, mode control, and status monitoring, eliminating the need for separate control operations.
Solution Approach 2:
The printing apparatus acts as an intermediary that receives control instructions from the mobile terminal, processes these instructions along with connection status information, and executes the appropriate mode switching actions. This intermediary role enables seamless control from the terminal to the printing apparatus.
3Adaptability or versatility
If the printing apparatus allows mode switching when multiple terminals are connected, then communication flexibility is improved, but connection interruption may occur for other connected devices
Solution Approach 1:
The printing apparatus performs preliminary evaluation of the connection status before allowing mode switching. It first determines the number of connected terminals, and only if the count indicates safety for mode switching does it proceed with the mode change. This preliminary check prevents connection interruptions for other devices.
Solution Approach 2:
The system takes preliminary protective action by checking connection status before mode switching to prevent harmful effects. By anticipating potential connection issues and blocking mode switches when multiple terminals are connected, the system prevents connection interruptions before they can occur.

AI summary
In a case where a communication apparatus receives an instruction for making a printing apparatus stop operation of a direct wireless communication mode, the communication apparatus determines whether to make the printing apparatus stop the operation of the direct wireless communication mode based on information acquired from the printing apparatus through Bluetooth® Low Energy communication.
