Bluetooth Low Energy Auto Power-On Connection Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems, particularly those using Bluetooth, face challenges in managing connected states, especially when a device is in a powered-off state with an auto power-on function enabled, leading to issues where another terminal is inhibited from connecting via Bluetooth due to ongoing connections.
Innovation Solution
A communication apparatus with a first communication portion for Bluetooth Low Energy communications and a determiner to manage auto power-on functions, disconnecting existing connections and transmitting advertising information upon a power-off instruction to allow reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication apparatus maintains Bluetooth connection in powered-off state with auto power-on function enabled, then power consumption is reduced and connection stability is improved, but another terminal cannot connect to the apparatus via Bluetooth
Solution Approach 1:
The communication apparatus performs preliminary disconnection of the first Bluetooth connection before establishing a second Bluetooth connection. This preliminary action ensures that when a new connection request arrives, the apparatus is already in a state ready to accept the new connection, resolving the contradiction between maintaining stable connections and allowing multiple terminal connectivity.
Solution Approach 2:
The Bluetooth communication state of the apparatus is made dynamic by automatically disconnecting the first connection when a second connection is established. This dynamic state transition allows the apparatus to adapt between maintaining connection stability and enabling multiple terminal connectivity based on real-time connection requests.
2Adaptability or versatility
If the apparatus disconnects Bluetooth connection upon power-off instruction, then another terminal can connect, but the auto power-on function may not work properly when needed
Solution Approach 1:
The disconnection action is applied selectively only to Bluetooth connections when a power-off instruction is received, while leaving other power management functions intact. This localized application of disconnection ensures that terminal connectivity is improved without compromising the overall reliability of the auto power-on function.
3Duration of action of stationary object
If the apparatus remains connected to external communication apparatus via Bluetooth in powered-off state, then connection stability is maintained, but the apparatus cannot connect to another terminal
Solution Approach 1:
The apparatus performs preliminary disconnection of existing Bluetooth connections before accepting new connection requests. This ensures that the connection duration is optimized for each individual connection while maintaining the ability to connect to multiple terminals sequentially, resolving the contradiction between connection duration and number of simultaneous connections.

AI summary
Provided is a communication apparatus including: a first communication portion configured to perform wireless communications with an external apparatus based on a Bluetooth Low Energy communication scheme; and a first determiner configured to determine whether an auto power-on function of powering on the communication apparatus under a predetermined condition even when the communication apparatus is in a powered-off state is set to be enabled, wherein, when the first determiner determines that the auto power-on function is set to be enabled, the first communication portion disconnects connection to the external apparatus, which has been established based on the Bluetooth Low Energy communication scheme, in response to a power-off instruction, and transmits advertising information that allows a response based on the Bluetooth Low Energy communication scheme to be received.
