Bluetooth Connection Automation via Intermediary Device Address Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Bluetooth communication methods require a separate connection operation to connect a new electronic device with one that supports Bluetooth, involving suspension of existing connections and a new pairing process.
Innovation Solution
An electronic device that receives a connection request from a second external device using shared Bluetooth communication information from a first external device, performs a page scan, and establishes a connection with the second device without a separate connection operation, using its processor and wireless communication circuit to identify and provide a user interface for connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate connection operation is performed to connect a new electronic device, then connection reliability is ensured through proper pairing, but connection time increases and user convenience deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-storing Bluetooth communication information (device addresses, pairing keys) of previously connected devices in the electronic device's memory. When a new connection is needed, the device performs a page scan using this pre-stored information to automatically initiate connection without requiring the user to manually search or pair, thus reducing connection time while maintaining reliability through verified pairing data.
Solution Approach 2:
The patent uses copying by replicating the Bluetooth communication information from the first external device to the electronic device. The electronic device receives and stores a copy of the second device's Bluetooth address and connection information, allowing it to directly connect to the second device without repeating the full pairing process, thereby reducing connection time while ensuring connection reliability through copied authentication data.
2Reliability
If manual connection operation is required for each new device, then connection security is maintained through user confirmation, but ease of operation deteriorates
Solution Approach 1:
The patent applies self-service by enabling the electronic device to automatically perform the connection initiation process using pre-stored Bluetooth information. The device autonomously executes page scans, identifies target devices, and establishes connections without requiring manual user input for each connection attempt, significantly improving ease of operation while maintaining security through the use of pre-verified pairing information.
Solution Approach 2:
By pre-storing Bluetooth communication information including device addresses and pairing credentials, the system eliminates the need for repeated manual pairing operations. The preliminary storage of authentication data allows automatic reconnection while maintaining security, as the pre-stored information is already verified and trusted.
3Productivity
If Bluetooth information is shared from first external device, then connection efficiency improves by avoiding separate pairing, but information security may be compromised
Solution Approach 1:
The patent uses the first external device as an intermediary to transfer Bluetooth communication information to the electronic device. Instead of direct exposure or broadcasting of sensitive pairing data, the information is securely transmitted through the trusted intermediary (first device), which acts as a bridge. This maintains information security while enabling efficient automatic connection, as the intermediary ensures only authorized devices receive the Bluetooth information.

AI summary
An electronic device includes a display; a first wireless communication circuit configured to support Bluetooth (BT) communication and to include a first BT address; a processor operatively connected to the display and the first wireless communication circuit; and a memory, wherein the memory may store instructions that are configured to, when executed, cause the processor to: receive first data including a second BT address associated with a first external device; perform a page scan based on the first BT address and the second BT address using the BT communication; receive second data based on the second BT address from a second external device using the BT communication; identify information for connection with the second external device based on the second data using the BT communication; and provide a user interface for connection with the second external device through the display based on the identified information.
