Bluetooth LE Control Device for Interface-Less Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth devices without a user interface face challenges in controlling connections, managing operations, and setting passwords, making it difficult to establish and manage connections efficiently.
Innovation Solution
A method and apparatus using Bluetooth technology that allows a control device to control another device by receiving advertising messages, establishing connections, requesting feature information, and setting or changing passwords through a Generic Attribute Profile (GATT) structure, enabling secure and efficient operation management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If Bluetooth devices are designed without display or user interface to reduce complexity and cost, then device complexity and cost are reduced, but the ability to control connections, manage operations, and set passwords deteriorates
Solution Approach 1:
The patent introduces a control device as an intermediary between the user and Bluetooth devices without user interfaces. The control device receives user inputs, processes control commands, and manages Bluetooth connections and operations on behalf of the target devices. This mediator approach enables devices to remain simple while maintaining full operational control through an external controller.
2Length of stationary object
If Bluetooth transmission distance is extended beyond 100m, then communication range is improved, but power consumption and signal stability deteriorate
Solution Approach 1:
The control device serves as a relay or gateway that extends the effective communication range. Instead of requiring the Bluetooth device to transmit over long distances directly, the control device receives signals within normal Bluetooth range and forwards commands or data to remote targets, effectively extending the system's reach without increasing the power consumption of the Bluetooth device itself.

AI summary
Provided are a method and an apparatus for controlling device using Bluetooth technology. A method of controlling a first device by a control device using Bluetooth includes receiving an advertising message including service information indicating whether a device control service is supported from the first device, establishing a Bluetooth LE connection with the first device when the first device supports the device control service, transmitting a read request message to the first device to request feature information related to a controllable operation mode and procedure supported by the first device, receiving a read response message including the feature information in response to the read request message, transmitting a first write request message for requesting writing of a control characteristic for controlling a specific operation related to pairing and connection of the first device based on the supported feature information, and receiving a first write response message in response to the first write request message. Here, the write request message includes control information related to the specific operation.
