Abstract: 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.

Abstract: Disclosed is a method for connecting, by a first device, with a second device using Bluetooth communication. The method includes transmitting a request message to request user information for identifying a user of the second device to the second device, receiving a response message including the user information from the second device, registering the second device to a first authority policy or a second authority policy based on the user information, and establishing a Bluetooth connection with the second device registered to the first authority policy or the second authority policy. The first authority policy indicates a first control authority for controlling an operation of the first device, the second authority policy indicates a second control authority for controlling an operation of the first device, the first control authority indicates a control authority capable of controlling an operation of the first device within a limited range, the second control authority indicates a control authority capable of controlling all of operations of the first device.
