Method and device for controlling device using Bluetooth in wireless communication system

1. A method for being controlled by a control device performed by a first device using a Bluetooth LE, the method comprising:

establishing a Bluetooth LE connection with the control device;

receiving a write request message requesting a specific operation with the second device from the control device;

transmitting a write response message in response to the request message;

transmitting a request message to the second device in order to perform the specific operation; and

transmitting an error message indicating that a performance of the specific operation is failed to the control device, when failing to perform the specific operation with the second device within a specific time,

wherein the request message includes time information indicating the specific time.

2. The method of claim 1 ,

wherein the error message includes reason information indicating the cause of the failure of performing the specific operation.

3. The method of claim 2 ,

wherein the reason information indicates one of a failure to receive a response to the request message message, an encryption key mismatch, the first device performing another operation, or the second device not being an acceptable device.

4. The method of claim 1 ,

wherein the specific operation is establishing the Bluetooth LE connection with the second device.

5. The method of claim 1 , wherein the step of establishing the Bluetooth LE connection with the control device further comprises,

transmitting an advertising message to the control device; and

receiving a connection request message for the Bluetooth LE connection from the control device.

6. A method for controlling a first device performed by a control device using a Bluetooth LE, the method comprising:

establishing a Bluetooth LE connection with at least one of the first device or a second device;

receiving a write request message requesting a specific operation with at least one of the first device or the second device;

receiving a write response message in response to the request message;

receiving a message indicating a performance result of the specific operation within a specific time from at least one of the first device or the second device; and

outputting the performance result of the specific operation.

7. The method of claim 6 ,

wherein the message further includes reason information indicating a failure reason, when failing to perform the specific operation.

8. The method of claim 7 ,

wherein the step of outputting the performance result includes outputting the failure reason together with the performance result.

9. The method of claim 6 ,

wherein the error reason indicates one of a failure to receive a response to the request message, an encryption key mismatch, performing another operation, or target device not being an acceptable device.

10. A first device being controlled by a control device using a Bluetooth LE, the first device comprising:

a communication unit for communicating with external devices in wireless or wired manner; and

a processor functionally connected to the communication unit,

wherein the processor is configured to:

establishing a Bluetooth LE connection with the control device;

receiving a write request message requesting a specific operation with a second device from the control device;

transmitting a write response message in response to the request message;

transmitting a request message to the second device in order to perform the specific operation; and

transmitting an error message indicating that a performance of the specific operation is failed to the control device, when failing to perform the specific operation with the second device within a specific time,

wherein the request message includes time information indicating the specific time.
