In FIG. 3, only the unique code imaging unit 130 and the unique code 230 are illustrated for convenience of description, but it is obvious that other components may be further included as described above with reference to FIGS. 1 and 2.

The unique code 230 of the second device 200 may be one of a graph, a number, and a barcode of a specific pattern.

If the unique code 230 of the second device 200 is a barcode, the unique code image pickup unit 130 included in the first device 100 should have a barcode reader function and purchase goods at a large supermarket or department store. As the bar code reader recognizes the bar code, the unique code image pickup unit 130 scans the unique code 230 to capture the unique code 230, and the second device included in the corresponding image under the control of the control unit. 200 unique information is read out.

In addition, when the unique code 230 of the second device 200 is a graph or number of a specific pattern, the unique code image pickup unit 130 included in the first device 100 captures the graph or number to obtain an image. ), The unique information of the second device 200 included in the image is read by the control of the controller.

By using the information read by the above method, it is determined whether the second device based on the information read by the controller 160 is a device capable of short-range wireless communication, and generates an error message on the display unit 110. You decide whether to display it.

On the other hand, as described above, the unique code image pickup unit 130 may be a camera.

4 is a flowchart illustrating a procedure of a method for searching for a device capable of short-range wireless communication according to an embodiment of the present invention. Hereinafter, referring to the configuration of FIG. 1, the apparatus for short-range wireless communication according to the present invention will be described. Describe the basic flow of search methods.

First, the device search method according to the present invention receives a selection signal from the user as to whether to search for the second device 200 in the first device 100 (S400).

If a user receives a selection signal not to search for a device capable of short-range wireless communication, the user performs another corresponding function of the first device (S410), and receives a selection signal to search for a device capable of short-range wireless communication. In step S420, a user inputs a signal for selection of a user.

Receiving the selection signal of the user in the device search method, for example, by providing a menu to the user interface may receive a selection signal for the device search method from the user.

 In operation S430, the first device recognizes the unique code 230 when receiving the selection signal of the device searching method by the unique code from the user. In step S450, when receiving a selection signal of a device search method other than the device search method by a unique code, the device is searched by the selected other method (S440).

Here, in step S450, the first device recognizes the unique code 230. The unique code image pickup unit 130 of the first device 100 captures the unique code 230 of the second device, which is a device capable of short-range wireless communication. The method may include reading information included in the unique code from the captured unique code 230 image.

In the device search method using the unique code, the unique code image pickup unit 130 of the first device captures the unique code 230 of the second device 200 to read out the unique information included in the captured unique code. In operation S460, the method may determine whether short-range wireless communication with the corresponding second device is possible.

If the second device is a device that is not capable of short-range wireless communication or the current wireless communication is not possible (S470), an error message is displayed on the display unit 120 of the first device, and the first device recognizes the unique code 230. Returning to step S450.

On the other hand, the error message serves to inform the user that the short-range wireless communication with the device. It is obvious that the contents of the error message or the method of displaying the error message can be implemented in various ways, and the content or the display method of the error message is not limited.

Meanwhile, if the second device is capable of short-range wireless communication, a search signal for short-range wireless communication with the second device 200 having the corresponding unique code is generated, and the second device 200 is generated using the generated search signal. By allocating the same frequency band as the two devices are connected to enable short-range wireless communication (S480).

Hereinafter, the order in which the method for searching for a device capable of short-range wireless communication according to an embodiment of the present invention is performed will be described with an example of an actual user interface screen.

5 is an exemplary diagram illustrating a procedure of performing a method of searching for a device according to an embodiment of the present invention through a user interface screen of the first device 100.

First, when entering a device search mode capable of short-range wireless communication, the first device provides a user interface menu to the user to receive a user's selection of a method of searching for the second device (S500).

Thereafter, an example of a screen S510 for recognizing a unique code when a 'unique code search' menu is selected from a user is shown.

In order to facilitate the description of the present specification, the name of the user interface menu is defined as 'unique code search', and it is obvious that the name of the user interface menu can be easily changed by a person having ordinary skill in the near field communication field. to be.

Thereafter, the unique code imaging unit 130 of the first device captures the unique code 230 of the second device, reads out the unique information of the second device included in the unique code, and then controls the 160 of the first device. In step 2, it is determined whether short-range wireless communication with the second device 200 is possible.

When short-range wireless communication with the second device 200 is possible, the controllers 160 and 260 transmit and receive units 150 of both devices to perform short-range wireless communication between the first device 100 and the second device 200. , S520 is an example of a user interface screen for connecting both devices by controlling 250.

On the other hand, an example (S530) of a screen displaying an error message when the short range wireless communication with the corresponding second device 200 is not shown.

Although the steps S520 and S530 are shown in FIG. 5 to facilitate the description in this specification, the contents of the user interface screen and the error message can be easily changed to those having ordinary skill in the near field communication field. It's work.

Although the present invention has been described with reference to the embodiments, those skilled in the art may variously modify and modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. It will be appreciated that it can be changed.

As described above, the present invention provides a method for searching for a device capable of short-range wireless communication, wherein the first device does not search for all devices capable of short-range wireless communication existing in a communication area, and directly searches for the second device using a unique code. Searching has the advantage of reducing the time spent searching for devices.

Since the present invention does not need to search for a short-range wireless communication device that is not desired by the user, the user does not go through a process of selecting among unnecessary devices, which is advantageous in that the user can use the short-range wireless communication.
