receiving, from a second device, an advertising message including information associated with the other communication interfaces;

transmitting, to the second device, a request message for requesting detailed information of the other communication interfaces based on the information;

receiving, from the second device, a response message including the detailed information as a response to the request message;

forming a Bluetooth low energy (LE) connection with the second device;

activating the other communication interfaces by using Bluetooth low energy (LE); and

forming the connection with the second device,

wherein the advertising message is transmitted through a specific channel for a Bluetooth low energy (LE) connection,

wherein the information includes ID information for distinguishing the other communication interfaces, location information of the detailed information, status information on a status of the second device and capability information of the other communication interface, and

wherein the location information on a location of a plurality of specific information for connecting the other communication interfaces is used to obtain the plurality of the specific information for connecting the other communication interfaces after forming the Bluetooth low energy (LE) connection between the first device and the second device.

2. The method of claim 1, wherein at least one of a scan response message or a GATT data base is included in the location information.

3. The method of claim 1, wherein the detailed information includes at least one of channel information for the connection, MAC address information of the second device, network type information, or channel type information, and

wherein the method further comprises:

obtaining the MAC address information of the second device by using the location information.

4. The method of claim 1, wherein the request message and the response message are transmitted or received through the specific channel.

5. The method of claim 1, wherein forming the Bluetooth low energy (LE) connection further comprises:

transmitting a Bluetooth low energy (LE) connection request message to the second device;

receiving a Bluetooth low energy (LE) connection response message from the second device as a response to the Bluetooth low energy (LE) connection request message; and

connecting with the second device through the Bluetooth low energy (LE), and

wherein the request message and the response message are transmitted or received through a data channel for transmitting or receiving data of Bluetooth low energy (LE).

6. The method of claim 1, further comprising:

transmitting, to the second device, a connection request message for the connection; and

receiving, from the second device, a response message as a response to the connection request message.

7. The method of claim 6, wherein the connection request message includes a command for the connection, and

the response message includes result information for the command and reason information for a failure when the result information shows the failure.

8. The method of claim 1, wherein the information further includes service information supported by the other communication interfaces, and the ID information, the location information, the capability information, and the service information are included in a bit format.

9. A first device in a method for forming a connection using other communication interfaces through Bluetooth low energy (LE) in a wireless communication system, the first device comprising:
