receive the identifier from the first external electronic device through the USB connector,
determine whether a first group corresponding to the identifier is included in a group management list stored in the memory, wherein the first group includes at least one external electronic device for performing wireless communication with the first external electronic device without performing a discovery procedure, an owner determination procedure, or an authentication procedure,
when the first group is included in the group management list, determine the first group as a group for performing the wireless communication, wherein the electronic device operates as a group owner of the first group, and
when the first group is not included in the group management list, generate a second group corresponding to the identifier and store the second group in the group management list, wherein the electronic device operates as a group owner of the second group,
wherein the instructions further cause the processor to:
generate a wireless signal packet including the identifier of the first external electronic device,
receive a probe request from a second external electronic device through the wireless communication circuit,
transmit the wireless signal packet including the identifier of the first external electronic device to the second external electronic device through the wireless communication circuit, and
establish a wireless communication channel with the second external electronic device after transmitting the wireless signal packet.
2. The electronic device as claimed in claim 1 , wherein the wireless signal packet includes a device name field including the identifier.
3. The electronic device as claimed in claim 1 , wherein the wireless signal packet includes an information field including the identifier.
4. The electronic device as claimed in claim 1 , wherein the identifier includes a medium access control (MAC) address of the first external electronic device.
5. A method for operating an electronic device, comprising:
determining whether a USB connector included in the electronic device is electrically connected to a first external electronic device having an identifier;
receiving the identifier from the first external electronic device through the USB connector;
determining whether a first group corresponding to the identifier is included in a group management list stored in a memory included in the electronic device, wherein the first group includes at least one external electronic device for performing wireless communication with the first external electronic device without performing a discovery procedure, an owner determination procedure, or an authentication procedure;
when the first group is included in the group management list, determining the first group as a group for performing the wireless communication, wherein the electronic device operates as a group owner of the first group; and
when the first group is not included in the group management list, generating a second group corresponding to the identifier and store the second group in the group management list, wherein the electronic device operates as a group owner of the second group,
wherein the method further comprises:
generating a wireless signal packet including the identifier of the first external electronic device,
receiving a probe request from a second external electronic device through a wireless communication circuit included in the electronic device;
transmitting the wireless signal packet including the identifier of the first external electronic device to the second external electronic device through the wireless communication circuit; and
establishing a wireless communication channel with the second external electronic device after transmitting the wireless signal packet.
6. The method for operating the electronic device as claimed in claim 5 , wherein the wireless signal packet includes a device name field including the identifier.
7. The method for operating the electronic device as claimed in claim 5 , wherein the wireless signal packet includes an information field including the identifier.
8. The method for operating the electronic device as claimed in claim 5 , wherein the identifier includes a MAC address of the first external electronic device.
9. A system comprising:
an electronic device configured to:
receive, from a first external electronic device having an identifier, the identifier through a USB connector;
determine whether a first group corresponding to the identifier is included in a group management list stored in a memory, wherein the first group includes at least one external electronic device for performing wireless communication with the first external electronic device without performing a discovery procedure, an owner determination procedure, or an authentication procedure;
when the first group is included in the group management list, determine the first group as a group for performing the wireless communication, wherein the electronic device operates as a group owner of the first group; and
when the first group is not included in the group management list, generate a second group corresponding to the identifier and store the second group in the group management list, wherein the electronic device operates as a group owner of the second group, and
a second external electronic device configured to transmit a probe request to the electronic device, wherein
in response to the probe request, the electronic device transmits a wireless signal packet including the identifier of the first external electronic device to the second external electronic device, and the second external electronic device establishes a wireless communication channel with the electronic device based on the identifier of the first external electronic device.
