Abstract

A communication device acquires information relating to a first access point from a captured first image, and acquires information relating to a second access point from a captured second image. The communication device then starts communication parameter share processing of sharing a communication parameter, required for establishing a wireless network, with respect to the first access point or the second access point. The communication device starts the communication parameter share processing with respect to the second access point in response to reception of a completion notification indicative of completion of the communication parameter share processing with respect to the first access point, from the first access point.

Claims

1. A communication device comprising:

an execution unit configured to use information acquired by another communication device by said another communication device capturing an image, and execute communication parameter share processing of sharing a communication parameter required for establishing a wireless network with said another communication device;

a reception unit configured to receive information on an access point, on which the communication parameter share processing is to be executed, from said another communication device; and

a start unit configured to start communication parameter share processing of sharing the communication parameter with the access point on the basis of the information received by the reception unit after the communication parameter share processing is executed by the execution unit.

2. The communication device according to claim 1, wherein the communication device is an access point.

3. The communication device according to claim 1, wherein the reception unit receives the information on the access point, on which the communication parameter share processing is to be executed, in the communication parameter share processing executed with said another communication device.

4. The communication device according to claim 1, wherein the communication parameter includes at least one of a network identifier of the wireless network, an encryption scheme, an encryption key, an authentication scheme, and an authentication key.

5. The communication device according to claim 1, wherein the wireless network is a network of a wireless local area network in conformity with IEEE 802.11 series.

6. The communication device according to claim 1, wherein the image includes a barcode or a two-dimensional code.

7. A communication method comprising:

using information acquired by another communication device by said another communication device capturing an image, and executing communication parameter share processing of sharing a communication parameter required for establishing a wireless network with said another communication device;

receiving information on an access point, on which the communication parameter share processing is to be executed, from said another communication device; and

starting communication parameter share processing of sharing the communication parameter with the access point on the basis of the information received from said another communication device after the communication parameter share processing is executed with said another communication device.

8. A non-transitory computer-readable storage medium storing a program for causing a communication device to execute processes, the processes comprising:

using information acquired by another communication device by said another communication device capturing an image, and executing communication parameter share processing of sharing a communication parameter required for establishing a wireless network with said another communication device;

receiving information on an access point, on which the communication parameter share processing is to be executed, from said another communication device; and

starting communication parameter share processing of sharing the communication parameter with the access point on the basis of the information received from said another communication device after the communication parameter share processing is executed with said another communication device.
