A communication apparatus includes a first notification unit, a second notification unit, a reception unit, and a sharing unit. The first notification unit provides first information containing information unique to the communication apparatus and information on a predetermined channel for use in sharing a communication parameter for wireless communication with a different communication apparatus. The second notification unit provides second information containing the information unique to the communication apparatus but not containing information on the predetermined channel. When the first information is provided, the reception unit waits to receive a predetermined signal containing information corresponding to the information unique to the communication apparatus without shifting to another channel. When the second information is provided, the reception unit waits to receive the predetermined signal using a plurality of channels. When the predetermined signal is provided, the sharing unit shares the communication parameter with the different communication apparatus.

Communication apparatus, method of sharing, and program

A communication apparatus receives request regarding a wireless communication parameter setting from another apparatus that has obtained information regarding the communication apparatus by capturing an image indicating information regarding the communication apparatus, accepts a user input regarding whether the parameter setting is to be executed with the other apparatus in a case where the request has been received, and executes the parameter setting with the other apparatus in a case where the user input indicating that a parameter setting is to be executed with the other apparatus has been accepted.
