  • Patent number: 11018868
    Abstract: The present invention relates to a communication apparatus including a receiving unit and a restricting unit. The receiving unit is configured to receive a signal from another communication apparatus after code information is displayed by a display control unit. The signal includes identification information indicated by the code information. The code information is information in which information necessary for performing a sharing process for sharing a communication parameter for radio communication among apparatuses is coded. The restricting unit is configured to restrict execution of the sharing process when the communication apparatus has received the signal including the identification information from a plurality of other communication apparatuses with the receiving unit.
