A communication apparatus that performs wireless communication with an external apparatus, comprising:
- a display control unit configured to control a display unit so as to display a predetermined screen related to an operation of the external apparatus;
- and
- a detection unit configured to detect a wireless signal transmitted from the external apparatus while no network with the external apparatus is formed,
- wherein when specific information is included in a wireless signal detected by the detection unit, the display control unit controls the display unit so as to display a help screen corresponding to the specific information while no network with the external apparatus is formed.
A communication apparatus that performs wireless communication with an external apparatus, comprising:
- a display control unit configured to display a predetermined screen related to an operation of the external apparatus;
- and
- a detection unit configured to detect a wireless signal transmitted from the external apparatus while no network with the external apparatus is formed,
- wherein when specific information is included in a wireless signal detected by the detection unit, the display control unit controls so as to display a predetermined screen corresponding to the specific information while no network with the external apparatus is formed, and
- the predetermined screen corresponding to the specific information comprises a screen related to an operation not related to communication between the communication apparatus and the external apparatus.
A communication apparatus that performs wireless communication with an external apparatus present within a predetermined range, comprising:
- an operation unit configured to operate the communication apparatus;
- a transmission unit configured to transmit a wireless signal that notifies the presence of the communication apparatus to the external apparatus while no network with the external apparatus is formed, wherein the wireless signal includes operation information indicating an operation type or an operation state of the external apparatus;
- an update unit configured to update, when the operation unit is operated, the operation information included in the wireless signal;
- and
- a control unit configured to control the transmission unit so as to transmit a wireless signal in which the operation information has been updated by the update unit.
