Communication apparatus for executing service, control method and storage medium therefor, and communication system

A control method for a communication apparatus, the communication apparatus including communication unit that execute a predetermined service by communicating with an external apparatus, the communication unit being communication unit that establish a connection with the external apparatus and communicate data for executing the predetermined service with the external apparatus, the control method for the communication apparatus comprising:

• controlling the communication unit so that the communication apparatus operates as a first role in the case of connecting to a first external apparatus operating as a second role, and so that the communication apparatus operates as the second role in the case of connecting to a second external apparatus operating as the first role,
• wherein in the controlling, the communication unit is controlled so that the communication apparatus operates as the second role to connect to the second external apparatus operating as the first role in between times when the communication apparatus carries out a process for operating as the first role and periodically transmitting a predetermined signal.
