    • According to one embodiment, a communication module executes close proximity wireless transfer. A connection control module establishes a connection between the communication module and an external device which are in a close proximity state when the communication module is in an unconnected state, and releases the connection when a period in which a response from the external device is absent exceeds a connection time-out value. A communication control module executes a service by close proximity wireless transfer. A detection module detects a start and a stop of the service. A change module changes the connection time-out value in response to detection of the start and the stop of the service, in such a manner that the connection time-out value during a period in which the service is being executed is greater than the connection time-out value during a period in which the service is not executed.

    • According to one embodiment, an electronic device includes a communication module, a connection establishment module, a negotiation module, a service execution module, and an execution control module. The communication module executes close proximity wireless transfer. The connection establishment module establishes a connection between the communication module and an external device which are in a close proximity state. The negotiation module determines a service to be executed between the communication module and the external device through a negotiation process when the connection is established. The service execution module executes the service. The execution control module executes the negotiation process again in response to a user's request or a request from the external device if the connection is kept after the completion of the service.
