According to one embodiment, a connection control module is configured to transmit a connection request signal during a period in which a communication module is in an unconnected state, and to establish a connection between the communication module and an external device which are in a close proximity state. A halt module is configured to halt a communication control module from executing a negotiation with the external device, when the connection between the communication module and the external device is released by the connection release request signal from the external device and thereafter the connection between the communication module and the external device is re-established by the connection control module.
