Abstract

A short-range wireless communication device used with a communication partner terminal (2) that executes a cooperative application by switching a foreground or a background, and disconnects the protocol by moving the cooperative application from the foreground to the background while a protocol is connected with the wireless communication device, the short-range wireless communication device being provided with a control device (14) for determining if the condition for returning the cooperative application from the background to the foreground is met, determining if the cooperative application has returned to the foreground on the basis of the operating situation of an application in the communication partner terminal when the condition is met, and transmitting the protocol connection request to the communication partner terminal (2) when the cooperative application has returned to the foreground. When the cooperative application has not returned to the foreground, the control device (14) repeatedly acquires the operating situation.

Description

[0001] Cross References to Related Applications [0002] This application is based on the JP Patent application 2012-121924 for which it applied on May 29, 2012, The description content is used here. technical field [0003] The present application relates to a short-distance wireless communication device used together with a communication partner terminal. In a state where the communication partner terminal is connected to the short-distance wireless communication device according to a predetermined protocol, the foreground or background can be switched to perform communication with the short-distance wireless communication device. A collaborative application that provides services cooperatively from wireless communication devices. Background technique [0004] Conventionally, there has been provided a vehicle communication system in which a portable communication terminal called a smartphone carried by a user, for example, and a short-range wireless communication device mo...
