Abstract

An in-vehicle apparatus selects, as a profile connection mode, one connection mode out of a first connection mode and a second connection mode, and performs profile connection using the selected one connection mode. The first connection mode is to transmit a profile connection request signal to a communication partner so as to start a connection procedure; the second connection mode is to wait for reception of a profile connection request signal from the communication partner for a predetermined time so as to start the connection procedure. When the profile connection using the selected one connection mode fails, a connection procedure using the other connection mode that was not selected previously is started. When the profile connection using the other connection mode is successful, upon occurrence of a next profile connection request, the other connection mode is selected as a profile connection mode.

Description

technical field [0001] The present disclosure relates to a short-distance wireless communication device that can alternatively select one of a first connection mode and a second connection mode to start a connection process as a predetermined communication protocol connection mode; the first connection mode is used to send a predetermined connection mode to a communication partner device The communication protocol connection request signal is used to start the communication process, and the second connection mode is used to wait for a predetermined time to receive a predetermined communication protocol connection request from the communication partner device. Background technique [0002] [Patent Document 1] JP 2008-273370A (US 2008 / 0269961) [0003] [Patent Document 2] JP 2009-253601A (US 2009 / 0253466) [0004] [Patent Document 3] JP 2009-253603A (US 2009 / 0253466) [0005] A short-range wireless communication module integrated in a short-range wireless communication devic...
