<P>PROBLEM TO BE SOLVED: To quickly solve the problem, if any, which is caused by power-saving mode operation of the data communication counterpart. <P>SOLUTION: An in-vehicle apparatus 2, when a BT module 5 and a BT module 24 of a mobile phone 3 as the communication counterpart are connected via SPP, for example, which defines virtual serial-port data communication, transmits a power-saving mode release signal from its BT module 5 to the BT module 24. Thus, even when the BT module 24 as the data communication counterpart is operating in a power-saving mode, the in-vehicle apparatus causes the BT module 24 to promptly transit from a power-saving mode to a normal mode and to operate in a normal mode. <P>COPYRIGHT: (C)2013,JPO&INPIT |
