<P>PROBLEM TO BE SOLVED: To provide a method of warning abnormal connection in Bluetooth device capable of setting. <P>SOLUTION: The major object of this invention is to provide a method for warning abnormal connection between two Bluetooth devices whose connection is built, allows a user to adjust a distance between two connected Bluetooth devices and to take an average of link quality values obtained through several times of inspections read at that distance as a comparison value, a CPU of any one of the devices inspects link quality value periodically by a host controller interface (HCI) command. The CPU sends out a warning message to mention the user of the Bluetooth device when the quality value is lower than the comparison value, i.e., the connection is abnormal. Then, the user can handle it immediately, for example, pulls the two devices closer to lower the probability of the connection interruption. <P>COPYRIGHT: (C)2003,JPO |
