ABSTRACT:
A method for warning abnormal connection between two bluetooth devices allows a user to adjust a distance between two connected bluetooth devices and to take an average obtained from several quality values read at that distance as a comparison value. Thereafter, a CPU of any one of the devices gets link quality value periodically by a host controller interface (HCI) command. The CPU will send 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. And then, the user can handle it immediately, for example, pulls the two devices closer to lower the probability of the connection termination. The invention can reach the abnormal connection warning requirements for different users, and allows different users to have abnormal connection warning establishment for different distances.
