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.

- 12. A method for warning abnormal connection between two bluetooth devices using preset comparison value, adjusting a distance between two connected bluetooth devices, taking an average value obtained from several quality testing values read at said distance as a comparison value, and getting link quality values, then comparing said link quality values with said comparison value to confirm the connection situation of said devices.
- 22. A bluetooth device, mainly comprising a bluetooth module, a memory and a CPU, said bluetooth being consisted of a RF unit and a baseband unit, and said RF unit being connected to an antenna, said CPU being connected to a warning device and instructing said warning device to emit warning by commands to mention a user of said bluetooth device.
