4 and 6, a method of providing a warning of a Bluetooth memory device 100 according to an embodiment of the present invention, first, as a device signal identification step S200, the Bluetooth memory device 100 to which the application program 210 is linked. Receiving device signal periodically from) to identify whether it is connected normally.

Next, as a distance calculation step according to the magnitude of the device signal (S210), calculating the distance between the Bluetooth memory device 100 and the portable terminal 200 according to the magnitude of the device signal received by the application program 210 ( S210).

Subsequently, the application program 210 compares the device signal with a threshold value (S220), and when the device signal is less than or equal to the threshold value, that is, when the distance between the two devices is far apart, the notification and warning signals through the display 220 and the motor unit 250. It will be output (S230). If the device signal is less than the threshold in step S220, as the distance between the two devices is determined not to be far apart, the device signal identification step (S200) is repeated.
