A method for using a BLUETOOTH connection in a mobile terminal, comprising: detecting, by a controller of the mobile terminal, connectable BLUETOOTH devices (108, 110, 112) in the vicinity of the mobile terminal; determining whether there is at least one priority-registered BLUETOOTH device among the detected BLUETOOTH devices, wherein a priority-registered BLUETOOTH device is a BLUETOOTH device whose priority is registered in the mobile terminal; when there is at least one priority-registered BLUETOOTH device among the detected BLUETOOTH devices, outputting on a display of the mobile terminal, by the controller, a connection confirmation message which is a message for notifying a user of the mobile terminal of the detection of a high-priority BLUETOOTH device, which is a highest-priority BLUETOOTH device among the detected BLUETOOTH devices, and allowing the user to determine whether to connect with the highest-priority BLUETOOTH device; connecting with the highest-priority BLUETOOTH device among the detected BLUETOOTH devices, when the user selects to connect with the highest-priority BLUETOOTH device; determining whether another previously connected but currently disconnected BLUETOOTH device is detected, when the connection with the currently connected highest-priority BLUETOOTH device is released; when the another previously connected but currently disconnected BLUETOOTH device is detected, connecting with the another previously connected but currently disconnected BLUETOOTH device; and when the another previously connected but currently disconnected BLUETOOTH device is not detected, detecting at least one connectable BLUETOOTH device, detecting at least one priority-registered BLUETOOTH device among the detected at least one device, and connecting with the highest-priority BLUETOOTH device among the detected BLUETOOTH devices. detecting, by a controller of the mobile terminal, connectable BLUETOOTH devices (108, 110, 112) in the vicinity of the mobile terminal; determining whether there is at least one priority-registered BLUETOOTH device among the detected BLUETOOTH devices, wherein a priority-registered BLUETOOTH device is a BLUETOOTH device whose priority is registered in the mobile terminal; when there is at least one priority-registered BLUETOOTH device among the detected BLUETOOTH devices, outputting on a display of the mobile terminal, by the controller, a connection confirmation message which is a message for notifying a user of the mobile terminal of the detection of a high-priority BLUETOOTH device, which is a highest-priority BLUETOOTH device among the detected BLUETOOTH devices, and allowing the user to determine whether to connect with the highest-priority BLUETOOTH device; connecting with the highest-priority BLUETOOTH device among the detected BLUETOOTH devices, when the user selects to connect with the highest-priority BLUETOOTH device; determining whether another previously connected but currently disconnected BLUETOOTH device is detected, when the connection with the currently connected highest-priority BLUETOOTH device is released; when the another previously connected but currently disconnected BLUETOOTH device is detected, connecting with the another previously connected but currently disconnected BLUETOOTH device; and when the another previously connected but currently disconnected BLUETOOTH device is not detected, detecting at least one connectable BLUETOOTH device, detecting at least one priority-registered BLUETOOTH device among the detected at least one device, and connecting with the highest-priority BLUETOOTH device among the detected BLUETOOTH devices.
