According to another embodiment, if a characteristic is found, a callback function can be called. Specifically, if a connection request is made to the peripheral in the first monitoring application, data can be transmitted by the next callback function.

Also, the function to check whether data transmission is successful is as follows.

According to one embodiment, the processor 330 may control the communication unit 310 to transmit an identified service control signal to the device of the protection target. The service control signal includes an alert control signal for controlling the device of the person to be protected to sound an alert, a control signal for attempting telephone connection from the device of the person to be protected to the device 110 of the person to be protected, And a control signal for transmitting the position of the control signal.
