  • Publication number: 20210290118
    Abstract: An apparatus for controlling operations of a continuous glucose monitoring system. When a continuous glucose monitoring system is located within a certain distance from a user terminal, power of a battery is supplied to the continuous glucose monitoring system through a power switch switched on by an enable signal generated by a near field communication module, thereby operating the continuous glucose monitoring system without user intervention. The near field communication module provides connection information to the user terminal, thereby automatically performing a pairing connection with the user terminal using the near field communication module and a bluetooth communication module. When the pairing connection with the user terminal is completed, an enable signal generated by the bluetooth communication module is provided to the power switch, thereby maintaining the pairing connection with the user terminal even when the user terminal is outside of range for near field communication.
