Electronic device for managing data in Bluetooth low energy (BLE) communication and method for controlling the same

According to an embodiment, an electronic device may include: a communication module comprising communication circuitry configured to operate in Bluetooth low energy (BLE), a memory, and at least one processor operatively coupled to the communication module and the memory. The at least one processor may be configured to: receive authentication information about each function from an external electronic device via BLE, the authentication information about each function including information about data for the function and information about an access right level of the function, store the received authentication information about each function in the memory, and control the communication module to transmit an authentication index of each function corresponding to the authentication information about the function to the external electronic device by BLE.
