Abstract:To realize the configuration and management of smart gateway system, the Bluetooth Low Energy(BLE) Universal Asynchronous Receiver/Transmitter(UART) is utilized to the system, adding with an extra independent BLE module. This design allows users to simply configure and manage the gateway by device-non-contact way within a proper coverage area of BLE. Thus this method will greatly facilitate the gateway's management of startup and reset, and bring it great practicability and convenience.
