APPARATUS AND METHOD FOR RF COMMUNICATION BASED ON UART

摘要

PURPOSE: An RF communication device and a method thereof are provided to perform normal communication although an RF communication chip has trouble or RF communication environment become worse among RF communication execution in a sensor network. CONSTITUTION: The first RF communication unit(210) transceives a signal with an external RF terminal by using the first frequency. A plurality of second RF communication units(250) transceives a signal with the external RF terminal by using the different frequency except the first frequency. A transmission port of a controller(100) is connected to the first RF communication unit and a plurality of second RF communication units. A reception port of the controller comprises the first UART(Universal Asynchronous Receiver Transmitter) port which is corresponded and connected to the first RF communication unit. The reception port of the controller comprises the second UART port which is corresponded and connected to a plurality of second RF communication units.
