This paper presents a design of gateway system with ARM processor as the core based on LTE and ULP network to overcome the heterogeneous barrier between mobile communication and ULP Bluetooth network. ARM9 based control panel was used as the gateway control, which was connected to the EM3760 of LTE and ULP chip CC2540 through the serial port. The periphery circuit of the chip was designed, and μC/OS-II operating system was transplanted in the main control chip to realize data frame protocol conversion. The test result indicated that the gateway realized data protocol conversion between ULP and LTE and had satisfactory performance in practical applications in HDP well.
