In this paper, a lowpower IoT gateway is designed to reduce the operating power consumption and improve the versatility, which is based on Bluetooth 4.0 and IEEE 1888 protocol. The gateway is developed on the Arduino hardware platform which is integrated with Bluetooth 4.0 module and Ethernet module, and enables the sensors data from Bluetooth 4.0 device accessed. Also, it implemented bidirectional communication between the server and the gateway based on IEEE 1888 protocol. The test results show that the developed gateway has the advantages of lowpower, universality and realtime operation.
