Abstract: With the development of Internet of Things, the researches on short-range wireless communications technology become more and more, but little of them are about a variety of complementary technologies. In this paper, with the comparative analysis of ZigBee and Bluetooth technology, the data frame format of information conversion between ZigBee and Bluetooth devices based on the ZigBee protocol stack is designed. The Bluetooth device is as the links and access media between ZigBee sensor network and mobile/internet. The gateway based on ZigBee and Bluetooth is designed and experimented. The experiment shows the design of ZigBee and Bluetooth connectivity is practical.
