In view of the requirements of data transmission among intelligent terminals in Internet of things and the problems of intelligent equipment such as communication and computing, this paper introduces Bluetooth into the data transmission process, and puts forward the intelligent terminal data transmission system based on Bluetooth. CC2540 chip is used to realize the Bluetooth transmission. This paper analyzes the Bluetooth transmission process based on the Android system, studies the principle of wireless data transmission, and realizes the data exchange among the intelligent terminal equipment, providing a new idea to improve the data transmission ability of Internet of things.
