[Abstract]:Low-power Bluetooth 4.0 technology and protocol has been proposed since 2010, because of its low power consumption, fast connection speed, high security, With the development of Bluetooth 4.0 on Android4.3 platform in July 2013, Bluetooth 4.0 technology is facing an excellent development opportunity. Based on the increasingly mature Bluetooth 4.0 technology and the rapid development of Android mobile terminal, this paper presents the concept of mobile micronetwork system and the architecture of Bluetooth 4.0 protocol stack. The implementation of Bluetooth 4.0 connection and communication and the design of Android application program are studied and described. This paper first describes the protocol stack structure of low power Bluetooth 4.0 protocol, the principle and function of each layer. The principle and key technologies of low power consumption are analyzed, and the main functions and steps of Bluetooth 4.0 programming in Android mobile terminal are introduced in detail. Then, the Bluetooth 4.0 communication module based on CC2540 chip is designed. The event-driven mechanism of OSAL system is used to handle Bluetooth 4.0 protocol stack events. The connection and communication between low-power Bluetooth device and Android mobile terminal are realized by programming. According to the actual requirements, the low-power Bluetooth anti-loss device and the Android client application of wireless sphygmomanometer are designed and implemented. Finally, the design of inverted F antenna, a 2.4GHz Bluetooth antenna used in Bluetooth communication module, is introduced. The simulation results and practical application results show that the antenna can fully cover the Bluetooth operating frequency band and has good radiation characteristics. The mobile microgrid system proposed and designed in this paper can effectively realize the connection and communication between the low-power Bluetooth device and the Android mobile terminal, and the Bluetooth anti-loss device and the wireless sphygmomanometer can realize the functions of anti-loss and health detection within the range of Bluetooth operation. This further shows that the research and development of this paper has a certain value and application prospects.
