Analysis Of Bluetooth Protocols And Applications In Massage Device And WeChat Platform

With the development of society and the progress of technology,especially the birth of Bluetooth Low Energy(BLE),more and more smart home with small and low power consumption appliances has come into the market.And massage,a traditional way of regimen,has been developed to be more intelligent and miniaturized.In this study,BLE technology is applied to design a Wechat Bluetooth massage device.The WeChat Bluetooth massage apparatus adopts micro current generating module to generate various bionic micro currents,which provide benign physical stimulation and weak current oscillation stimulation on the surface of human skin,so as to achieve different massage effects.In the thesis,the current situation,characteristics and applications of Bluetooth technology were analyzed,the complete framework and protocol stack of Low Power Bluetooth was studied,and the overall design of WeChat Bluetooth massage apparatus based on this was realized.In the thesis,the hardware design of WeChat Bluetooth massage instrument,and the software realization of the connection between WeChat APP and Bluetooth,and of WeChat's control of the hardware of the Bluetooth massage instrument were mainly completed.Hardware design included the micro current generating module,battery module and RF module;micro current generating module generated all kinds of biomimetic current during massage,the battery module consisted of lithium battery charging circuit,supplying the system with power,and the RF module was composed of a ceramic antenna,sending and receiving Bluetooth signals.The software system included section of WeChat and the equipment.The section of WeChat mainly relied on the official test account and server.For the software part of this paper,mainly,the design and compilation of the software of the WeChat Bluetooth massage apparatus was completed,which included equipment development board software and equipment server software.The device development board software mainly implemented the links between WeChat and Bluetooth and the control of the massage instrument,and the device server completed the processing on the received WeChat events,text messages and so on.The software performed in accordance with the low-power Bluetooth specification requirements,and had a very strong transplantability.At the end of the thesis,the WeChat Bluetooth massage instrument is tested.Through hardware and software online debugging and oscillograph waveform,it is demonstrated that WeChat account can have a good control of the various modes and intensity changes of massage.For different massage modes,the frequency of the waveform is different,while for the same massage mode,the different intensity is reflected in the amplitude change.
