[android] jni DL : 0: 在以前的文章中，我已經表明，它可以連接一個藍牙模塊到ATMEGA微控制器通過 UART串行接口，甚至進一步，發現它使用藍牙功能的電腦或智能手機。 9600串行鏈路的建立，可以比用來交換數據。使用Android手機用於此目的也不例外。我將用它來控制英仙座3機器人平台。我米做的是直接連接的Android與 ATMEGA單片機通過串口藍牙連接。所以，你可以使用這種技術用於其他目的不是機器人，因為 ATMEGA有一個大範圍可能的用途：控制光在家裡使用的Android手機，閱讀各種傳感器和收集數據的Android等。-In a previous article, I ve shown that it is possible to connect a bluetooth module to an ATMega micro controller via the UART serial interface and even further, discover it using a bluetooth enabled computer or smartphone. The 9600bps serial link established, can than be used to exchange data. Using an Android phone for this purpose is no exception. I will use it to control the Perseus 3 robot platform. What I m doing is directly interfacing the Android with the ATMega microcontroller via the serial bluetooth link. So you can use this technology for other purposes than robots, since the ATMega has a large range of possible uses: control the light in your home using the Android phone, read various sensors and gather the data on the Android, and more.
