摘要
本设计利用现在已普及的智能手机为载体,设计了一款基于Android平台和低功耗蓝牙技术的智能防丢器。防丢器由两部分组成,一部分是与物件绑定在一起的从机,一部分是用户所持有的主机。当从机和主机建立蓝牙连接以后,防丢系统便正式开始运行。从机部分采用支持蓝牙4.0BLE的CC2540芯片,主机部分是常见的Android手机。在安卓系统上完成对检测软件的编程。该软件能够通过手机与蓝牙芯片之间的信号强度值来进行报警。文章阐述了Android蓝牙连接的一些细节并对判断逻辑的实现做出解释。
The design uses the smart phone as the carrier and designed an intelligent anti-lost device based on Android platform and low-energy Bluetooth technology. Anti-lost device consists of two parts, one part is the Peripheral bounded with the object. Another part is the Central held by the users.When the Peripheral and the Central establish a Bluetooth connection, the anti-lost system will officially start running.The Peripheral part is designed to support the Bluetooth 4.0 BLE CC2540 chip.The Central part of the design uses the common Android phone. In the Android system, we complete the software programming. The software can start alarm if signal strength between phone and the Bluetooth chip is out of range. The article explains some of the details of Android Bluetooth connection and explains the implementation of the judgment logic.
