iOS 网络状态监测。网络实时检测，用到Reachability（自行下载）,需加框架:SystemConfiguration.framework ios程序需要用到网络检测，有些程序是刚启动时检测一次，而有些则从头到尾检测网络状态。(IOS network status monitoring.Real-time detection and Reachability (download), frame: SystemConfiguration.framework IOS programs need to use network detection, some detection once when the program is launched, while others detect the network status start to finish.)

cc2500的头文件。寄存器的设置使得传输速率为芯片的最大值250kbps，可支持6通道1k的采样率。(cc2500 header file. Register settings for the chip transfer rate makes the maximum 250kbps, can support 6-channel sampling rate of 1k.)
