TinyOS无线传感器网络串口通信和无线通信是怎样的

今天就跟大家聊聊有关 TinyOS无线传感器网络串口通信和无线通信是怎样的，可能很多人都不太了解，为了让大家更加了解，小编给大家总结了以下内容，希望大家根据这篇文章可以有所收获。

我作为TinyOS入门新手，在学习串口通信和无线通信时遇到不少问题。下面主要是给出一个自己写的示例程序。无线传感器节点收到其他节点的数据通过串口发送给PC，PC通过串口发送指令到节点，节点再通过无线广播PC发送的指令。

项目包含3个文件：Makefile、SerialC.nc、SerialAppC.nc。

Makefile

COMPONENT=SerialAppCinclude $(MAKERULES)

SerialAppC.nc
