天罡北斗队 北斗模块MXTOS2-200 测试报告
        天罡北斗队马道长拿到模块有一段时日了，眼看大赛之期不久将至。近日马道长率全真七子对北斗模块MXTOS2-200 做了下简单测试.现将测试之结果禀报如下:
首先按照官方文档《MXTOS2-200 使用说明》1.4版 将串口（TXD0，RXD0），电源(VCC3.3）和地（GND）及天线连接好(见模块飞线图)。在计算机上用串调试工具观察，良久未观察到输出 。众人愕然之时，邱道长指出 VCCRF 还未有连接呢.马道长使出全真教的飞针走线的招式将VCCRF与VCC3.3飞线相连，再上电，只见串口工具不断吐出如下数据，众道长喜形如色，但细察之，大家的脸色又凝重起来，五六分钟过去了，没有看到正确的定位结果，都是一些0 。此刻傻小子郭靖正好外出回来，见师傅们一筹莫展，他看了下文档《MXTOS2-200 使用说明》后指出，用有源天线馈电电压输入端ANTVCC应接3.3伏。 马道长再使一招飞线功夫将模块的第4脚ANTVCC连接到VCC3.3。再观察串口 ，大事不好，串口工具都不输出数据，电源指示灯也熄灭了，莫非模块烧坏了。大家焦灼之时，马道长说道，诸位切莫惊慌，待我断开ANTVCC与VCC3.3的连接再看看。断开后，模块恢复了，但一直没有输出正确的定位结果。全真七子的天罡北斗阵已无能为力了。请官方或有识高人回答：1、为什么不能输出正确的定位结果。2、ANTVCC到底该不该与VCC3.3连接，3、怎么控制定位模式。
