LuatOS/module/Air8000/demo/gnss/exgnss/single/readme.md

演示功能概述

使用Air8000整机开发板，本示例主要是展示exgnss库的三种应用模式，

exgnss.DEFAULT模式

exgnss.TIMERORSUC模式

exgnss.TIMER模式

主要操作为：

打开三种应用模式

等待40秒关闭操作TIMER模式

然后查询三种应用模式是否处于激活模式

等待10秒关闭全部应用模式，再次查询三种模式是否处于激活模式

然后获取最后一次的定位经纬度数据打印

定位成功之后使用exgnss库获取gnss的rmc数据

演示硬件环境

1、Air8000整机开发板一块

2、TYPE-C USB数据线一根

3、gnss天线一根

4、Air8000整机开发板和数据线的硬件接线方式为

• Air8000整机开发板通过TYPE-C USB口供电；（整机开发板的拨钮开关拨到USB供电）

• TYPE-C USB数据线直接插到核心板的TYPE-C USB座子，另外一端连接电脑USB口；

演示软件环境

1、Luatools下载调试工具

2、Air8000 V2010版本固件

演示核心步骤

1、搭建好硬件环境

2、通过Luatools将demo与固件烧录到核心板中

3、烧录好后，板子开机将会在Luatools上看到如下打印：
