LuatOS/module/Air780EHM_Air780EHV_Air780EGH/demo/gnss

演示功能概述

使用Air780GH核心板，通过gnss.lua扩展库，开启GNSS定位，展示模块的三种功耗模式：正常模式，低功耗模式，PSM+模式

演示硬件环境

1、Air780EGH核心板一块

2、TYPE-C USB数据线一根

3、gnss天线一根

4、Air780EGH核心板和数据线的硬件接线方式为

• Air780EGH核心板通过TYPE-C USB口供电；（核心板USB旁边的开关拨到on一端）

• 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、Air780EGH 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：
