注:lua版本需要分别下载“底层软件”和“上层软件”,并解压以备用。两个core任选一个地址下载,两个上层软件也是任选一个地址下载。

请注意 >

切勿使用2G 模块的lua代码

 


四、Luat开发入门

使用Lua进行二次开发,是Air系列模块最大的特色,具有效率高,稳定性强等有点,深受开发者的欢迎。在本章节将介绍一下如何使用Lua进行二次开发。

 

1、LuaTools简介

“工欲善其事必先利其器”,LuaTools就是开发者进行二次开发利器。使用该软件,开发者就可以轻松实现下载、调试,同时它还具有语法检测、生成量产文件等多种功能。

 

软件主界面各按钮的功能如下:

Air720 4G LTE 开发板使用说明

 

序号

名称

作用

1

UART打印口

选择连接开发板LOG口 的USB转COM口对应的端口号

2

状态窗口

显示系统状态、信号强度、底层版本类型、软件版本等信息

3

下载CORE

下载模块底层软件

4

下载Lua脚本

下载开发者代码和lib文件

5

生成量产文件

生成量产文件和远程升级文件

6

Trace输出控制

可控制是否开始打印、暂停打印、清空等

7

搜索栏

搜索Trace内容中的关键字

8

Trace打印窗口

输出用户代码的Trace和部分底层Trace

 

2、开始下载

首先,下载之前请确保模块处于关机状态(供电开关打到OFF)!

下载AT命令版本

只需要上一章提到的AT命令的底层软件即可。

第一步:运行luaTools.exe, 不要去管串口(工具会自动识别USB下载口),直接点:下载core(.blf)

 Air720 4G LTE 开发板使用说明

第二步:点浏览文件,并选择.blf文件

注:请保持底层软件目录结构完整性,切勿仅单独使用.blf文件

 Air720 4G LTE 开发板使用说明

第三步:供电开关打到ON,并长按开机键。会有下载进度条,下载完成也会有提示。

 Air720 4G LTE 开发板使用说明


下载lua版本

准备好上文提到的“底层软件”和需要下载的Lua代码(上层软件);

接下来,在主界面的“UART(打印口)”打开对应串口,以便观察下载时的Trace信息;点击【下

Lua脚本】按钮,弹出如下界面:

Air720 4G LTE 开发板使用说明

 

以下载“Luat_V0001_ASR1802底层 + 用户代码”为例:

第一步:选择底层软件文件夹中的Luat_V0001_ASR1802.blf文件(请保持底层软件目录结构完整性,切勿仅单独使用.blf文件);

第二步:选择所有需要下载的.lua文件(用户代码及所有需要用到的.lua库文件)、资源文件(如.mp3,.crt等);

第三步:点击【下载脚本】按钮;

第四步:检查文件依赖完整性,清除代码注释,软件完成初始化,;

第五步:开发者根据软件提示,将拨杆开关拨到ON,给模块上电,自动开始下载;

第六步:完成下载。

 

如果是第一次给模块下载,请选择【下载CORE+脚本】;之后直接点击【下载脚本】,这时会提示“初始化完毕,请给模块上电”。

小贴士 >

下载CORE相当于给模块“装操作系统”,下载脚本相当于给模块“安装应用软件”。所以第一次下载要先给模块“装系统”,然后“装软件”;其后模块已经有了操作系统,所以只需要“装软件”即可

 

下载前,请一定要确保模块处于关机状态;待软件提示上电后,再将供电开关拨到ON位置:

 Air720 4G LTE 开发板使用说明

模块上电后会自动和工具同步进行下载,此时请保证拨杆出于ON位置,直到下载完成:

 

3、运行用户代码

下载完成后,长按开机按键,保持开机按键不放大约4秒左右,模块会正常开机,LuaTools的Trace打印窗口窗口会打印相关内容:

 

小贴士 >

另外,模块在下载成功后也会自动开机运行新下载的lua脚本

 


五、Trace解读

模块在运行过程中,会针对不同情况输出不同的Trace内容。通过解读,开发者可以了解模块运行状态,更高效的进行调试和开发。

 

1、下载LOG

模块在和LuaTools下载工具下载同步成功后,进行下载时,Trace窗口会打印相关log:

 

 

其中,Downloading”表示开始下载,“end”表示下载结束。

下载结束之后会自动重启:

 

 

2、信号强度

模块正常运行,开发者可以观察Trace中的CSQ输出值,了解信号强度:

 

 

我们可以看出,此时信号强度值为10;开发者还可以在搜索框中输入“CSQ”,查询与信号强度有关的内容。

3、网络状态

通常,开发者可以通过观察主界面的“系统状态”提示来判断当前网络状态。

Air720 4G LTE 开发板使用说明
 

上图可以看出网络已经注册成功。

 

网络制式切换的时候会有+MODE的主动上报。开发者在Trace中搜索“NetMode”,根据后面对应的数字,判断网络制式:

上报内容

网络状态

NetMode_noNet=0

NetMode_GSM=1

2G

NetMode_EDGE=2

2.5G

NetMode_TD=3

3G

NetMode_LTE=4

4G

 

4、SIM卡

当模块出现异常(注册不上网等问题)时,可以通过主界面系统状态来判断:

Air720 4G LTE 开发板使用说明

如图所示,如果出现此提示,则证明SIM卡没有插入或者SIM卡与卡槽之间出现了松动,属于SIM卡异常。

 

如果SIM已欠费,则会如下提示:

 Air720 4G LTE 开发板使用说明

 

5、CPU

如若软件运行时发生异常,Lua代码会停止执行,输出如下信息后,模块自动重启,:

六、常见问题

1、模块无法下载

下载时,开发者可能会遇到如下问题:

 Air720 4G LTE 开发板使用说明

 

它通常是因为模块没有正确上电”,或者“USB驱动未正确安装”这两个原因造成的。

未正确上电

下载前,拨杆开关应处于OFF状态,之后再按照软件提示,将供电开关拨到“ON”状态将模块上电。

未正确安装驱动

正确安装USB驱动后,设备管理器应有如下设备:

Air720 4G LTE 开发板使用说明

如果未发现该设备,而是其他未知设备,则可以判断是没有安装驱动或者驱动安装不正确。请参考上问相关章节,安装USB驱动。

 

2、无法联网

当模块出现了无法联网的情况时,可以从以下三个方面判断:

天线问题

检查是否适用的4G天线;普通GSM天线或Wi-Fi天线无法胜任;

检查天线接口有没有松动,尝试重新插拔天线,若还是无法联网,尝试换根天线或者将辅助天线再安装上进行测试。

信号差

模块无法联网还有可能是模块所处地区信号不太好导致的,这时主界面系统状态会有“信号弱”等相关提示,可以尝试将模块换个地方进行测试。

SIM卡未插好或者已经欠费

检查一下模块的SIM卡是否插好,或者SIM卡与卡槽之间是否出现了松动,尝试拔下来重

新插一次,再进行下一步操作。(注意:也有可能是SIM卡欠费导致模块无法联网)。

 

3、Trace输出异常

当使用模块在进行开发时,经常会遇到一些问题,这时我们需要抓Trace来对问题进行分析。但偶尔也会发现抓取的Trace中没有与问题相关的。可能的原因有

内容过多

如果窗口显示过多的Trace,并且通过关键词搜索没有搜索到与问题相关的Trace,尝试修改一下代码,减少一些与问题无关的Trace打印。

接线问题

检查模块的接线是否正确(应接UART1),接线错误也有可能导致无法抓取相对应的Trace。

 

4、无法开机

当对模块进行上电后,无法进行脚本的下载,也就是模块还没有正常开机,这时候需要根据下列情况判断。

开关是否拨到“ON”位置

观察供电开关是否拨到“ON”位置。如若没有,请拨至“ON”,长按开机键4s左右将模块开机,再观察脚本是否能下载。

用户代码错误

模块无法开机,有可能是某个用户代码程序出现问题。开发者可以尝试进行语法检查,判断错误所在,再下载到模块内进行调试。
