ARMony华为云IoT应用开发-智慧井盖
华为云IoT平台产品创建
1、登录华为云file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image002.jpg
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image004.jpg
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image006.jpg
2、华为云接入协议
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image008.jpg
WIN + R键打开PC命令行CMD，执行如下命令获取接入域名的IP地址。
ping a161b173a6.iot-mqtts.cn-north-4.myhuaweicloud.com
通过ping命令可以查询到接入域名的IP地址为121.36.42.100
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image010.jpg
IP地址对应例程代码中的OC_SERVER_IP，端口号1883对于例程代码中的OC_SERVER_PORT。

file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image014.jpg
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image015.png file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image017.jpg
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image019.jpg
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image021.jpg
连接华为云前需要获取CLIENT_ID、USERNAME、PASSWORD，访问
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image023.jpg
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image025.jpg
如果实验板刚重启时未激活，并在华为云平台可以看到鉴权失败，则重置该密码，保证与编译时密码一样。

WIFI连接网络
修改例程代码 d e v i c e r o c k c h i p r k 2 2 0 6 s d k _ l i t e o s b o a r d s r c c o n f i g _ n e t w o r k . c中的W I F I _ S S I D 和
WIFI_PASSWORD为使用WIFI的SSID和密匙，用于连接网络，设备通过WIFI访问华为云。

1、修改编译脚本
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image031.png
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image033.png
2、编译固件
用cd 命令切换到路径lockzhiner-rk2206-openharmony3.0lts
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image035.jpg
Hb clean 如果之前有编译过一定要先清除之前编译文档，否则会出错
Hb set-root .
Hb set
Hb build-f 编译时一定要全编译

file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image039.jpg
3、烧写固件
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image041.jpg
弹出的对话框中，依次选择homelzdz /out/rk2206/lockzhiner-rk2206/images，选中 rk2206_db_loader.bin文件
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image043.jpg
指定fireware文件
弹出打开对话框，选择主目录下 ut/rk2206/lockzhiner-rk2206/images，选中 Firmware.img文件
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image045.jpg
Type c数据线连接电脑与小凌派开发板（插入开发板的USB-OTG（即烧录口））
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image047.jpgfile:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image049.jpg
长按maskrom，然后点按reset。直到烧写工具出现：“发现一个MASKROM设备”

file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image053.jpg
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image055.jpg
将C头拔下，插入开发板的UART（即调试串口）
file:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image057.jpgfile:///C:/Users/Anping/AppData/Local/Temp/msohtmlclip1/01/clip_image059.jpg
打开MobaXterm软件，点击Session，再点击Serial
