1.4 依赖
Ota功能需要fal软件包 [ ] fal: Flash Abstraction Layer implement. Manage flash device and partition. ---> Tls功能需要mbedtls软件包 [ ] mbedtls: An portable and flexible SSL/TLS library ----
2 如何打开软件包
menuconfig配置
- RT-Thread env开发工具中使用
menuconfig
软件包,配置产品及设备信息, 路径如下:
RT-Thread online packages --->
IoT - internet of things --->

- 选项说明
Ucloud Device Config
:填写当前设备认证要素,当认证模式为动态认证时,设备密钥可以不填写
Enable Mqtt Link uiot-core Platform
:使能MQTT连接云平台功能。
Enable Ucloud Mqtt Sample
:使能静态注册mqtt和注册成功后收发消息的案例
Enable Ucloud Mqtt Dynamic Auth Sample
: 使能动态注册mqtt和注册成功后收发消息的案例
Enable Http Link uiot-core Platform
:使能HTTP连接云平台功能,包括使用https上传消息和上传文件,只支持https,勾选会关联选中mbedTLS软件包。
Enable Ucloud Http Publish Sample
:使能使用https向云平台上传消息的案例
Enable Ucloud Http Upload File Sample

- 使用
pkgs --update
命令下载需要使用的软件包
2.2 编译及运行
-
使用命令 scons --target=xxx 输出对应的工程,编译
-
打开生成的工程,编译下载到设备中
2.4 运行demo程序
系统启动后,在 MSH 中使用命令执行,以mqtt_sample为例: 启动案例:mqtt_test_example start 终止案例:mqtt_test_example stop
执行输出:
msh />mqtt_test_example start
establish tcp connection with server(host='mqtt-cn-sh2.iot.ucloud.cn', port=[1883])
msh />success to establish tcp, fd=4
