提供了订阅、发布、连接三个节点,在MQTT Broker节点填入三元组(设备ID、设备名称、设备密钥)即可连接腾讯云IoT Explorer,支持多设备发布与订阅
创建与腾讯云IoT Explorer的连接,对于同一设备的订阅和发布,可以复用同一连接。
通过节点连接腾讯云IOT Explorer,订阅topic,输出下发的内容
使用该节点前,需要先选择一个MQTT Broker
以建立链接,多个(订阅和发布)节点可共享同一连接
MQTT Broker
连接输出一个msg对象,包含topic和payload两个属性
使用Tencent IoT Subscribe节点,连接debug节点,当收到消息时,输出内容到debug面板和控制台。

通过节点连接腾讯云IOT Explorer,向设备publish内容
使用该节点前,需要先选择一个MQTT Broker
以建立链接,多个(订阅和发布)节点可共享同一连接
MQTT Broker
连接payload:上报的内容,类型为json对象
topic:publish的主题,类型string。 可以通过input来传递topic,也可以通过设置public结点的属性来指定topic,input的中topic的优先级大于节点属性
例-属性上报,payload需要包含method与params属性
msg.topic = $thing/up/property/${productID}/${deviceName}
msg.payload = {
// 上报为report
method: "report",
// 物模型
params: {
key1:"value1",
key2:"value2"
}
}
输出msg对象,包含topic和payload两个属性
使用inject节点传递数据给Tencent IoT Publish节点,然后向云端上报数据,可在腾讯云IoT Explorer看到上报的结果,上报成功后,将结果向后透传
