I explored on sending data from Device to Cloud using Azure REST Apis. It is working seamlessly without any issues. I'm not finding good articles on sending Cloud-to-Device messages to Arduino board using "Azure IoT Hub REST Apis". Could some one provide suggestions on this

推荐答案

您也可以在Azure门户执行请求时发送请求.来自AZ Portal的所有C2D都通过此终结点发送 https://main.iothub .ext.azure.com/api/Service/SendMessage/，有效负载是一个看起来像这样的json:

You could also send the request as the azure portal does it. All C2D from AZ Portal are sent through this Endpoint https://main.iothub.ext.azure.com/api/Service/SendMessage/ and the payload is a json that look like this:

{
  "hostName": "iothub-hostname",
  "owner": "twinUpdate",
  "key": "key for the iothub",
  "deviceID": "your device on that hub",
  "body": "{\"test\": \"This is a test over postman\"}",
  "properties": "[]"
}

请记住，您需要添加带有有效Bearer令牌的授权标头.登录到AZ Portal时可以获取此信息.

Keep in mind that you need to add an Authorization Header with valid Bearer token. You can get this when you log in to AZ Portal.
