tencent cloud

Feature Overview

A gateway device can connect and disconnect subdevices under it through the data communication with the cloud. This feature uses the same topics as those used in gateway subdevice topology management:

• Data upstream topic (for publishing): $gateway/operation/${productid}/${devicename}
• Data downstream topic (for subscribing): $gateway/operation/result/${productid}/${devicename}

Proxied subdevice connection

The gateway device can connect the subdevice to the platform through the data upstream topic. After the request succeeds, the platform will return the connection information of the subdevice through the data downstream topic.

Data format of the proxied subdevice connection request:

{
"type": "online",
"payload": {
  "devices": [
    {
      "product_id": "CFCSQ5EAG7",
      "device_name": "onlinedev00"
    }
  ]
}
}

Data format of the proxied subdevice connection response:

{
"type": "online",
"payload": {
  "devices": [
    {
      "product_id": "CFCSQ5EAG7",
      "device_name": "onlinedev00",
"result":0
    }
  ]
}
}

Proxied subdevice disconnection

The gateway device can disconnect the subdevice from the platform through the data upstream topic. After the request succeeds, the platform will return the disconnection success information of the subdevice through the data downstream topic.

Data format of the proxied subdevice disconnection request:

{
"type": "offline",
"payload": {
  "devices": [
    {
      "product_id": "CFCSQ5EAG7",
      "device_name": "offlinedev00"
    }
  ]
}
}

Data format of the proxied subdevice disconnection response:

{
"type": "offline",
"payload": {
  "devices": [
    {
      "product_id": "CFCSQ5EAG7",
      "device_name": "offlinedev00",
"result":-1
    }
  ]
}
