Device network status

Automatically report the network status to IoT Platform

The following topics are used when a device sends requests to IoT Platform and IoT Platform sends responses to the device:

Request topic: /sys/{productKey}/{deviceName}/_thing/diag/post

Response topic: /sys/{productKey}/{deviceName}/_thing/diag/post_reply

Sample request in the Alink JSON format:

• Current data: the data that is immediately reported after the data is collected by the device.

  The device immediately reports the network status data in the following two scenarios:

  • When a network error is detected, the device immediately reports the error to IoT Platform.
  • If you have set scheduled collection, the device collects data at the specified time and immediately reports the data.

  For example, the device detects a network error at 08:10:29 of August 22, 2019 and immediately reports the data. Sample request that reports data when the device detects a network error:

  {
    "id": "123",
    "version": "1.0",
    "params": {
      "p": {
        "wifi": {
          "rssi": 75,
          "snr": 20,
          "per": 10,
          "err_stats":"10,02,01;10,05,01"
        },
        "_time": 1566432629000
      },
      "model": "quantity=single|format=simple|time=now"
    }
  }

  Note If no error is detected during scheduled collection, the err_stats parameter is empty.
• Historical data: the data that is not immediately reported. In most cases, the device may delay the reporting of the collected network metrics. When the device reports historical data, the device can report multiple data records at a time.

  Sample request:

  {
    "id": "123",
    "version": "1.0",
    "params": {
      "p": [
        {
          "wifi": {
            "rssi": 75,
            "snr": 20,
            "per": 10,
            "err_stats":"10,02,01;10,05,01"
          },
          "_time": 1566432629000
        }
      ],
      "model": "format=simple|quantity=batch|time=history"
    }
  }

  Note If no error is detected, the err_stats parameter is empty.

Sample response in the Alink JSON format:

{
  "id": "123",
  "version": "1.0",
  "code": 200,
  "data": {}
}
