7 Data reporting communication protocol

7.1 Protocol analysis instructions

There are multiple push methods such as UDP/TCP/MQTT/HTTP. Users need to provide the public IP address and port number of the cloud server to receive data.

Example of a data message in JSON format:

{"T":27.8,"H":67.1,"ID":"860344048491162"}

Message analysis:

{

"T" : 32.1 , //temperature

"H" : .64.8 , //Humidity

"ID" : "860344048491162" //Device ID

}

7.2 Protocol reception test

The network debugging assistant NetAssist can be used to perform reception tests.

 

7.3 Protocol customization

If you need to customize other communication protocols, please contact our sales staff.

8 Platform docking

8.1 Default Platform

The product is connected to our company's designated open industrial Internet of Things platform by default when it leaves the factory. The platform interface is as follows:



Computer browser interface



WeChat access interface on mobile phone

8.2 User-specified platform

Taking the Alibaba Cloud platform docking as an example, after the user creates a product and adds a device on the Alibaba Cloud IoT platform, the user needs to provide a triple: {ProductKey, DeviceName, DeviceSecret} and the MQTT topic to be published.

For example, the values of the triples are:

ProductKey = b0FMK1Ga5cp

DeviceName = 862991419835241

DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q

Taking OneNet platform docking as an example, after users create products and add devices on China Mobile's OneNet platform, they need to provide the product ID and device registration code.

For example:

ID:332590

Registration code: DGRUa7Vr9KYGunwJ

9 Precautions

1）When the device is installed inside a metal distribution box, an external antenna should be used and the antenna should be printed on the outside of the distribution box.

2）This product has a built-in SIM card, and the annual traffic fee is about 10~20 yuan depending on the frequency of data reporting. You can also use your own SIM card, which needs to be confirmed in advance.
