With the rapid development of the Internet of Things era, the types and stocks of wifi IoT products on the market are also increasing sharply. The technology of controlling wifi IoT products through network terminals is very mature.

The application scenario of wifi IoT products is usually that the mobile phone and wifi are under the same wireless local area network, and the mobile APP directly communicates with the wifi device through the network to achieve the purpose of controlling the wifi device or data transmission. Since the wifi device communicates with the cloud and mobile APP through the network, the quality of the network between them is particularly important. Especially when there may be a large amount of data or frequent data communication between the mobile APP and wifi products, if the network is not good, it is likely to cause data communication failure, which will affect the user experience. Therefore, it is necessary to obtain the network status between the mobile APP and the wifi device.

There is no network status report between the existing wifi device and the mobile APP. Usually, the APP will set a timeout period (denoted as T). If the network data is not received within T time after sending to the wifi device, it is considered to be a network error. time out. The main disadvantages of this mechanism are:

There is not always data communication between the APP and the wifi device. If there is no data communication between the APP and the device, the APP cannot judge the quality of the network.
