You can use the WiFi working example available in the STM32Cube L4 FW package in Projects/B-L4S5I-IOT01/applications/WiFi.
In this example, you will use Es_WiFi module and a web Browser to create a simple Web server.

This is the example I’m following. I basically have the same thing except for saving to flash. In addition I’m using a random value instead of using the temperature sensor to get the temperature.
Other than that, I am following the working example.
The code runs into issues inside the es_wifi_io.c which I have not modified.
