DFROBOT WIFI Shield V3 : receive httprequest - sample code

Development Tools IDE 1.x
1

Hello
Up to now I was using an Arduino Uno Wifi to receive httrequest from a smartphone. The target is to receive commands to guide a robotic platform. Sample : httprequest sent by the smartphone : 192.168.0.99/FWD > FWD = command to move forward.

I want to replace this Arduino Uno Wifi with Dfrobot WiFi Shield

The shield seems to work, I can enter web interface and set static ip adress. But I don't find any sample code, or library for this shield. And of course the code used for the Arduino Uno Wifi is not working. I must add that I'm not an expert in this field.

Is it a bad choice and it's better to send it back to the shop or is there a solution to make it work ?

Thanks for your suggestions

This is the code used for the Arduino Uno Wifi :

#include <SoftwareSerial.h>// import the serial library
#include <stdio.h>          /* printf */
#include <stdlib.h>         /* strtol */
#include <Wire.h>          // Pour afficheur Oled
#include <ArduinoWiFi.h> 
 
char txc[20];
String readString;

void setup()
{ //======= Pour réception commandes en WIFI =============================
  Serial.begin(9600);
  Serial.println("Setup");
  Wifi.begin();  
  readString = "";
  Serial.println("Arduino Wifi Started");
}
 
void loop()
{   
  while(Wifi.available()){proc1(Wifi);}
} 

void proc1(WifiData client) {
  String command = client.readStringUntil('/');
  readString = client.readStringUntil('/');
  Serial.print("Chaîne recue : ");
  Serial.println(readString);
  client.println("Status: 200 OK\n");
}
