Problem in routing on ESP's Board

[Mohammadreza-Sorouriyan]

Hi, I'm working on a project where I need to set an esp32 as an access point, and some esp8266-01 as a client.

Then i running a web server on each of the esp822 chips to get the sensor data in json format. Now I have done this, when I connect to this network with my mobile and enter the IP of one of the esp8266s, i get response but with two special esp8266.

And other esp8266's there's get ip from access point but the web server doesn't send any response and timed out. I even tried 7 type esp8266 models but it didn't work, but when I replace the access point with the home modem instead of esp32. All of esp8266 works perfectly!!

I think the esp32 can't handle and route the IP's. But here is a contradiction, why those two models of esp8266 working perfectly amd other no??

This is access point Code for ESP32

const char* ssid     = "esprouter";
const char* password = "9167997734";

void setup() {
  Serial.begin(115200);

  Serial.print("Setting AP (Access Point)…");
  WiFi.softAP(ssid, password);
}

void loop(){

}```

**And this Client code for ESP8266's**

```#include <ArduinoJson.h>
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
#include <DHT.h>
#include <WiFiUdp.h>

#define DHTPin 2 
#define DHTTYPE DHT11 
DHT dht(DHTPin, DHTTYPE);                

const char* ssid = "esprouter";  
const char* password = "9167997734"; 

ESP8266WebServer server(80);

void handle_OnConnect();
void handle_OnConnect2();
void handle_NotFound();

float Temperature;
float Humidity;

void setup() {
  Serial.begin(115200);
  dht.begin();        

  Serial.println("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
  delay(1000);
  Serial.print(".");
  } 
  Serial.println("");
  Serial.println("Connected to WiFi");
  Serial.print("IP: ");  Serial.println(WiFi.localIP());

  server.on("/info", handle_OnConnect);
  server.on("/get", handle_OnConnect2);

  server.onNotFound(handle_NotFound);
  server.begin();
  dht.begin();
}
void loop() {

  server.handleClient();

}

void handle_OnConnect() {
  DynamicJsonDocument doc(1024);
    doc["type"] = "dht-sensor" ;
    doc["id"]   = 128;
    doc["ip"]   =  WiFi.localIP().toString();
    String response;
    serializeJson(doc, response);
    server.send(200, "content/json", response);
}

void handle_OnConnect2() {

  Temperature = dht.readTemperature(); 
  Humidity = dht.readHumidity(); 
  DynamicJsonDocument doc(1024);
    doc["temp"] = Temperature;
    doc["hum"]   = Humidity;
    String response;
    serializeJson(doc, response);
  server.send(200, "content/json", response);

}

void handle_NotFound(){
  server.send(404, "text/plain", "Not found");
}```

Thanks if anyone can guide me...

SoftAP has a limit of 4 connections ... Is it possible that 4 devices were already connected?

FYI ... for code sections to look like this ...

Use the following syntax:

No. The devices connected to the AP are less than 4.

Are you cleanly disconnecting from WiFi on the client side? I did some testing ... If I connect my phone to the WiFi SoftAP, then walk away from the ESP32, it seems to take some time (about 5 minutes if I remember correctly) for the ESP32 to indicate the client count back down to zero.

If I connect my to a different WiFi network or shut off WiFi, the ESP32 indicates a zero client count right away.
