Help with Websocket Server

[AresXT]

Hi i am using Esp32 as websocket server using ESPasynchronus webserver . I need help with the disconnection part .

#include <Arduino.h>
#include <WiFi.h>
#include <ESPAsyncWebServer.h>
// #include <ESPAsyncTCP.h> // For ESP8266

#define WIFI_SSID "SSID"
#define WIFI_PASSWORD "PASS"

AsyncWebServer server(80);

// Set up WebSocket
AsyncWebSocket ws("/ws");

IPAddress local_IP(192, 168, 1, 64);
IPAddress gateway(192, 168, 1, 1);
IPAddress subnet(255, 255, 255, 0);
IPAddress primaryDNS(192, 168, 1, 1);
IPAddress secondaryDNS(8, 8, 4, 4);

void setup() {
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS);
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  while (WiFi.status() != WL_CONNECTED) { delay(100); }
  Serial.print("WiFi connected, IP: ");
  Serial.println(WiFi.localIP());

  server.begin();

  // Set up WebSocket
  ws.onEvent(onEvent);
  server.addHandler(&ws);
}

void loop() {
  ws.cleanupClients();
}

void onEvent(AsyncWebSocket *server, AsyncWebSocketClient *client, AwsEventType type, void *arg, uint8_t *data, size_t len) {
  switch (type) {
    case WS_EVT_CONNECT:
      Serial.printf("WebSocket client #%u connected from %s\n", client->id(), client->remoteIP().toString().c_str());
      break;
    case WS_EVT_DISCONNECT:
      Serial.printf("WebSocket client #%u disconnected\n", client->id());
      break;
    case WS_EVT_DATA:
      handleWebSocketMessage(arg, data, len);
      break;
    case WS_EVT_PONG:
      Serial.printf("WebSocket client #%u ponged\n", client->id());
      break;
    case WS_EVT_ERROR:
      Serial.printf("WebSocket client #%u error(%u): %s\n", client->id(), *((uint16_t *)arg), (char *)data);
      break;
  }
}

void handleWebSocketMessage(void *arg, uint8_t *data, size_t len) {
  AwsFrameInfo *info = (AwsFrameInfo *)arg;
  if (info->final && info->index == 0 && info->len == len && info->opcode == WS_TEXT) {
    data[len] = 0;
    String message = (char *)data;
    Serial.println(" ");
    // Handle WebSocket message
    Serial.print("Recieved Message:");
    Serial.println(message);
  }
}

In the Disconnect part

case WS_EVT_DISCONNECT:
      Serial.printf("WebSocket client #%u disconnected\n", client->id());
      break;

When a client connect and disconnect it is displayed fine .But when a client disconnects due to power loss or any other reason (couldnt send closing frame to server) .When the device connects again it is treated as second client .So what should i do to disconnect the first client .

Run this periodically

ws.cleanupClients();

[AresXT]

i am using it in the loop but not solving the issue

[racpi]

what issue ?
ws.cleanupClients();
cleans up all disconnected clients and releases any resources so held when it's run

[AresXT]

I don't know when i connect the server using client (esp8266) by resetting nodemu it is only adding clients not removing old client

client 1 connected   //This is first connection 
client 2 connected   //This is second connection after reset of client

the client 1 does not disconnect it stays like that even after

@racpi

ws.cleanupClients();
