Connecting as a client to another ESP8266 hosting Async websocket server is failing on long messages.

[Gabeki17]

I would like to receive some variable every second from one ESP8266.
Shot messages are arriving. but long ones are not. Like the below is cut and the rest is not even shown.

The code for the client is as follows:

/*

#include <Arduino.h>

#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>

#include <WebSocketsClient.h>

#include <Hash.h>

ESP8266WiFiMulti WiFiMulti;
WebSocketsClient webSocket;

void webSocketEvent(WStype_t type, uint8_t * payload, size_t length) {

switch(type) {
	case WStype_DISCONNECTED:
		Serial.printf("[WSc] Disconnected!\n");
		break;
	case WStype_CONNECTED: {
		Serial.printf("[WSc] Connected to url: %s\n", payload);

		// send message to server when Connected
		webSocket.sendTXT("Connected");
	}
		break;
	case WStype_TEXT:
		Serial.printf("[WSc] get text: %s\n", payload);

		// send message to server
		// webSocket.sendTXT("message here");
		break;
	case WStype_BIN:
		Serial.printf("[WSc] get binary length: %u\n", length);
		hexdump(payload, length);

		// send data to server
		// webSocket.sendBIN(payload, length);
		break;
    case WStype_PING:
        // pong will be send automatically
        Serial.printf("[WSc] get ping\n");
        break;
    case WStype_PONG:
        // answer to a ping we send
        Serial.printf("[WSc] get pong\n");
        break;
}

}

void setup() {
// Serial.begin(921600);
Serial.begin(115200);

//Serial.setDebugOutput(true);
Serial.setDebugOutput(true);

Serial.println();
Serial.println();
Serial.println();

for(uint8_t t = 4; t > 0; t--) {
	Serial.printf("[SETUP] BOOT WAIT %d...\n", t);
	Serial.flush();
	delay(1000);
}

WiFiMulti.addAP("Balicsa", "326534qwA");

//WiFi.disconnect();
while(WiFiMulti.run() != WL_CONNECTED) {
	delay(100);
}

// server address, port and URL
webSocket.begin("192.168.11.99", 80, "/ws");

// event handler
webSocket.onEvent(webSocketEvent);

// use HTTP Basic Authorization this is optional remove if not needed
webSocket.setAuthorization("user", "Password");

// try ever 5000 again if connection has failed
webSocket.setReconnectInterval(5000);

// start heartbeat (optional)
// ping server every 15000 ms
// expect pong from server within 3000 ms
// consider connection disconnected if pong is not received 2 times
webSocket.enableHeartbeat(15000, 3000, 2);

}

void loop() {
webSocket.loop();
}

I will answer may own question as follows:

I did not have a full understanding on the logic of fregmentation.

So the key was this section in the websocketEvent section:

WStype_FRAGMENT_BIN_START, WStype_FRAGMENT, WStype_FRAGMENT_FIN,
