Hi @MirkoGelsomini

PROBLEM: Immediate disconnection after connection

That's the way the example is written and you have to read and understand to use

WebSockets2_Generic/examples/Generic/RP2040W/RP2040W_ServerAllFunctionsDemo/RP2040W_ServerAllFunctionsDemo.ino

Lines 153 to 157 in aa30bc0

// close the connection
client->close();
}
delete client;

You must modify the example depending on your different use-case.

You have to write the correct and matching WS Client to reconnect in loop to use with this example.

For example, the WS server is @ 192.168.2.118:8080

Python WS Client code WSClient.py

# Run by $ python3.8 WSClient.py
# From websocket-client package. Install by $ pip3 install websocket-client
import websocket
import time

ws = websocket.WebSocket()

while True:
    ws.connect("ws://192.168.2.118:8080")
    ws.send("Hello, Server")
    result = ws.recv()
    print(result)
    time.sleep(10)

WS Client Terminal

FYI, I just add WSClient_Python example to be used with the WS Server examples

from websockets2_generic.
