from wifi import radio
from socketpool import SocketPool

from time import sleep
from secrets import secrets

radio.connect(secrets['SSID'], secrets['PASSWD'])

while not radio.connected:
    print("Connecting...")
    sleep(1)

print(f"Connected at address: {radio.ipv4_address}")

socket = SocketPool(radio)


def send_file(conn, filename, content_type):
    with open(filename, "r") as f:
        f_content = f.read()
        conn.sendall(b"HTTP/1.1 200\nContent-Type: ")
        conn.sendall(content_type.encode("utf-8"))
        conn.sendall(b"\n\n")
        conn.sendall(f_content)


with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
    s.bind(("0.0.0.0", 6969))
    s.listen(100)
    print("Listening...")

    paths = {
            "/": ("index.html", "text/html"),
            "/index.html": ("index.html", "text/html"),
            "/index.js": ("index.js", "application/javascript"),
    }

    while True:
        assert radio.connected
        conn, addr = s.accept()
        with conn:
            print(f"Connected by {addr}")
            data = bytearray([0x00]*1024)
            print(conn.recv_into(data))
            path = data.decode("utf-8").split()[1]
            print(path)
            if path in paths:
                send_file(conn, *paths[path])

Behavior

code.py output:
Connected at address: xxx.xxx.xxx.xxx
Listening...

The code hangs here as if no request are made even when they are.

Description

• Sockets stop working without any error after some soft reboot (this includes auto-reload)
• After a hard reset it works fine until it breaks again from where only a hard reset can fix the issue.

Additional information

The error doesn't happen on every single soft reboot, only randomly.
