        print("连接 Wi-Fi...")
        wlan.connect("你的WiFi名称", "你的WiFi密码")
        while not wlan.isconnected():
            pass
    ip = wlan.ifconfig()[0]
    print("Wi-Fi 已连接，ESP32 IP 地址:", ip)
    print("请在 PC 端连接: ws://{}:8765".format(ip))
    return ip

do_connect()

# 创建并启动服务器
server = websocket_server.WebSocketServer("0.0.0.0", 8765)
server.start()
print("WebSocket 服务器已启动，等待连接...")

try:
    while True:
        # 阻塞等待一个客户端连接
        conn, addr = server.accept()
        if conn is None:
            continue   # 握手失败，继续等待

        print("客户端已连接:", addr)

        # 与该客户端通信直到断开
        try:
            while True:
                msg = conn.recv()         # 阻塞接收
                print("收到:", msg)
                conn.send(msg)            # 原样返回
        except websocket_server.WebSocketConnectionClosedException:
            print("客户端已断开:", addr)
        finally:
            conn.close()
            server.remove_client(conn)

finally:
    server.stop()
