ConnectionRefusedError: [Errno 111] 连接被拒绝 empatica e4

Question

我一直在尝试构建一个 python 客户端，它从 Empatica E4 收集实时数据流并能够操作数据。

from e4client import E4StreamingClient, E4DataStreamID
import threading

with E4StreamingClient('127.0.0.1', 28000) as client:
    dev_list = client.list_connected_devices()

    with client.connect_to_device(dev_list[0]) as conn:
        # connected to the first device here
        
        event = threading.Event()
    
        def _callback(stream: E4DataStreamID, timestamp: float, *data):
            print(stream, timestamp, *data)
            event.set()


        conn.subscribe_to_stream(E4DataStreamID.TAG, _callback)
        
        # block and wait for a tag press:
        event.wait()

    # device disconnected here, no need to disconnect or unsubscribe,
    # all is handled by the context manager. 

我正在尝试这个示例 python 客户端，但它一直在我这边返回错误，说连接太多。我正在使用流媒体服务器上写的端口和 ip 地址。

如果有效，应该有多个数据流入 python 客户端。
