问题描述
我正在尝试在我的 PC（python 服务器）和 HoloLens 2（客户端）之间创建一个 TCP 客户端/服务器程序。 HoloLens 连接到我电脑的热点 wifi。 python 服务器每 10 毫秒发送一条消息。在 HoloLens 2 端，我创建了一个 Task，它读取 python 发送的消息，将其保存在一个变量 (this.message) 中，然后打印出来。 Unity 的 Update 函数读取这个变量并打印出来。
客户端/服务器交换工作，但我得到一个奇怪的行为。 Unity 的 Update 函数有时会“阻塞”在同一个值上，当我在 Debug 模式下运行程序时看到输出：
...

Python 端：
sock = socket.socket(socket.AF_INET,socket.soCK_STREAM)
sock.bind(('',4444))
print("[SERVER TCP] Waiting connection ...")
sock.listen(1)
client_socket,address = sock.accept()
data = client_socket.recv(1024)
print(data)
print("[SERVER TCP] Connection done")
x = 0
while True:
x = x + 1
msg = f"{x}\n"
client_socket.send(msg.encode())
sys.stdout.write(msg)
time.sleep(0.01)
