小车相加 语音对讲功能，

分为server 端 与 client

server 可以部署在云端 或者 你想部署的地方

                break

        print("Connected to Server")

        # start threads
        receive_thread = threading.Thread(target=self.receive_server_data).start()
        self.send_data_to_server()

    def receive_server_data(self):
        while True:

                self.playing_stream.write(data)
            except:
                pass

    def send_data_to_server(self):
        while True:
            try:
                data = self.recording_stream.read(1024)
                self.s.sendall(data)
            except:
                pass


client = Client()

 

场景：

server 计划搭建在云服务器上， 树莓派 运行 client.py  我的pc 运行 client.py 然后两个端就可以对讲了，

待完善：

增加账号等安全性的东东
