将数据从Unity发送到Raspberry

本文关键字：Raspberry Unity 数据 | 更新日期: 2023-09-27 18:01:22

我正试图将数据从Unity发送到树莓派。我已成功连接，但无法传递任何数据，请帮助。

这是我在树莓端使用的代码

import socket

backlog=1
size = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("169.254.242.100",50001))
s.listen(backlog)
try:
    print ( "is waiting")
    client, address = s.accept()
    while 1:
        data = client.recv(size)
        if data:
            tabela = data
            print ( "sends data")
            print (tabela[0])
            client.send(data)
except:
    print("closing socket")
    client.close()
    s.close()

这个是我在Unity中使用的

using UnityEngine;
using System.Collections;
using System.Net.Sockets;
public class UnityToRaspberry : MonoBehaviour {
public string IP = "169.254.242.100"; //
public int Port = 50001;
public byte[] dane = System.Text.Encoding.ASCII.GetBytes("Hello");
public Socket client;
void Start(){
    //dane [0] = 1;
    client = new Socket (AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    client.Connect (IP, Port);
    if (client.Connected) {
        Debug.Log ("Connected");
    }
    client.Send (dane);
}
void OnApplicationQuit(){
    client.Close();
}

}

谢谢!

将数据从Unity发送到Raspberry

我打赌你已经非常接近了!我使用了你的代码加上Unity答案[1]中的一个例子。这就是我必须通过tcp套接字在Mac OSX Sierra上的Unity 5.5.0f3和Raspberry Pi 3 Model B之间建立连接和传输数据的方法。

在统一

: 

void    setupSocket()
{
    s.socketReady = false;
    s.host = "192.20.20.2";
    s.port = 50001;
    try {                
        s.socket = new TcpClient(s.host, s.port);
        s.stream = s.socket.GetStream();
        s.writer = new StreamWriter(s.stream);
        s.reader = new StreamReader(s.stream);
        s.socketReady = true;
    }
    catch (Exception e) {
        Debug.Log("Socket error:" + e);
    }
}
void Update()
{
   s.writer.Write("Hello Pi!");
   s.writer.Flush();
}

Python on the Pi:

import socket
backlog = 1
size = 1024
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('192.20.20.2', 50001))
s.listen(backlog)
try:
    print ("is waiting")
    client, address = s.accept()
    while 1:
        data = client.recv(size)
        if data:
            print (data)
except:
    print("closing socket")
    client.close()
    s.close()
