raspberry pi 上的 TCP 服务器未连接到 android raspberry pi 上的 tcp 客户端

Question

我正在 raspberry pi 上创建一个 TCP 服务器，以便我可以通过 WIFI 从我的 android phone 控制它。我已将 pi 和 phone 连接到我的 WIFI 路由器。

import socket
from cookieLED_FINAL import callLED

host = '192.168.100.100'
port = 5560

def setupServer():
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    print("Socket created.")
    try:
        s.bind((host, port))
    except socket.error as msg:
        print(msg)
    print("Socket bind complete.")
    return s

def setupConnection():
    s.listen(1) # Allows one connection at a time.
    conn, address = s.accept()
    print("Connected to: " + address[0] + ":" + str(address[1]))
    return conn

def storeFile(filePath):
    picFile = open(filePath, 'wb')
    print("Opened the file.")
    pic = conn.recv(1024)
    while pic:
        print("Receiving picture still.")
        picFile.write(pic)
        pic = conn.recv(1024)
    picFile.close()

def dataTransfer(conn):
    # A big loop that sends/receives data until told not to.
    while True:
        # Receive the data
        data = conn.recv(1024) # receive the data
        data = data.decode('utf-8')
        # Split the data such that you separate the command
        # from the rest of the data.
        dataMessage = data.split(' ', 1)
        command = dataMessage[0]
        if command == 'GET':
            reply = GET()
        elif command == 'REPEAT':
            reply = REPEAT(dataMessage)
        elif command == 'STORE':
            print("Store command received. Time to save a picture")
            storeFile(dataMessage[1])
            print("FINISHED STORING FILE")
            break
        elif command == 'LED_ON':
            callLED()
            reply = 'LED was on'
        elif command == 'EXIT':
            print("Our client has left us :(")
            break
        elif command == 'KILL':
            print("Our server is shutting down.")
            s.close()
            break
        else:
            reply = 'Unknown Command'
        # Send the reply back to the client
        conn.sendall(str.encode(reply))
        print("Data has been sent!")
    conn.close()


s = setupServer()

while True:
    try:
        conn = setupConnection()
        dataTransfer(conn)
    except:
        break

使用IP时：

192.168.100.100 :

[Errno 99] Cannot assign requested address

127.162.100.100 或 0.0.0.0：正在创建套接字，但 android 客户端未连接。

在我的 android phone 上，我正在使用一个名为 TCP/UDP 测试工具的应用程序，它是我从 Play 商店下载的。

我是 linux 和 raspberry pi 3 B+ 的新手。

OS: RASPBIAN

编程语言：PYTHON3.5

Answer 1

下载名为 Advanced IP Scanner 的软件。

将所有设备连接到同一个网络，即接入点。

在 raspberry pi 打开终端并输入 ifconfig 获取 ipv4 而不是 0.0.0.0 或 127.0.0.1 另一个。

例如，如果 ip 显示为 192.168.100.144，则在 windows 的高级 IP 扫描器中输入 192.168.100.1-255 开始扫描并找到具有您的 raspberry pi 名称的 ip写在里面。现在在tcp客户端输入这些ips并连接。
