Raspberry Pie Network Socket (Python edition) __python

I used the socket on my computer to communicate between two programs, and this time we used the same program to communicate between the raspberry and the computer.

First look at the program, the specific interpretation of the program can see my last blog

This time the only difference is the host to 192.168 or something, their own in the DOS interface knock ipconfig check the IP address and fill in

Server End:

Import socket
Import time

HOST = ' 192.168.199.131 '
PORT = 8001
sock = Socket.socket (socket.af_inet, Socket. SOCK_STREAM)  
Sock.bind ((HOST, PORT)  
Sock.listen (5) while  
True:  
    connection,address = sock.accept ()  
    Try:  
        connection.settimeout (  
        buf = CONNECTION.RECV (1024)  
        if buf:  
            connection.send ( B ' Welcome to server! ')
            Print (' Connection success! ')
        else:  
            connection.send (b ' please go out! ')  
    Except Socket.timeout:  
        print (' Time Out ')
    Connection.close ()  

Client side:

Import socket
Import time

HOST = ' 192.168.199.131 '
PORT = 8002
sock = Socket.socket (socket.af_inet, Socket. SOCK_STREAM)  
Sock.connect ((HOST, PORT)  
time.sleep (2)  
sock.send (b ' 1 ')
print (SOCK.RECV (1024). Decode ())
Sock.close ()  

Then run server.py in the DOS interface and run client.py in the raspberry pie.

Notice that the Python3 command is used in the raspberry pie because the raspberry pie has both python2 and Python3

DOS interface:

Raspberry pie:

If we want to run the client side on a raspberry-run server-side computer and have the raspberry sent as a server to receive user data, we can ifconfig the raspberry pie to see its address and change the IP address of the two programs to it. Then run the server on the raspberry pie and run the client on the computer.

If you want to implement UDP transmission, you can put my last blog's UDP code to modify the next try, because the specific I have not tried hehe
