Send UDP packet after bind - pacmyc - Mar-11-2021
I want to send a UDP packet to 192.168.0.155 and then listen for replies on the same port as I sent the packet from.
The below code doesn't work. I can't invoke s.sendto after I have binded the socket.
Any suggestions?
import socket
import sys
ip = "127.0.0.1"
port = 42134
# Create a UDP socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# Bind the socket to the port
server_address = (ip, port)
s.bind(server_address)
print("Do Ctrl+c to exit the program !!")
send_data = 'B:reglistener'
s.sendto(send_data.encode('utf-8'), ("192.168.0.155", 42314))
while True:
print("####### Server is listening #######")
data, address = s.recvfrom(4096)
print("\n\n 2. Server received: ", data.decode('utf-8'), "\n\n")
send_data = input("Type some text to send => ")
s.sendto(send_data.encode('utf-8'), address)
print("\n\n 1. Server sent : ", send_data,"\n\n")
