Intro
this program demonstrates how to use TCP on the Murata Wifi chip. It will connect to a server and send a message, the server will then send a reply. The reply will be printed out to the terminal on the microcontroller.
Instructions
- Make sure you have both the wifi device and the computer running the server on the same network / wifi router.
- Change the hard coded IP in the microcontroller code to match that of the laptop running the python server.
- Run the python2 script below on the computer
- Have a console hooked up to the microcontroller and watch as messages are sent back and forth between the server (python) and the client (murata).
- Run the microcontroller code on the device.
For ease of use numbers have been appended to the end of the messages being sent back and forth.
Python Server
Please run this python2.7 code on your computer. Make sure to change the IP Address in the microcontroller code to match the IP of your computer.
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('', 7))
s.listen(1)
x = 0
while True:
conn, addr = s.accept()
print 'Connected b'TCP data from server: 'y', addr
while True:
# receive data from board
data = conn.recv(1024)
# check received data
if not data:
break
# print received data
print("TCP data from microcontroller: '"+data+"'")
# send data to board with counter to differentiate messages
conn.sendall("HelloFromPython!: "+str(x)+"\n\r")
x+=1
# close the port
conn.close()
