Teltonika TCP listner in Python

[Alex]

Hy to all, i'm writing a TCP listner in python for teltonika devices FMXXXX.
they must be accepted by the server, before send AVL packets… this is my portion of server code which..is working just to receive the imei code…and to send the ack "01", but i cannot receive any AVL data! Where am i wrong?

thanks in advace

#!/usr/bin/env python

import socket

TCP_IP = '192.168.0.1'       
TCP_PORT = 45000  
BUFFER_SIZE = 1024     
MESSAGE = '01' 

   
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)   
s.bind((TCP_IP, TCP_PORT))    
   
while 1:

    s.listen(1)
    conn, addr = s.accept()        
    print ('Connection address:', addr)     
    data = conn.recv(BUFFER_SIZE)    
    #if not data: break
    imei = data.decode("iso-8859-1")
    print ('received data:', imei )

    print ('Sending data to client…')
    msg = MESSAGE.encode('utf-8')
    conn.send(msg)
    print ('Message sended…')

i don't know java….i will learn it!  =(
my main problem is that i cannot send "01" to the device, i'm tryng to encode it in binary as described in the protocol with the command: "msg = MESSAGE.encode('utf-8')"… but nothing!
