Full Discussion: Arduino Project with NB-IoT (3GPP) and LoRa / LoRaWAN

According to the NB-IoT Arduino device (library) I just ordered, after it is registered with AIS (the service provider), we can send UDP messages to any server we choose; so while waiting for this device to arrive, here is the test code I will use on a server:



Code:
python$ cat test_nbiot.py

"""
NB-IoT First Test Code
Listens on a port for UDP, simple authentication, echo back with unix time
Neo www.unix.com  1 Jan 2020 
Use and modify as you like.  
"""
import socket
import sys
import time

# Create a TCP/IP socket
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
port = 33313
# Bind the socket to the port
server_address = ('www.mytestserver.com', port)
print >>sys.stderr, 'starting up on %s port %s' % server_address
sock.bind(server_address)
password = "my_cool_password\n"
authenticated = False
receivepw = False

while True:
    print >>sys.stderr, '\nwaiting to receive message'
    data, address = sock.recvfrom(4096)

    print >>sys.stderr, 'received %s bytes from %s' % (len(data), address)
    print >>sys.stderr, data

    if data:
        if authenticated == False and receivepw == False:
            sent = sock.sendto("Password:\n", address)
            receivepw = True
        elif receivepw == True and authenticated == False:
            if data == password:
                sent = sock.sendto("Authenticated\n", address)
                authenticated = True
            else:
                sent = sock.sendto("Password:\n", address)
        elif authenticated == True:
            received = "You sent: " + data
            sent = sock.sendto(received, address)
            data = time.time()
            data = "Unix Time: " + str(data)+"\n"
            sent = sock.sendto(data, address)
        else:
            sent = sock.sendto("Error\n", address)

        print >>sys.stderr, 'sent %s bytes back to %s' % (sent, address)

So, after I get that simple python code working with the incoming NB-IoT Arduino shield in the mail, will be time to start prototyping on the board.
