Arduino Project: iPhone to HM-10 BLE to NB-IoT Shield to NB-IoT Network to Internet to Linux Server

Success!
Push a button on the iPhone and send a BLE bluetooth message to the Arduino UNO who forwards the request to a remote server via a commercial NB-IoT network; where the server parses the request and returns the results back to the iPhone via the same NB-IoT / BLE link.
In this case we request the load average of a remote Ubuntu Linux server 'cat /proc/loadavg' 12 times zones away. The remote server runs a Python UDP service "test app" for this "mini application" example.
BLE/NB-IOT/UDP internetworking
I think I may well be the first "maker" to do this with the Arduino UNO, and iPhone, the HM-10 BLE module and an NB-IoT shield and commercial network... but I cannot be sure!
I'm currently testing reliability. Will post the draft Arduino UNO sketch and the Python UDP test server code when finished preliminary testing. Please don't expect a polished product, as this is just a demonstration using the iPhone to send a BLE message to the Ardunio with an NB-IoT shield to forward the request to a remote UDP server and display the results back on the iPhone.
Also, I think I should include a few more "mini-app buttons" for this demo.

MULTINET(8) System Manager's Manual MULTINET(8) NAME
multinet - Connect to a Multinet* DECnet over IP server SYNOPSIS
multinet [options] <local-decnet-addr> <remote-host> DESCRIPTION
This utility creates a tapX device and copies all the DECnet packets from that over IP to a remote Multinet* server. It provides a way to connect a Linux box to a remote VMS machine over an IP-only network. Using Linux routing it should be possible to connect DECnet networks over the internet using this technique. local-decnet-addr DECnet node address of the tapX interface. This need not be the same as the address used on other interfaces but it might be less confusing if it is. remote-host IP address or host name of the remote Multinet server. If you send a HUP signal to the process it will lookup this name again, so you don't need to restart the server if the remote node changes its IP address. *Multinet is a product, and probably a trademark, of Process Software. http://www.process.com and is available free for hobbyist use. The protocol used here was reverse engineered by Mark Berryman and Christine Caulfield. OPTIONS
-v Be verbose and dump packet contents to stderr -1 Advertise as a level 1 router -2 Advertise as a level 2 router (default) -D Make the tapX device into the default DECnet device. This will force all traffic to non-local nodes down the Multinet link. IMPOR- TANT: Due to a kernel bug you should not use this option unless you are using a Linux kernel version 2.6.17 or later. -p priority Router priority. Default is 64 -P port Port to talk to Multinet on (default is 700). Ony change this if you know the Multinet server is listening on a different port -m MTU Maximum size of packets. (default 576) -t secs Timeout for IP connections. If no traffic is seen on the IP connection after this time then the daemon will attempt to restart it. -H hello timer How often HELLO messages are sent (default 60) in seconds. EXAMPLES
