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.

gnunet-nat-server
GNUNET-NAT-SERVER(1) General Commands Manual GNUNET-NAT-SERVER(1) NAME
gnunet-nat-server - help GNUnet setup test network setup with NAT SYNOPSIS
gnunet-nat-server [options] PORT DESCRIPTION
Normal GNUnet end-users should not concern themselves with gnunet-nat-server. In fact, distributions are encouraged to consider not ship- ping it at all. Running gnunet-nat-server's is similar to running hostlist servers: it is a special service to the community with special requirements and no benefit to those running the service. This program will listen on the specified PORT for incoming requests to test a peer's network connectivity. Incoming requests can ask it to connect to a given IPv4 address (and port) using TCP or UDP and to send a 2-byte test message using the specified address. The program can also be asked to send a "fake" ICMP response message to a given IPv4 address (for autonomous NAT traversal --- see the description in the respective research paper). The idea is that gnunet-nat-server will be run on some trusted hosts with unrestricted connectivity to allow GNUnet users to test their network configuration. As written, the code allows any user on the Internet to cause the gnunet-nat-server to send 2-bytes of arbitrary data to any TCP or UDP port at any address. We believe that this is generally harmless. When running gnunet-nat-server, make sure to use a configuration that disables most NAT options but enables 'enable_nat_client' and sets 'internal_address' to the global IP address of your local host. Also, the gnunet-helper-nat-client should be installed locally and run with root privileges (SUID), otherwise the gnunet-nat-server will not work properly. Note that gnunet-nat-server could be run via gnunet-arm but typically is not. Also, the name of the host and port that gnunet-nat-server is run on should be specified in the NATSERVER option in the [setup] section of the configuration file of hosts that are supposed to auto- configure with this server. OPTIONS
-c FILENAME, --config=FILENAME Use the configuration file FILENAME. BUGS
