Richard Kuo / Mbed OS NTOUEE-mbed-Client

This is a simple mbed client example demonstrating, registration of a device with mbed Device Connector and reading and writing values as well as deregistering on different Network Interfaces including Ethernet, WiFi, 6LoWPAN ND and Thread respectively.

Simplify UPD and IPv4/IPv6 selections



Idea is that MESH has to have hard-coded IPv6 server address, because

it does not have DNS capability. Other networks should have.



Also, UDP must be used with MESH - other networks we want to default to

TCP because it is typically more reliable (UDP gets closed due to firewalls).



Thirdly, IPv4/IPv6 selection should now happen automatically through

the mbed_app.json selections with no need to modify the .h-file anymore

by modifying the

            "lwip.ipv4-enabled": false,

            "lwip.ipv6-enabled": true

selections accordingly.
