Simple Mbed Cloud client application using features of K64 & K66 including Ethernet and SD Card

Fork of mbed-cloud-example_K64_K66 by Mac Lobdell

DEPRECATED

This example application is not maintained and not recommended. It uses an old version of Mbed OS, Pelion DM, and Arm toolchain. It doesn't work with Mbed Studio.
