MQTT Library Test
-----------------

This MQTT application tests the low-level API for packet handling.
No network activity is involved in this test, so ** theoretically **
it can be run on almost any board already supported by Zephyr and
with enough RAM/ROM.

Build and Run
-------------

* QEMU x86

  Build & run:
  make run

* Arduino 101

  Build:
  make BOARD=arduino_101

  Flashing:
  sudo dfu-util -a x86_app -D outdir/arduino_101/zephyr.bin

* NXP Freedom-K64F (frdm-k64f)

  Build:
  make pristine && make BOARD=frdm_k64f

  Firmware version:
  Version: 0226
