Example of Kaltiot Push Notification for Embedded devicesHEADmaster

This example demonstrates receiving push notifications from the Kaltiot
IoT Cloud, and then displays the content on the screen. The Kaltiot
gateway daemon will notify the registered application that the new
message is available to sync. You can send push notifications to the
devices running this example by using the IoT-Devices service in the
Kaltiot Console or Kaltiot HTTP Rest API with curl command. This example
works on both Linux64 and Raspberry Pi devices.
