 *   Senet is the leading IoT network services provider for low cost, long range IoT applications.             *
 *   Senet provides network services for application developers who are searching for an affordable IoT        *
 *   network to launch and scale their solutions.                                                              *

 *   This program demonstrates how to connect to Senet's public network with an mDot and sends some data       *
 *                                                                                                             *
 *   On the Senet Developer Portal website you can view device transactions and even configure forwarding      *
 *   to IoT data collection and analysis services.                                                             *
