/** Combination of MultiTech HTTPS Example using json with NXP Freescale sensor board and IBM Bluemix
 *
 * Configures the Sensor board for Accelerometer, cellular radio, brings up the cellular link,
 * and does HTTPS POST requests.
 * To do HTTPS requests with a certain server, the root certificate used to validate that server's certificate must be installed. See ssl_certificates.h for information on how to get the proper root certificate.
 *
 *
  *
 * The following hardware is required to successfully run this program:
 *   - MultiTech UDK2 (4" square white PCB with Arduino headers, antenna
 *     connector, micro USB ports, and 40-pin connector for Dragonfly)
 *   - MultiTech Dragonfly (1"x2" green PCB with Telit radio)
 *   - Freescale (NXP) Sensor Board
 *
 * What this program does:
 *   - reads data from sensor
 *   - prints all sensor data to debug port on a periodic basis
 *   - sends data to BlueMix
 *   - All data is sent to a specific location determined by the student login.
 *   - BlueMix cloud platform (user must create own account and configure a device
 *
 * Setup:
 *   - Correctly insert SIM card into Dragonfly
 *   - Seat the Dragonfly on the UDK2 board
 *   - Connect an antenna to the connector on the Dragonfly labled "M"
 *   - Stack the Base Shield on the UDK2 Arduino headers
 *   - Stack the MEMs board on top of the Base Shield
 *   - Plug in the power cable
 *   - Plug a micro USB cable into the port below and slightly to the
 *     left of the Dragonfly near the RF Connector (NOT the port on the Dragonfly)
 *
 * Go have fun and make something cool!
