* 8/12/2016  I will be making mistakes in this code.
* 8/15/2016  I2C bus in the code is on D14/D15 Arduino Pinout.  FRDM-STBD-AGM01 board is jumpered
*   to use the wrong pins vs the code.  Move the Jumpers from I2C-SCL1 to 0 and I2C-SDA1 to 0

/** Combination of MultiTech HTTPS Example
 *
 * Configures the Sensor board for Ambient Light, 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)
 *   - NXP Freesclae FRDM-STBC-AGM01
 *     3-axis accelerometer + 3-axis magnetometer, 3-axis gyroscope,
 *
 * What this program does:
 *   - reads data from all sensors
 *   - prints all sensor data to debug port on a periodic basis
 *   - optionally send 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 (NOT the port on the Dragonfly)
 *
 * Go have fun and make something cool!

/*
 * Sample Program Description:
 *   This Program will enable to Multi-Tech Dragonfly platform to utilize NXP Freescale FRDM-STBC-AGM01 Shield Board.
 *   This program will initialize sensors on the shield and then read back the sensor data.
 *   Data will then be output to the UART Debug Terminal.
