BlueShadow 7:3d2a3fd4a523 1 /** Combination of MultiTech HTTPS Example using json with NXP Freescale sensor board and IBM Bluemix
BlueShadow 2:1df4b48824b1 2 *
BlueShadow 7:3d2a3fd4a523 3 * Configures the Sensor board for Accelerometer, cellular radio, brings up the cellular link,
BlueShadow 2:1df4b48824b1 4 * and does HTTPS POST requests.
mfiore 0:6ce1803b7a03 5 * 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.
mfiore 0:6ce1803b7a03 6 *
BlueShadow 2:1df4b48824b1 7 *
BlueShadow 2:1df4b48824b1 8 *
BlueShadow 2:1df4b48824b1 9 * The following hardware is required to successfully run this program:
BlueShadow 2:1df4b48824b1 10 * - MultiTech UDK2 (4" square white PCB with Arduino headers, antenna
BlueShadow 2:1df4b48824b1 11 * connector, micro USB ports, and 40-pin connector for Dragonfly)
BlueShadow 2:1df4b48824b1 12 * - MultiTech Dragonfly (1"x2" green PCB with Telit radio)
BlueShadow 7:3d2a3fd4a523 13 * - Freescale (NXP) Sensor Board
BlueShadow 2:1df4b48824b1 14 *
BlueShadow 2:1df4b48824b1 15 * What this program does:
BlueShadow 7:3d2a3fd4a523 16 * - reads data from sensor
BlueShadow 2:1df4b48824b1 17 * - prints all sensor data to debug port on a periodic basis
BlueShadow 7:3d2a3fd4a523 18 * - sends data to BlueMix
BlueShadow 2:1df4b48824b1 19 * - All data is sent to a specific location determined by the student login.
BlueShadow 2:1df4b48824b1 20 * - BlueMix cloud platform (user must create own account and configure a device
BlueShadow 2:1df4b48824b1 21 *
BlueShadow 2:1df4b48824b1 22 * Setup:
BlueShadow 2:1df4b48824b1 23 * - Correctly insert SIM card into Dragonfly
BlueShadow 2:1df4b48824b1 24 * - Seat the Dragonfly on the UDK2 board
BlueShadow 2:1df4b48824b1 25 * - Connect an antenna to the connector on the Dragonfly labled "M"
BlueShadow 2:1df4b48824b1 26 * - Stack the Base Shield on the UDK2 Arduino headers
BlueShadow 2:1df4b48824b1 27 * - Stack the MEMs board on top of the Base Shield
BlueShadow 2:1df4b48824b1 28 * - Plug in the power cable
BlueShadow 2:1df4b48824b1 29 * - Plug a micro USB cable into the port below and slightly to the
BlueShadow 7:3d2a3fd4a523 30 * left of the Dragonfly near the RF Connector (NOT the port on the Dragonfly)
BlueShadow 2:1df4b48824b1 31 *
BlueShadow 2:1df4b48824b1 32 * Go have fun and make something cool!
