/* This is an example program which reads in the 3-axis acceleration, pressure, and temperature data from
 * a FRDM-FXS-MULTI sensor board. It then uses an MTSAS SocketModem Shield board to send the read data over
 * a cellular connection to Aeris AerCloud using an MQTT client protocol.

// PLEASE READ THIS!
//
// Example was created for the following hardware:
//   ST Nucleo F401RE   http://developer.mbed.org/platforms/ST-Nucleo-F401RE/
//   Freescale Multi-Sensor Shield https://developer.mbed.org/components/Freescale-Multi-Sensor-Shield/

//   MultiTech MTSMC-H5 GSM Socket Modem http://www.multitech.com/models/92503252LF#gsc.tab=0
//
// To get the sample running, you'll need to fill in the following parameters below
//   Your cellular provider's APN: _APN
//   AerCloud API Key: _AERCLOUD_API_APIKEY
//   AerCloud Account ID: _AERCLOUD_ACCOUNT_ID
//   AerCloud Container: _ACERCLOUD_CONTAINER
//
// The AerCloud container needa a Data Model with the following schema:
//    accel_x  FLOAT
//    accel_y  FLOAT 
//    accel-Z  FLOAT
//    pressure FLOAT
//    temperature FLOAT
//
// To check if data has made it in the container, create a long polling subscription in AerPort and they use the following url in your browswer
//
// http://longpoll.aercloud.aeris.com/v1/1/containers/subscriptions/<subscrption_name>/notificationChannels/longPoll?apiKey=<api_key>
//
// You should see the something that looks like this in the browser:
// {"sclContentInstances":[{"sclId":"nucleo-0001","containerId":"Nucleo_Test","contentInstance":{"id":"a40c8e60-8248-11e4-8b38-0677f0dfdf5e","contentSize":90,"creationTime":1418420922950,"content":{"contentType":"application/json","contentTypeBinary":"{\"x\":0.005615,\"y\":-0.041260,\"z\":1.015137,\"pressure\":101098.500000,\"temperature\":25.125000}"}}},
