+//   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
