Send temperature value to AllThingsTalk

The SODAQ SARA AFF has an temperature sensor inside the Accelerometer.

AllthingsTalk

Create or login to AllThingsTalk. Create a new device if you don't have one.
Create an asset "t" as a Number.

Under SettingsAuthentication you can find your device id and token.
Add the device id and token to the code and upload the example to your board.
Go to AllThingsTalk and see the temperature measured by the accelerometer.
