By default, the Spark Core connects to the Cloud and processes messages automatically. However there are many cases where a user will want to take control over that connection. The following methods are available to control the connectivity of the Spark Core.

System modes

There are three available system modes: AUTOMATIC, MANUAL_CONNECT, and MANUAL. These modes describe how connectivity is handled.

System modes must be called before the setup() function.

System.mode(AUTOMATIC)

// The most basic event, without data.
Spark.publish("motion-detected");

// Some events require additional data.
Spark.publish("temperature", "19 F");  

// You can set a TTL to persist data in the cloud...
Spark.publish("lake-depth/1", "28", 21600);

// ...and make events private for secure applications.
