 Our aim here is to use Octave to configure the mangOH board so that it uploads its light sensor value to the cloud every two minutes.

-In Octave, display **Resources** page:
+Ensure that [mangOH welcome application is disabled](settingup/Disable welcome application) and that heartbeat and developer mode are configured as described in [this page](settingup/Heartbeat and developer mode).

-Set following resources:
-* **cloudInterface/store_forward/heartbeat_on_empty**: **true**
-* **cloudInterface/store_forward/period**: **60**
-
-This guarantees that the board contacts the cloud every 60 s at least. Thus, we are sure to be able to download a new configuration to the mangOH board, even if we disable all data uploads and developer mode (see below).
