+# Heartbeat
+
+In Octave, display **Resources** page:
+
+![light1-resources](uploads/9422750ba71f2b4c7c4e4e8a95c75eae/light1-resources.png)
+
+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).

+
+# Developer mode
+
+To check system behaviour in real conditions, we disable developer mode:
+* **cloudInterface/developer_mode/enable**: **false**
