28 +The NDS03A will send periodically data (% style="color:blue" %)**every 4 hours** (%%)as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/close event, instead, NDS03A can count each open event and uplink periodically.
