404 -Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, LHT65N will store the reading for future retrieving purposes. There are two ways for IoT servers to get datalog from LHT65N.
402 +This feature is always enabled. When user wants to retrieve the sensor value, he can send a poll command from the IoT platform to ask LHT65N to send the value in the required time slot.
