642 642  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.

653 653  1. Set [[PNACKMD=1>>||anchor="H4.13AutoSendNone-ACKmessages"]], LHT65N will wait for ACK for every uplink, when there is no LoRaWAN network, LHT65N will store the sensor data, and it will send all messages after network recover.
