378 +(((
379 +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-E5 will store the reading for future retrieving purposes. There are two ways for IoT servers to get datalog from LHT65N-E5.
380 +)))
381 +
382 +
383 +=== 2.6.1 Ways to get datalog via LoRaWAN ===
384 +
385 +
386 +There are two methods:
387 +
388 +(% style="color:blue" %)**Method 1:** (%%)IoT Server sends a downlink LoRaWAN command to [[poll the value>>||anchor="H2.6.4Pollsensorvalue"]] for specified time range.

390 +
391 +(% style="color:blue" %)**Method 2: **(%%)Set [[PNACKMD=1>>||anchor="H4.13AutoSendNone-ACKmessages"]], LHT65N-E5 will wait for ACK for every uplink, when there is no LoRaWAN network, LHT65N-E5 will mark these records with non-ack messages and store the sensor data, and it will send all messages (10s interval) after the network recovery.
392 +
393 +
394 +(% style="color:red" %)**Note for method 2:**
395 +
396 +* a) LHT65N-E5 will do an ACK check for data records sending to make sure every data arrive server.
397 +* b) LHT65N-E5 will send data in **CONFIRMED Mode** when PNACKMD=1, but LHT65N-E5 won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if LHT65N-E5 gets a ACK, LHT65N-E5 will consider there is a network connection and resend all NONE-ACK Message.
398 +
399 +Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
