436 == 2.6 Datalog Feature ==
437
438
439 (((
440 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, LHT65S-E5 will store the reading for future retrieving purposes. There are two ways for IoT servers to get datalog from LHT65S-E5.
441 )))
442
443
444 === 2.6.1 Ways to get datalog via LoRaWAN ===
445
446
447 There are two methods:
448
449 (% style="color:blue" %)**Method 1:** (%%)IoT Server sends a downlink LoRaWAN command to [[poll the value>>||anchor="H2.6.4Pollsensorvalue"]] for specified time range.
450
451
452 (% style="color:blue" %)**Method 2: **(%%)Set PNACKMD=1, LHT65S-E5 will wait for ACK for every uplink, when there is no LoRaWAN network, LHT65S-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.
453
454
455 (% style="color:red" %)**Note for method 2:**
456
457 * a) LHT65S-E5 will do an ACK check for data records sending to make sure every data arrive server.
458 * b) LHT65S-E5 will send data in **CONFIRMED Mode** when PNACKMD=1, but LHT65S-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 LHT65S-E5 gets a ACK, LHT65S-E5 will consider there is a network connection and resend all NONE-ACK Message.
459
460 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
461

464
465
466 === 2.6.2 Unix TimeStamp ===
467
468
469 LHT65S-E5 uses Unix TimeStamp format based on
470
471
472 [[image:image-20220523001219-11.png||_mstalt="450450" height="97" width="627"]]

476 User can get this time from link:  [[https:~~/~~/www.epochconverter.com/>>url:https://www.epochconverter.com/]] :

481
482
483 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
484
485
486 === 2.6.3 Set Device Time ===
487
488
489 (((
490 (% style="color:blue" %)**There are two ways to set device's time:**
491 )))
492
493 (((
494 **1.  Through LoRaWAN MAC Command (Default settings)**
495 )))
496
497 (((
498 User need to set SYNCMOD=1 to enable sync time via MAC command.
499 )))
500
501 (((
502 Once LHT65S-E5 Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to LHT65S-E5. If LHT65S-E5 fails to get the time from the server, LHT65S-E5 will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
503 )))
504
505 (((
506 (% style="color:red" %)**Note: LoRaWAN Server need to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature, Chirpstack,TTN V3 v3 and loriot support but TTN V3 v2 doesn't support. If server doesn't support this command, it will through away uplink packet with this command, so user will lose the packet with time request for TTN V3 v2 if SYNCMOD=1.**
507 )))
508
509
510 (((
511 **2. Manually Set Time**
512 )))
513
514 (((
515 User needs to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
516 )))
517
518
519 === 2.6.4 Poll sensor value ===
520
521
522 User can poll sensor value based on timestamps from the server. Below is the downlink command.
523
524 (% border="1" cellspacing="5" style="background-color:#f2f2f2; width:428px" %)
525 |(% style="width:58px" %)1byte|(% style="width:128px" %)4bytes|(% style="width:123px" %)4bytes|(% style="width:116px" %)1byte
526 |(% style="width:58px" %)31|(% style="width:128px" %)Timestamp start|(% style="width:123px" %)Timestamp end|(% style="width:116px" %)Uplink Interval
527
528 Timestamp start and Timestamp end use Unix TimeStamp format as mentioned above. Devices will reply with all data log during this time period, use the uplink interval.
529
530 For example, downlink command (% _mstmutation="1" %)**31 5FC5F350 5FC6 0160 05**(%%)
531
532 Is to check 2020/12/1 07:40:00 to 2020/12/1 08:40:00’s data
533
534 Uplink Internal =5s，means LHT65S-E5 will send one packet every 5s. range 5~~255s.
535
536
537 === 2.6.5 Datalog Uplink payload ===
