438 == 2.6 Datalog Feature ==
439
440
441 (((
442 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.
443 )))
444
445
446 === 2.6.1 Ways to get datalog via LoRaWAN ===
447
448
449 There are two methods:
450
451 (% style="color:blue" %)**Method 1:** (%%)IoT Server sends a downlink LoRaWAN command to [[poll the value>>||anchor="H2.6.4Pollsensorvalue"]] for specified time range.
452
453
454 (% 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.
455
456
457 (% style="color:red" %)**Note for method 2:**
458
459 * a) LHT65S-E5 will do an ACK check for data records sending to make sure every data arrive server.
460 * 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.
461
462 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

466
467
468 === 2.6.2 Unix TimeStamp ===
469
470
471 LHT65S-E5 uses Unix TimeStamp format based on

483
484
485 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
486
487
488 === 2.6.3 Set Device Time ===
489
490
491 (((
492 (% style="color:blue" %)**There are two ways to set device's time:**

495 (((
496 **1.  Through LoRaWAN MAC Command (Default settings)**
497 )))
498
499 (((
500 User need to set SYNCMOD=1 to enable sync time via MAC command.
501 )))
502
503 (((
504 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).
505 )))
506
507 (((
508 (% 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.**
509 )))
510
511
512 (((
513 **2. Manually Set Time**
514 )))
515
516 (((
517 User needs to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
518 )))
519
520
521 === 2.6.4 Poll sensor value ===
522
523
524 User can poll sensor value based on timestamps from the server. Below is the downlink command.
525
526 (% border="1" cellspacing="5" style="background-color:#f2f2f2; width:428px" %)
527 |(% style="width:58px" %)1byte|(% style="width:128px" %)4bytes|(% style="width:123px" %)4bytes|(% style="width:116px" %)1byte
528 |(% style="width:58px" %)31|(% style="width:128px" %)Timestamp start|(% style="width:123px" %)Timestamp end|(% style="width:116px" %)Uplink Interval
529
530 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.
531
532 For example, downlink command (% _mstmutation="1" %)**31 5FC5F350 5FC6 0160 05**(%%)
533
534 Is to check 2020/12/1 07:40:00 to 2020/12/1 08:40:00’s data
535
536 Uplink Internal =5s，means LHT65S-E5 will send one packet every 5s. range 5~~255s.
537
538
539 === 2.6.5 Datalog Uplink payload ===
