92 LHT65N-E5 is configured as LoRaWAN OTAA Class A sensor by default. Each LHT65N-E5 is shipped with a worldwide unique set of OTAA keys. To use LHT65N-E5 in a LoRaWAN network, first, we need to put the OTAA keys in LoRaWAN Network Server and then activate LHT65N-E5.

96 If LHT65N-E5 is within the coverage of this LoRaWAN network. LHT65N-E5 can join the LoRaWAN network automatically. After successfully joining, LHT65N-E5 will start to measure environment temperature, humidity & illumination, and start to transmit sensor data to the LoRaWAN server.

440 == 2.6 Datalog Feature ==
441
442
443 (((
444 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.
445 )))
446
447
448 === 2.6.1 Ways to get datalog via LoRaWAN ===
449
450
451 There are two methods:
452
453 (% style="color:blue" %)**Method 1:** (%%)IoT Server sends a downlink LoRaWAN command to [[poll the value>>||anchor="H2.6.4Pollsensorvalue"]] for specified time range.
454
455
456 (% style="color:blue" %)**Method 2: **(%%)Set PNACKMD=1, 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.
457
458
459 (% style="color:red" %)**Note for method 2:**
460
461 * a) LHT65N-E5 will do an ACK check for data records sending to make sure every data arrive server.
462 * 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.
463
464 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
465
466
467 [[image:image-20220703111700-2.png||_mstalt="426244" height="381" width="1119"]]
468
469
470 === 2.6.2 Unix TimeStamp ===
471
472
473 LHT65N-E5 uses Unix TimeStamp format based on

485
486
487 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
488
489
490 === 2.6.3 Set Device Time ===
491
492
493 (((
494 (% style="color:blue" %)**There are two ways to set device's time:**
495 )))
496
497 (((
498 **1.  Through LoRaWAN MAC Command (Default settings)**
499 )))
500
501 (((
502 User need to set SYNCMOD=1 to enable sync time via MAC command.
503 )))
504
505 (((
506 Once LHT65N-E5 Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to LHT65N-E5. If LHT65N-E5 fails to get the time from the server, LHT65N-E5 will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
507 )))
508
509 (((
510 (% 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.**

512
513
514 (((
515 **2. Manually Set Time**
516 )))
517
518 (((
519 User needs to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.
520 )))
521
522
523 === 2.6.4 Poll sensor value ===
524
525
526 User can poll sensor value based on timestamps from the server. Below is the downlink command.
527
528 (% border="1" cellspacing="3" style="background-color:#f2f2f2; width:428px" %)
529 |(% style="background-color:#4f81bd; color:white; width:59px" %)**1byte**|(% style="background-color:#4f81bd; color:white; width:128px" %)**4bytes**|(% style="background-color:#4f81bd; color:white; width:124px" %)**4bytes**|(% style="background-color:#4f81bd; color:white; width:117px" %)**1byte**
530 |(% style="width:58px" %)31|(% style="width:128px" %)Timestamp start|(% style="width:123px" %)Timestamp end|(% style="width:116px" %)Uplink Interval
531
532 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.
533
534 For example, downlink command (% _mstmutation="1" %)**31 5FC5F350 5FC6 0160 05**(%%)
535
536 Is to check 2020/12/1 07:40:00 to 2020/12/1 08:40:00’s data
537
538 Uplink Internal =5s, means LHT65N-E5 will send one packet every 5s. range 5~~255s.
