17 == 1.1 What is LoRaWAN Distance Detection Sensor ==
18
19
20 The Dragino DDS45-LB is a (% style="color:blue" %)** LoRaWAN Distance Detection Sensor**(%%) for Internet of Things solution. It is used to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses (% style="color:blue" %)** ultrasonic sensing technology**(%%) for (% style="color:blue" %)**distance measurement**(%%), and (% style="color:blue" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The DDS45-LB can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, bottom water level monitoring, etc.
21
22 It detects the distance(% style="color:blue" %)**  between the measured object and the sensor**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
23
24 The LoRa wireless technology used in DDS45-LB allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
25
26 DDS45-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
27
28 DDS45-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
29
30 Each DDS45-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

204
205
206 The DDS45-LB is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the DDS45-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

213 Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.

405 == 2.6 Datalog Feature ==
406
407
408 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, DDS45-LB will store the reading for future retrieving purposes.
409
410
411 === 2.6.1 Ways to get datalog via LoRaWAN ===
412
413
414 Set PNACKMD=1, DDS45-LB will wait for ACK for every uplink, when there is no LoRaWAN network,DDS45-LB 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.
415
416 * (((
417 a) DDS45-LB will do an ACK check for data records sending to make sure every data arrive server.
418 )))
419 * (((
420 b) DDS45-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but DDS45-LB 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 DDS45-LB gets a ACK, DDS45-LB will consider there is a network connection and resend all NONE-ACK messages.
421 )))
422
423 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

442 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
443
444
445 === 2.6.3 Set Device Time ===
446
447
448 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
449
450 Once DDS45-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to DDS45-LB. If DDS45-LB fails to get the time from the server, DDS45-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
451
452 (% 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.**

631
632 == 6.1  What is the frequency plan for DDS45-LB? ==
633
634
635 DDS45-LB use the same frequency as other Dragino products. User can see the detail from this link:  [[Introduction>>doc:Main.End Device Frequency Band.WebHome||anchor="H1.Introduction"]]
636
637
638 == 6.2  Can I use DDS45-LB in condensation environment? ==
639
640
641 DDS45-LB is not suitable to be used in condensation environment. Condensation on the DDS45-LB probe will affect the reading and always got 0.

645
646 == 7.1  Why I can't join TTN V3 in US915 / AU915 bands? ==

650
651
652 == 7.2  AT Command input doesn't work ==
653
654
655 In the case if user can see the console output but can't type input to the device. Please check if you already include the (% style="color:blue" %)**ENTER**(%%) while sending out the command. Some serial tool doesn't send (% style="color:blue" %)**ENTER**(%%) while press the send key, user need to add ENTER in their string.
656
657
658 == 7.3  Why does the sensor reading show 0 or "No sensor" ==
659
660
661 ~1. The measurement object is very close to the sensor, but in the blind spot of the sensor.
662
663 2. Sensor wiring is disconnected
664
665 3. Not using the correct decoder
666
667
668 == 7.4  Abnormal readings The gap between multiple readings is too large or the gap between the readings and the actual value is too large ==
669
670
671 1) Please check if there is something on the probe affecting its measurement (condensed water, volatile oil, etc.)
672
673 2) Does it change with temperature, temperature will affect its measurement
674
675 3) If abnormal data occurs, you can turn on DEBUG mode, Please use downlink or AT COMMAN to enter DEBUG mode.
