18 == 1.1 What is LoRaWAN Distance Detection Sensor ==
19
20
21 The Dragino DDS75-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 DDS75-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.
22
23 It detects the distance(% style="color:blue" %)**  between the measured object and the sensor**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
24
25 The LoRa wireless technology used in SW3L-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.
26
27 SW3L-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
28
29 SW3L-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
30
31 Each SW3L-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.

182
183
184 The SW3L-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 SW3L-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

190
191 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.
192
193 The LPS8v2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

571
572 == 2.5 Datalog Feature ==
573
574
575 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, SW3L-LB will store the reading for future retrieving purposes.
576
577
578 === 2.5.1 Ways to get datalog via LoRaWAN ===
579
580
581 Set PNACKMD=1, SW3L-LB will wait for ACK for every uplink, when there is no LoRaWAN network,SW3L-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.
582
583 * (((
584 a) SW3L-LB will do an ACK check for data records sending to make sure every data arrive server.
585 )))
586 * (((
587 b) SW3L-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but SW3L-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 SW3L-LB gets a ACK, SW3L-LB will consider there is a network connection and resend all NONE-ACK messages.
588 )))
589
590 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
591
592 [[image:http://wiki.dragino.com/xwiki/bin/download/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LHT65N%20LoRaWAN%20Temperature%20%26%20Humidity%20Sensor%20Manual/WebHome/image-20220703111700-2.png?width=1119&height=381&rev=1.1||alt="图片-20220703111700-2.png" height="381" width="1119"]]

609 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
610

612 === 2.5.3 Set Device Time ===
613
614
615 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
616
617 Once SW3L-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to SW3L-LB. If SW3L-LB fails to get the time from the server, SW3L-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
618
619 (% 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.**

764 This feature is to monitor and send Alarm for continuously water flow.

766
767 (((
768 Example case is for Toilet water monitoring, if some one push toilet button, the toilet will have water flow. If the toilet button has broken and can't returned to original state, the water flow will keep for hours or days which cause huge waste for water.
