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.

211
212 The DDS75-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 DDS75-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

423 == 2.6 Datalog Feature ==
424
425
426 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, DDS75-LB will store the reading for future retrieving purposes.
427
428
429 === 2.6.1 Ways to get datalog via LoRaWAN ===
430
431
432 Set PNACKMD=1, DDS75-LB will wait for ACK for every uplink, when there is no LoRaWAN network,DDS75-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.
433
434 * (((
435 a) DDS75-LB will do an ACK check for data records sending to make sure every data arrive server.
436 )))
437 * (((
438 b) DDS75-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but DDS75-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 DDS75-LB gets a ACK, DDS75-LB will consider there is a network connection and resend all NONE-ACK messages.
439 )))
440
441 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

460 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
461
462
463 === 2.6.3 Set Device Time ===
464
465
466 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
467
468 Once DDS75-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 DDS75-LB fails to get the time from the server, DDS75-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
469
470 (% 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.**

473 === 2.6.4 Poll sensor value ===
