18 == 1.1 What is LoRaWAN Distance Detection Sensor ==
19
20
21 The Dragino SW3L-LB is a (% style="color:blue" %)**LoRaWAN Flow Sensor**(%%). It detects water flow volume and uplink to IoT server via LoRaWAN network. User can use this to(% style="color:blue" %)** monitor the water usage for buildings.**
22
23 The SW3L-LB will send water flow volume every 20 minutes. It can also (% style="color:blue" %)**detect the water flow status**(%%) and (% style="color:blue" %)**send Alarm**(%%), to avoid the waste for water usage such as broken toilet case.
24
25 SW3L-LB is designed for both indoor and outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.
26
27 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.
28
29 SW3L-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
30
31 SW3L-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
32
33 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.

183 == 2.1 How it works ==
184
185
186 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.

191
192
193 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.
194
195 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.

573
574 == 2.5 Datalog Feature ==
575
576
577 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.
578
579
580 === 2.5.1 Ways to get datalog via LoRaWAN ===
581
582
583 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.
584
585 * (((
586 a) SW3L-LB will do an ACK check for data records sending to make sure every data arrive server.
587 )))
588 * (((
589 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.
590 )))
591
592 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
593

600 SW3L-LB uses Unix TimeStamp format based on

611 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
612
613
614 === 2.5.3 Set Device Time ===
615
616
617 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
618
619 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).
620
621 (% 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.**
