19 == 1.1 What is SW3L-LB LoRaWAN Flow Sensor ==
20
21
22 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.**
23
24 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.
25
26 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.
27
28 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.
29
30 SW3L-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
31
32 SW3L-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
33
34 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.

190
191
192 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.

197
198
199 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.
200
201 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.

580 == 2.5 Datalog Feature ==
581
582
583 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.
584
585
586 === 2.5.1 Ways to get datalog via LoRaWAN ===
587
588
589 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.
590
591 * (((
592 a) SW3L-LB will do an ACK check for data records sending to make sure every data arrive server.
593 )))
594 * (((
595 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.
596 )))
597
598 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
599

603 === 2.5.2 Unix TimeStamp ===

606 SW3L-LB uses Unix TimeStamp format based on

617 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
618

620 === 2.5.3 Set Device Time ===
621
622
623 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
624
625 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).
626
627 (% 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.**

778 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.
