15 == 1.1 What is S31x-LB LoRaWAN Temperature & Humidity Sensor ==
16
17
18 The Dragino S31x-LB is a (% style="color:blue" %)**LoRaWAN Temperature and Humidity Sensor**(%%) for Internet of Things solution. It is used to measure the (% style="color:blue" %)**surrounding environment temperature and relative air humidity precisely**(%%), and then upload to IoT server via LoRaWAN wireless protocol.
19
20 The temperature & humidity sensor used in S31x-LB is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides a strong reliability and long-term stability. The SHT31 is fixed in a (% style="color:blue" %)**waterproof anti-condensation casing**(%%) for long term use.
21
22 The LoRa wireless technology used in S31x-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.
23
24 S31x-LB supports (% style="color:blue" %)**Temperature & Humdity alarm feature,**(%%) user can set temperature alarm for instant notice. S31x-LB supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.
25
26 S31x-LB has max 3 probes which measure maximum 3 temperature points.
27
28 S31x-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
29
30 S31x-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
31
32 Each S31x-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.

168
169 == 2.1 How it works ==
170
171
172 The S31x-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 S31x-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
173
174
175 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
176
177
178 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.
179
180
181 [[image:1675144005218-297.png]]
182
183
184 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.
185
186
187 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB.
188
189 Each S31x-LB is shipped with a sticker with the default device EUI as below:

222 Press the button for 5 seconds to activate the S31x-LB.
223
224 (% style="color:green" %)**Green led**(%%) will fast blink 5 times, device will enter (% style="color:blue" %)**OTA mode**(%%) for 3 seconds. And then start to JOIN LoRaWAN network. (% style="color:green" %)**Green led**(%%) will solidly turn on for 5 seconds after joined in network.
225
226 After join success, it will start to upload messages to TTN and you can see the messages in the panel.

380 == 2.5 Datalog Feature ==
381
382
383 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, D2x-LB will store the reading for future retrieving purposes.
384
385
386 === 2.5.1 Ways to get datalog via LoRaWAN ===
387
388
389 Set [[PNACKMD=1>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LHT65N%20LoRaWAN%20Temperature%20%26%20Humidity%20Sensor%20Manual/#H4.13AutoSendNone-ACKmessages]], D2x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,D2x-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.
390
391 * a) D2x-LB will do an ACK check for data records sending to make sure every data arrive server.
392 * b) D2x-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but D2x-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 D2x-LB gets a ACK, D2x-LB will consider there is a network connection and resend all NONE-ACK Message.
393
394 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
395

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

413
414 === 2.5.3 Set Device Time ===
415
416
417 User need to set SYNCMOD=1 to enable sync time via MAC command.
418
419 Once D2x-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to D2x-LB. If D2x-LB fails to get the time from the server, D2x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
420
421 **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.**

452
453 **a) DR0:** max is 11 bytes so one entry of data
454
455 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
