23 == 1.1 What is S31x-LB/LS LoRaWAN Temperature & Humidity Sensor ==
24
25
26 The Dragino S31x-LB/LS 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.
27
28 The temperature & humidity sensor used in S31x-LB/LS 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.
29
30 The LoRa wireless technology used in S31x-LB/LS 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.
31
32 S31x-LB/LS supports (% style="color:blue" %)**Temperature & Humdity alarm feature**(%%), user can set temperature alarm for instant notice. S31x-LB/LS supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.
33
34 S31x-LB/LS (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
35
36 S31x-LB/LS is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%) or (% style="color:blue" %)**solar powered + li-on battery**(%%) it is designed for long term use up to 5 years.
37
38 Each S31x-LB/LS 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.

198 == 2.1 How it works ==
199
200
201 The S31x-LB/LS 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/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
202
203
204 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
205
206
207 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.
208
209 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.
210
211
212 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB/LS.
213
214 Each S31x-LB/LS is shipped with a sticker with the default device EUI as below:

407 Datalog Feature is to ensure IoT Server can get all sampling data from Sensor even if the LoRaWAN network is down. For each sampling, S31x-LB/LS will store the reading for future retrieving purposes.

410 === 2.5.1 Ways to get datalog via LoRaWAN ===
411
412
413 Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayload28FPORT3D329"]], S31x-LB/LS will wait for ACK for every uplink, when there is no LoRaWAN network,S31x-LB/LS 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.
414
415 * (((
416 a) S31x-LB/LS will do an ACK check for data records sending to make sure every data arrive server.
417 )))
418 * (((
419 b) S31x-LB/LS will send data in **CONFIRMED Mode** when PNACKMD=1, but S31x-LB/LS 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 S31x-LB/LS gets a ACK, S31x-LB/LS will consider there is a network connection and resend all NONE-ACK messages.
420 )))
421
422 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

441 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
442

445
446
447 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
448
449 Once S31x-LB/LS Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to S31x-LB/LS. If S31x-LB/LS fails to get the time from the server, S31x-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
450
451 (% 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.**

488 **Poll Message Flag**: 1: This message is a poll message reply.
489
490 * Poll Message Flag is set to 1.
491
492 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
493
494 For example, in US915 band, the max payload for different DR is:
495
496 **a) DR0:** max is 11 bytes so one entry of data
497
498 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
