18 == 1.1 What is S31x-LB LoRaWAN Temperature & Humidity Sensor ==
19
20
21 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.
22
23 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.
24
25 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.
26
27 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.
28
29 S31x-LB has max 3 probes which measure maximum 3 temperature points.
30
31 S31x-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
32
33 S31x-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
34
35 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.

178
179 == 2.1 How it works ==
180
181
182 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.
183
184
185 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
186
187
188 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.
189
190 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.
191
192
193 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB.
194

378
379 == 2.5 Datalog Feature ==
380
381
382 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 will store the reading for future retrieving purposes.
383
384
385 === 2.5.1 Ways to get datalog via LoRaWAN ===
386
387
388 Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayload28FPORT3D329"]], S31x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,S31x-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.
389
390 * a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
391 * b) S31x-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but S31x-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 S31x-LB gets a ACK, S31x-LB will consider there is a network connection and resend all NONE-ACK messages.
392
393 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

412 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
413
414
415 === 2.5.3 Set Device Time ===
416
417
418 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
419
420 Once S31x-LB 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. If S31x-LB fails to get the time from the server, S31x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
421
422 (% 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.**
423

443
444 **No ACK Message**:  1: This message means this payload is fromn Uplink Message which doesn't get ACK from the server before ( for **PNACKMD=1** feature)
445
446 **Poll Message Flag**: 1: This message is a poll message reply.
447
448 * Poll Message Flag is set to 1.
449
450 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
451
452 For example, in US915 band, the max payload for different DR is:
453
454 **a) DR0:** max is 11 bytes so one entry of data
455
456 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
457
458 **c) DR2:** total payload includes 11 entries of data
459
460 **d) DR3: **total payload includes 22 entries of data.
461
462 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
463
464
465 **Example:**
466
467 If S31x-LB has below data inside Flash:
468
469 [[image:1682646494051-944.png]]

475 Stop time: 60066DA7= time 21/1/19 05:27:03
