18
19
20 The Dragino S31-NB and S31B-NB are (% style="color:blue" %)**NB-IoT Temperature and Humidity Sensor**(%%) for Internet of Things solution. It is used to measure the surrounding (% style="color:blue" %)**environment temperature and relative air humidity precisely**(%%), and then upload to IoT server via NB-IoT network*.
21
22 The temperature & humidity sensor used in S31-NB 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.
23
24 S31-NB supports different uplink methods include (% style="color:blue" %)**TCP, MQTT, UDP** for different application requirement. and Support Uplinks to various IoT Servers.
25
26 S31-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to several years. (Real-world battery life depends on the use environment, update period and uplink method. Please check related Power Analyze report).

239
240
241 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.
242
243
244 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
245
246
247 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.
248
249 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.
250
251
252 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB.
253
254 Each S31x-LB is shipped with a sticker with the default device EUI as below:

443
444 == 2.5 Datalog Feature ==
445
446
447 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.
448
449
450 === 2.5.1 Ways to get datalog via LoRaWAN ===
451
452
453 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.
454
455 * (((
456 a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
457 )))
458 * (((
459 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.
460 )))
461
462 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

480
481 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
482
483
484 === 2.5.3 Set Device Time ===
485
486
487 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
488
489 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).
490
491 (% 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.**

524
525
526 **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)
527
528 **Poll Message Flag**: 1: This message is a poll message reply.
529
530 * Poll Message Flag is set to 1.
531
532 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
533
534 For example, in US915 band, the max payload for different DR is:
535
536 **a) DR0:** max is 11 bytes so one entry of data
537
538 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
539
540 **c) DR2:** total payload includes 11 entries of data
541
542 **d) DR3: **total payload includes 22 entries of data.
