17 == 1.1 What is S31x-NB NB-IoT Temperature & Humidity Sensor ==
18
19
20 The Dragino S31-NB and S31B-NB are **NB-IoT Temperature and Humidity Sensor** for Internet of Things solution. It is used to measure the surrounding **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 **waterproof anti-condensation casing** for long term use.
23
24 S31-NB supports different uplink methods include **TCP, MQTT, UDP** for different application requirement. and Support Uplinks to various IoT Servers.
25
26 S31-NB is powered by **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).

207
208 == 2.1 How it works ==
209
210
211 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.
212
213
214 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
215
216
217 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.
218
219 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.
220
221
222 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB.
223
224 Each S31x-LB is shipped with a sticker with the default device EUI as below:

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.

451 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
452
453
454 === 2.5.3 Set Device Time ===
455
456
457 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
458
459 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).
460
461 (% 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.**

494
495
496 **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)
497
498 **Poll Message Flag**: 1: This message is a poll message reply.
499
500 * Poll Message Flag is set to 1.
501
502 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
503
504 For example, in US915 band, the max payload for different DR is:
505
506 **a) DR0:** max is 11 bytes so one entry of data
507
508 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
509
510 **c) DR2:** total payload includes 11 entries of data
511
512 **d) DR3: **total payload includes 22 entries of data.
513
514 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0
