24 == 1.1 What is D2x-LB/LS LoRaWAN Temperature Sensor ==
25
26
27 The Dragino D2x-LB/LS is a (% style="color:blue" %)**LoRaWAN Temperature Sensor**(%%) for Internet of Things solution. D2x-LB/LS has 1 ~~ 3 temperature probes. D2x-LB/LS will convert the Temperature reading to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.
28
29 The LoRa wireless technology used in D2x-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.
30
31 The temperature sensor used in D2x-LB/LS can (% style="color:blue" %)**measure -55°C ~~ 125°C with accuracy ±0.5°C (max ±2.0 °C)**(%%).
32
33 D2x-LB/LS supports (% style="color:blue" %)**temperature alarm feature**(%%), user can set temperature alarm for instant notice. D2x-LB/LS supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.
34
35 D2x-LB/LS has max 3 probes which measure maximum 3 temperature points.
36
37 D2x-LB/LS (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
38
39 D2x-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.
40
41 Each D2x-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.

215 = 2. Configure D2x-LB/LS to connect to LoRaWAN network =
216
217 == 2.1 How it works ==
218
219
220 The D2x-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 D2x-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
221
222
223 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
224
225
226 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.
227
228 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.
229
230
231 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from D2x-LB/LS.
232
233 Each D2x-LB/LS is shipped with a sticker with the default device EUI as below:
234
235 [[image:image-20230426084024-1.png||alt="图片-20230426084024-1.png" height="236" width="508"]]
236
237
238 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

262
263 Press the button for 5 seconds to activate the D2x-LB/LS.
264
265 (% 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.
266
267 After join success, it will start to upload messages to TTN and you can see the messages in the panel.

482 == 2.5 Datalog Feature ==
483
484
485 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/LS will store the reading for future retrieving purposes.
486
487
488 === 2.5.1 Ways to get datalog via LoRaWAN ===
489
490
491 Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], D2x-LB/LS will wait for ACK for every uplink, when there is no LoRaWAN network,D2x-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.
492
493 * a) D2x-LB/LS will do an ACK check for data records sending to make sure every data arrive server.
494 * b) D2x-LB/LS will send data in **CONFIRMED Mode** when PNACKMD=1, but D2x-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 D2x-LB/LS gets a ACK, D2x-LB/LS will consider there is a network connection and resend all NONE-ACK Message.
495
496
497 === 2.5.2 Unix TimeStamp ===
498
499
500 D2x-LB/LS uses Unix TimeStamp format based on

510 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
511
512
513 === 2.5.3 Set Device Time ===
514
515
516 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
517
518 Once D2x-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 D2x-LB/LS. If D2x-LB/LS fails to get the time from the server, D2x-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).
519
520 (% 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.**

547
548 * Poll Message Flag is set to 1.
549
550 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
551
552 For example, in US915 band, the max payload for different DR is:
553
554 (% style="color:blue" %)**a) DR0:**(%%) max is 11 bytes so one entry of data
555
556 (% style="color:blue" %)**b) DR1:**(%%) max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
557

559
560 (% style="color:blue" %)**d) DR3: **(%%)total payload includes 22 entries of data.
