15 == 1.1 What is D2x-LB LoRaWAN Temperature Sensor ==
16
17
18 The Dragino D2x-LB is a (% style="color:blue" %)**LoRaWAN Temperature Sensor**(%%) for Internet of Things solution. D2x-LB has 5v and 12v output , 4~~20mA, 0~~30v input interface to power and get value from Analog Sensor. D2x-LB will convert the Analog Value to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.
19
20 The LoRa wireless technology used in D2x-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.
21
22 The temperature sensor used in D2x-LB can (% style="color:blue" %)**measure -55°C ~~ 125°C with accuracy ±0.5°C (max ±2.0 °C)**(%%).
23
24 D2x-LB supports (% style="color:blue" %)**temperature alarm feature,**(%%) user can set temperature alarm for instant notice. D2x-LB supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.
25
26 D2x-LB has max 3 probes which measure maximum 3 temperature points.
27
28 D2x-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
29
30 D2x-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
31
32 Each D2x-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.

174
175 == 2.1 How it works ==
176
177
178 The D2x-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 D2x-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
179
180
181 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
182
183
184 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.
185
186
187 [[image:1675144005218-297.png]]
188
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 D2x-LB.
194
195 Each D2x-LB is shipped with a sticker with the default device EUI as below:
196

227 Press the button for 5 seconds to activate the D2x-LB.
228
229 (% 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.
230
231 After join success, it will start to upload messages to TTN and you can see the messages in the panel.

435 == 2.5 Datalog Feature ==
436
437
438 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 will store the reading for future retrieving purposes.
439
440
441 === 2.5.1 Ways to get datalog via LoRaWAN ===
442
443
444 Set [[PNACKMD=1>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LHT65N%20LoRaWAN%20Temperature%20%26%20Humidity%20Sensor%20Manual/#H4.13AutoSendNone-ACKmessages]], D2x-LB will wait for ACK for every uplink, when there is no LoRaWAN network,D2x-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.
445
446 * a) D2x-LB will do an ACK check for data records sending to make sure every data arrive server.
447 * b) D2x-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but D2x-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 D2x-LB gets a ACK, D2x-LB will consider there is a network connection and resend all NONE-ACK Message.
448
449 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

466 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
467
468
469 === 2.5.3 Set Device Time ===
470
471
472 User need to set SYNCMOD=1 to enable sync time via MAC command.
473
474 Once D2x-LB 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. If D2x-LB fails to get the time from the server, D2x-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
475
476 **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.**

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)
