199
200 == 2.1 How it works ==
201
202
203 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.
204
205
206 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
207
208
209 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.
210
211
212 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.
213
214
215 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from D2x-LB.
216
217 Each D2x-LB is shipped with a sticker with the default device EUI as below:
218
219 [[image:image-20230131134744-2.jpeg]]

247
248
249 Press the button for 5 seconds to activate the D2x-LB.
250
251 (% 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.
252
253 After join success, it will start to upload messages to TTN and you can see the messages in the panel.

456 == 2.5 Datalog Feature ==
457
458
459 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.
460
461
462 === 2.5.1 Ways to get datalog via LoRaWAN ===
463
464
465 Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], 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.
466
467 * a) D2x-LB will do an ACK check for data records sending to make sure every data arrive server.
468 * 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.
469
470 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

486
487 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
488
489
490 === 2.5.3 Set Device Time ===
491
492
493 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
494
495 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).
496
497 (% 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.**

518
519 **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)
520
521 **Poll Message Flag**: 1: This message is a poll message reply.
522
523 * Poll Message Flag is set to 1.
524
525 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
526
527 For example, in US915 band, the max payload for different DR is:
528
529 **a) DR0:** max is 11 bytes so one entry of data
530
531 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
532
533 **c) DR2:** total payload includes 11 entries of data
534
535 **d) DR3: **total payload includes 22 entries of data.
536
537 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
538

540 **Example:**
541
542 If D2x-LB has below data inside Flash:
