184
185 == 2.1 How it works ==
186
187
188 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.
189
190
191 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
192
193
194 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.
195
196
197
198
199 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.
200
201
202 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB.
203
204 Each S31x-LB is shipped with a sticker with the default device EUI as below:

389 == 2.5 Datalog Feature ==
390
391
392 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.
393
394
395 === 2.5.1 Ways to get datalog via LoRaWAN ===
396
397
398 Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayloadA028FPORT3D329"]], 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.
399
400 * a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
401 * 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.
402
403 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

419
420 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
421
422
423 === 2.5.3 Set Device Time ===
424
425
426 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
427
428 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).
429
430 (% 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.**
431
432
433 === 2.5.4 Datalog Uplink payload (FPORT~=3) ===

451
452 **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)
453
454 **Poll Message Flag**: 1: This message is a poll message reply.
455
456 * Poll Message Flag is set to 1.
457
458 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
459
460 For example, in US915 band, the max payload for different DR is:
461
462 **a) DR0:** max is 11 bytes so one entry of data
463
464 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
465
466 **c) DR2:** total payload includes 11 entries of data
467
468 **d) DR3: **total payload includes 22 entries of data.
469
470 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
471

473 **Example:**
474
475 If D2x-LB has below data inside Flash:
