168 = 2. Configure S31x-LB to connect to LoRaWAN network =
169
170 == 2.1 How it works ==
171
172
173 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.
174
175
176 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
177
178
179 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.
180
181 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.
182
183
184 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB.
185

368
369
370 == 2.5 Datalog Feature ==
371
372
373 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.
374
375
376 === 2.5.1 Ways to get datalog via LoRaWAN ===
377
378
379 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.
380
381 * a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
382 * 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.
383
384 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)
385

400
401 So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
402
403
404 === 2.5.3 Set Device Time ===
405
406
407 User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
408
409 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).
410
411 (% 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.**

432
433 **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)
434
435 **Poll Message Flag**: 1: This message is a poll message reply.
436
437 * Poll Message Flag is set to 1.
438
439 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
440
441 For example, in US915 band, the max payload for different DR is:
442
443 **a) DR0:** max is 11 bytes so one entry of data
444
445 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
446
447 **c) DR2:** total payload includes 11 entries of data
448
449 **d) DR3: **total payload includes 22 entries of data.
450
451 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
452
453
454 **Example:**
455
456 If S31x-LB has below data inside Flash:
457
458 [[image:1682646494051-944.png]]
