187
188 == 2.1 How it works ==
189
190
191 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.
192
193
194 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
195
196
197 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.
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

387
388 == 2.5 Datalog Feature ==
389
390
391 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.
392
393
394 === 2.5.1 Ways to get datalog via LoRaWAN ===
395
396
397 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.
398
399 * a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
400 * 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.
401
402 Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

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

451 **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)
452
453 **Poll Message Flag**: 1: This message is a poll message reply.
454
455 * Poll Message Flag is set to 1.
456
457 * Each data entry is 11 bytes, to save airtime and battery, devices will send max bytes according to the current DR and Frequency bands.
458
459 For example, in US915 band, the max payload for different DR is:
460
461 **a) DR0:** max is 11 bytes so one entry of data
462
463 **b) DR1:** max is 53 bytes so devices will upload 4 entries of data (total 44 bytes)
464
465 **c) DR2:** total payload includes 11 entries of data
466
467 **d) DR3: **total payload includes 22 entries of data.
468
469 If devise doesn't have any data in the polling time. Device will uplink 11 bytes of 0   
470
471
472 **Example:**
473
474 If S31x-LB has below data inside Flash:
