  = 2. Use S31-NB to communicate with IoT Server =
  == 2.1 Send data to IoT server via NB-IoT network ==
--The S31-NB is equipped with a NB-IoT module, the pre-loaded firmware in S31-NB will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by S31-NB.
++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.
--Below shows the network structure:
++== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
--[[image:1692415924540-357.png]]
++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.
--There are two version: (% style="color:blue" %)**-GE**(%%) and (% style="color:blue" %)**-1D**(%%) version of S31-NB.
++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.
--(% style="color:blue" %)**GE Version**(%%): This version doesn’t include SIM card or point to any IoT server. User needs to use AT Commands to configure below two steps to set S31-NB send data to IoT server.
++(% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from S31x-LB.

++== 2.5 Datalog Feature ==
--== 2.3 Test Uplink and Change Update Interval ==
++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.
--By default, Sensor will send uplinks (% style="color:blue" %)**every 2 hours**(%%) & AT+NOUD=8
--User can use below commands to change the (% style="color:blue" %)**uplink interval**.
++=== 2.5.1 Ways to get datalog via LoRaWAN ===
--(% style="color:#037691" %)**AT+TDC=600 ** (%%)      ~/~/ Set Update Interval to 600s
--User can also push the button for more than 1 seconds to activate an uplink.
++Set [[PNACKMD=1>>||anchor="H2.5.4DatalogUplinkpayload28FPORT3D329"]], 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.
++* (((
++a) S31x-LB will do an ACK check for data records sending to make sure every data arrive server.
++)))
++* (((
++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.
++)))
--== 2.4 Multi-Samplings and One uplink ==
++Below is the typical case for the auto-update datalog feature (Set PNACKMD=1)

--To save battery life, S31-NB will sample temperature & humidity data every 15 minutes and send one uplink every 2 hours. So each uplink it will include 8 stored data + 1 real-time data. They are defined by:
--* (% style="color:#037691" %)**AT+TR=900**   (%%)  ~/~/  The unit is seconds, and the default is to record data once every 900 seconds (15 minutes, the minimum can be set to 180 seconds)
++=== 2.5.2 Unix TimeStamp ===
--* (% style="color:#037691" %)**AT+NOUD=8**  (%%)~/~/   The device uploads 8 sets of recorded data by default. Up to 32 sets of record data can be uploaded.

--On each sampling define by AT+TR ( default 900s or 15 minutes), when the value exceed the range, it will trigger an Alarm and immediately sends a uplink.
++So, we can use AT+TIMESTAMP=1611889405 or downlink 3060137afd00 to set the current time 2021 – Jan ~-~- 29 Friday 03:03:25
--(% style="color:blue" %)**AT Commands:**
--(% style="color:#037691" %)**AT+ SHHUM=min,max**
++=== 2.5.3 Set Device Time ===
--Example: AT+ SHHUM=50,80 ~/~/ Alarm when humidity lower than 50 or higher than 80.
++User need to set (% style="color:blue" %)**SYNCMOD=1**(%%) to enable sync time via MAC command.
--(% style="color:#037691" %)**AT+ SHTEMP=min,max**
++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).
--Example: AT+ SHTEMP=20,30 ~/~/ Alarm when temperature lower than 20 or higher than 30
++(% 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.**
--(% style="color:red" %)**Notice:**
++=== 2.5.4 Datalog Uplink payload (FPORT~=3) ===
--* To disable Alarm, user can set min and max to same value , such as (% style="color:#037691" %)**AT+SHTEMP=0,0.**
--* If user only want to send only min or max, user can set the alarm to a value that device won’t reach. For example: (% style="color:#037691" %)**AT+SHTEMP=-80,0.**
++The Datalog uplinks will use below payload format.
