73.3	23	== 1.1 What is S31x-LB/LS LoRaWAN Temperature & Humidity Sensor ==
1.1	24
39.6	25
73.3	26	The Dragino S31x-LB/LS is a (% style="color:blue" %)LoRaWAN Temperature and Humidity Sensor(%%) for Internet of Things solution. It is used to measure the (% style="color:blue" %)surrounding environment temperature and relative air humidity precisely(%%), and then upload to IoT server via LoRaWAN wireless protocol.
1.1	27
73.3	28	The temperature & humidity sensor used in S31x-LB/LS is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides a strong reliability and long-term stability. The SHT31 is fixed in a (% style="color:blue" %)waterproof anti-condensation casing(%%) for long term use.
1.1	29
73.3	30	The LoRa wireless technology used in S31x-LB/LS allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
1.1	31
73.3	32	S31x-LB/LS supports (% style="color:blue" %)Temperature & Humdity alarm feature(%%), user can set temperature alarm for instant notice. S31x-LB/LS supports Datalog feature, it can save the data when there is no LoRaWAN network and uplink when network recover.

73.4	195	The S31x-LB/LS 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/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

In a future uplink if S31x-LB/LS gets a ACK, S31x-LB/LS will consider there is a network connection and resend all NONE-ACK messages.

1.1	442
73.4	443	Once S31x-LB/LS 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/LS. If S31x-LB/LS fails to get the time from the server, S31x-LB/LS will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
1.1	444
14.24	445	(% 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.
