32 +
33 +(((
34 +SDI-12-LB has SDI-12 interface and support 12v output to power external SDI-12 sensor. It can get the environment data from SDI-12 sensor and sends out the data via LoRaWAN wireless protocol.

36 +
37 +(((
38 +The LoRa wireless technology used in SDI-12-LB 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.

181 +
182 +== 2.1 How it works ==
183 +
184 +
185 +The SDI-12-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 activate the SDI-12-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
186 +
187 +
188 +== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
189 +
190 +
191 +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 +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.

451 +AT+COMMANDx & AT+DATACUTx
452 +
453 +User can define max 15 SDI-12 Commands (AT+COMMAND1 ~~ AT+COMMANDF). On each uplink period (TDC time, default 20 minutes), SDI-12-LB will send these SDI-12 commands and wait for return from SDI-12 sensors. SDI-12-LB will then combine these returns and uplink via LoRaWAN.

467 +

475 +
476 +
477 +Each AT+COMMANDx is followed by a (% style="color:blue" %)**AT+DATACUT**(%%) command. AT+DATACUT command is used to take the useful string from the SDI-12 sensor so the final payload will have the minimum length to uplink.
478 +

842 +* AT Command Connection: See [[FAQ>>||anchor="H7.FAQ"]].
843 +* LoRaWAN Downlink instruction for different platforms: See [[IoT LoRaWAN Server>>http://wiki.dragino.com/xwiki/bin/view/Main/]] section.

845 +There are two kinds of commands to configure SDI-12-LB, they are:
846 +
847 +* (% style="color:blue" %)**General Commands**.
848 +
849 +These commands are to configure:
850 +
851 +* General system settings like: uplink interval.
852 +* LoRaWAN protocol & radio related command.
853 +
854 +They are same for all Dragino Device which support DLWS-005 LoRaWAN Stack. These commands can be found on the wiki:
