23
24
25 (((
26 The Dragino (% style="color:blue" %)**SDI-12-LB**(%%) is a (% style="color:blue" %)**SDI-12 to LoRaWAN Converter **(%%)designed for Smart Agriculture solution.
27 )))
28
29 (((
30 SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous [[serial communications>>url:https://en.wikipedia.org/wiki/Serial_communication]] protocol for intelligent sensors that monitor environment data. SDI-12 protocol is widely used in Agriculture sensor and Weather Station sensors.
31 )))
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.
35 )))
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.
39 )))
40
41 (((
42 SDI-12-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
43 )))
44
45 (((
46 Each SDI-12-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

184
185 == 2.1 How it works ==
186
187
188 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.
189
190
191 == 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
192
193
194 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
200 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.
201
202
203 (% style="color:blue" %)**Step 1**(%%): Create a device in TTN with the OTAA keys from SDI-12-LB.
204
205 Each SDI-12-LB is shipped with a sticker with the default device EUI as below:

253 === 2.3.1 Basic SDI-12 debug command ===
254
255
256 User can run some basic SDI-12 command to debug the connection to the SDI-12 sensor. These commands can be sent via AT Command or LoRaWAN downlink command.
257
258 If SDI-12 sensor return value after get these commands, //SDI-12-LB// will uplink the return on FPORT=100, otherwise, if there is no response from SDI-12 sensor. //SDI-12-LB// will uplink NULL (0x 4E 55 4C 4C) to server.

469 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.

964
965 * The product page and reference command see above example 2,3,4
966
967 * All of these SDI-12 sensors use the same address (address 0) by default. So we need to change their address to different address, by using **aAb!** command. See above example.
968
969 * The sensor needs to be powered to a steady statue. So the 12VT time need to be set to the maximum stable time for the sensors. in this example, it is 13 seconds.
970
971 * If these SDI-12 sensors are powered by external power source. It will add 300uA in the total current in SDI-12-LB.
