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.

180 == 2.1 How it works ==
181
182
183 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.

187
188
189 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.

193
194
195 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.
196
197
198 (% style="color:blue" %)**Step 1**(%%): Create a device in TTN with the OTAA keys from SDI-12-LB.
199

247 === 2.3.1 Basic SDI-12 debug command ===
248
249
250 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.
251
252 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.

470 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.

967 * The product page and reference command see above example 2,3,4
968
969 * 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.
970
971 * 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.
972
973 * If these SDI-12 sensors are powered by external power source. It will add 300uA in the total current in SDI-12-LB.
