32 (((
33 The Dragino (% style="color:blue" %)**SDI-12-LB/LS**(%%) is a (% style="color:blue" %)**SDI-12 to LoRaWAN Converter **(%%)designed for Smart Agriculture solution.
34 )))
35
36 (((
37 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.
38 )))
39
40 (((
41 SDI-12-LB/LS 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.
42 )))
43
44 (((
45 The LoRa wireless technology used in SDI-12-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.
46 )))
47
48 (((
49 SDI-12-LB/LS is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%) or (% style="color:blue" %)**solar powered + Li-ion battery,**(%%) it is designed for long term use up to 5 years.
50 )))
51
52 (((
53 Each SDI-12-LB/LS 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.

187
188 == 2.1 How it works ==
189
190
191 The SDI-12-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 activate the SDI-12-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
192
193
194 == 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
195
196
197 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 [[image:image-20250416151346-2.png]]
200
201
202 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.

204
205 (% style="color:blue" %)**Step 1**(%%): Create a device in TTN with the OTAA keys from SDI-12-LB/LS.

241
242 While using TTN network, you can add the payload format to decode the payload.
243
244 There is no fix payload decoder in LoRaWAN server because the SDI-12 sensors returns are different. User need to write the decoder themselves for their case.

282 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.
283
284 If SDI-12 sensor return value after get these commands, //SDI-12-LB/LS// will uplink the return on FPORT=100, otherwise, if there is no response from SDI-12 sensor. //SDI-12-LB/LS// will uplink NULL (0x 4E 55 4C 4C) to server.

1105
1106 * 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.
1107
1108 * If these SDI-12 sensors are powered by external power source. It will add 300uA in the total current in SDI-12-LB/LS.

1275
1276 SDI-12-LB will wait for ACK for every uplink, when there is no LoRaWAN network,SDI-12-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.

1294
1295
1296
1297 Once SDI-12-LB Joined LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to SDI-12-LB. If SDI-12-LB fails to get the time from the server, SDI-12-LB will use the internal time and wait for next time request (AT+SYNCTDC to set the time request period, default is 10 days).
1298
1299 (% 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.**

1322 User can poll sensor value based on timestamps from the server. Below is the downlink command.

1329
1330 Timestamp start and Timestamp end use Unix TimeStamp format as mentioned above. Devices will reply with all data log during this time period, use the uplink interval.
1331
1332 For example, downlink command (% _mstmutation="1" %)**31 68253B6E 68253E23 05**(%%)
1333
1334 Is to check 2025/05/15 00:55:10 to 2025/05/15 01:06:43's data

2040 == 7.4 Why is the data uploaded to the LoRaWAN platform node empty and fProt~=0? ==
2041
2042
2043 This is due to The length of bytes sent by the node is limited by the lorawan protocol, and the fixed DR needs to be adjusted to improve this problem.
2044
2045 Please refer to the following link for the number of bytes limited by different frequencies and different DRs in the lorawan protocol
