33 (((
34 The Dragino (% style="color:blue" %)**SDI-12-LB/LS**(%%) is a (% style="color:blue" %)**SDI-12 to LoRaWAN Converter **(%%)designed for Smart Agriculture solution.
35 )))
36
37 (((
38 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.
39 )))
40
41 (((
42 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.
43 )))
44
45 (((
46 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.
47 )))
48
49 (((
50 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.
51 )))
52
53 (((
54 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.

188
189 == 2.1 How it works ==
190
191
192 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.
193
194
195 == 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
196
197
198 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.
199
200 [[image:image-20250416151346-2.png]]
201
202
203 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.

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

242
243 While using TTN network, you can add the payload format to decode the payload.
244
245 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
283 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.
284
285 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.

1098
1099 * 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.
1100
1101 * If these SDI-12 sensors are powered by external power source. It will add 300uA in the total current in SDI-12-LB/LS.

1276 (% style="color:blue" %)**Method 2: **(%%)Set PNACKMD=1, 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.
1277
1278

1281 * a) SDI-12-LB will do an ACK check for data records sending to make sure every data arrive server.
1282 * b) SDI-12-LB will send data in **CONFIRMED Mode** when PNACKMD=1, but SDI-12-LB won't re-transmit the packet if it doesn't get ACK, it will just mark it as a NONE-ACK message. In a future uplink if SDI-12-LB gets a ACK, SDI-12-LB will consider there is a network connection and resend all NONE-ACK Message.

1344
1345 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.
1346
1347 For example, downlink command (% _mstmutation="1" %)**31 68253B6E 68253E23 05**(%%)
1348

2003 == 7.4 Why is the data uploaded to the LoRaWAN platform node empty and fProt~=0? ==
2004
2005
2006 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.

2008 Please refer to the following link for the number of bytes limited by different frequencies and different DRs in the lorawan protocol
