	21	+== 1.1 ​What is SDI-12 to LoRaWAN Converter ==
	22	+
	23	+
	24	+The Dragino **SDI-12-LB** is a **SDI-12 to LoRaWAN Converter **designed for Smart Agriculture solution.
	25	+
	26	+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.
	27	+
	28	+**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.
	29	+
	30	+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.
	31	+
	32	+**SDI-12-LB** is powered by **8500mAh Li-SOCI2 battery**, it is designed for long term use up to 5 years.
	33	+
	34	+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.

	177	+1. Configure SDI-12 to connect to LoRaWAN network
	178	+11. How it works
	179	+
	180	+The SDI-12-LB is configured as **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.
	181	+
	182	+
	183	+1.
	184	+11. ​Quick guide to connect to LoRaWAN server (OTAA)
	185	+
	186	+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.
	187	+
	188	+
	189	+[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image008.png]]
	190	+
	191	+
	192	+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.
	193	+
	194	+
	195	+**Step 1**: Create a device in TTN with the OTAA keys from SDI-12-LB.
	196	+
	197	+Each SDI-12-LB is shipped with a sticker with the default device EUI as below:

	201	+
	202	+
	203	+
	204	+
	205	+
	206	+You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

	230	+
	231	+**Step 2**: Activate on SDI-12-LB
	232	+
	233	+
	234	+Press the button for 5 seconds to activate the SDI-12-LB.
	235	+
	236	+
	237	+**Green led** will fast blink 5 times, device will enter **OTA mode** for 3 seconds. And then start to JOIN LoRaWAN network. **Green led** will solidly turn on for 5 seconds after joined in network.

	253	+11.
	254	+111. Basic SDI-12 debug command
	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	+
	259	+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.

	443	+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.
	444	+
	445	+
	446	+* ** AT Command:**
	447	+
	448	+**AT+COMMANDx=var1,var2,var3,var4.**
	449	+
	450	+var1: SDI-12 command , for example: 0RC0!
	451	+
	452	+var2: Wait timeout for return. (unit: second)
	453	+
	454	+var3: Whether to send //addrD0!// to get return after var2 timeout. 0: Don’t Send //addrD0!//; 1: Send //addrD0!//.
	455	+
	456	+var4: validation check for return. If return invalid, SDI-12-LB will resend this command. Max 2 retries.
	457	+
	458	+0  No validation check;
	459	+
	460	+1  Check if return chars are printable char(0x20 ~~ 0x7E);
	461	+
	462	+2  Check if there is return from SDI-12 sensor
	463	+
	464	+3  Check if return pass CRC check ( SDI-12 command var1 must include CRC request);
	465	+
	466	+
	467	+Each AT+COMMANDx is followed by a **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.
	468	+
	469	+
	470	+**AT+DATACUTx** : This command defines how to handle the return from AT+COMMANDx, max return length is 100 bytes.
	471	+
	472	+|(((
	473	+AT+DATACUTx=a,b,c
	474	+
	475	+a: length for the return of AT+COMMAND
	476	+
	477	+b:1: grab valid value by byte, max 6 bytes. 2: grab valid value by bytes section, max 3 sections.
	478	+
	479	+c: define the position for valid value.
	480	+)))
	481	+
	482	+For example, if return from AT+COMMAND1 is “013METER   TER12 112T12-00024895” ,. Below AT+DATACUT1 will get different result to combine payload:
	483	+
	484	+

	489	+
	490	+* ** Downlink Payload:**
	491	+
	492	+**0xAF**  downlink command can be used to set AT+COMMANDx or AT+DATACUTx.
	493	+
	494	+
	495	+**Note : if user use AT+COMMANDx to add a new command, he also need to send AT+DATACUTx downlink.**
	496	+
	497	+
	498	+Format: ** AF MM NN LL XX XX XX XX YY**
	499	+
	500	+Where:
	501	+
	502	+* MM: the AT+COMMAND or AT+DATACUT to be set. Value from 01 ~~ 0F,
	503	+* NN:  1: set the AT+DATACUT value ; 2: set the AT+DATACUT value.
	504	+* LL:  The length of AT+COMMAND or AT+DATACUT command
	505	+* XX XX XX XX: AT+COMMAND or AT+DATACUT command
	506	+* YY:  If YY=0, RS485-LN will execute the downlink command without uplink; if YY=1, RS485-LN will execute an uplink after got this command.
	507	+
	508	+Example:
	509	+
	510	+**AF 03 01 07 30 4D 43 21 01 01 01 00**: Same as AT+COMMAND3=**0MC!**,** 1**,** 1**,** 1**
	511	+
	512	+**AF 03 02 06 10 01 05 06 09 0A 00**: Same as AT+DATACUT3=**16**,**1**,**5+6+9+10**

	515	+
	516	+
	517	+**Clear SDI12 Command**
	518	+
	519	+The AT+COMMANDx and AT+DATACUTx settings are stored in special location, user can use below command to clear them.
	520	+
	521	+
	522	+* ** AT Command:**
	523	+
	524	+**~ AT+CMDEAR=mm,nn**   mm: start position of erase ,nn: stop position of erase
	525	+
	526	+
	527	+Etc. AT+CMDEAR=1,10 means erase AT+COMMAND1/AT+DATACUT1 to AT+COMMAND10/AT+DATACUT10
	528	+
	529	+
	530	+* ** Downlink Payload:**
	531	+
	532	+**~ 0x09 aa bb**  same as AT+CMDEAR=aa,bb
	533	+
	534	+
	535	+
	536	+
	537	+**command combination**
	538	+
	539	+Below shows a screen shot how the results combines together to a uplink payload.
	540	+
	541	+[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image029.png]]
	542	+
	543	+
	544	+If user don’t want to use DATACUT for some command, he simply want to uplink all returns. AT+ALLDATAMOD can be set to 1.
	545	+
	546	+**AT+ALLDATAMOD** will simply get all return and don’t do CRC check as result for SDI-12 command. AT+DATACUTx command has higher priority, if AT+DATACUTx has been set, AT+ALLDATAMOD will be ignore for this SDI-12 command.
	547	+
	548	+
	549	+For example: as below photo, AT+ALLDATAMOD=1, but AT+DATACUT1 has been set, AT+DATACUT1 will be still effect the result.
	550	+
	551	+
	552	+[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image030.png]]
	553	+
	554	+
	555	+If AT+ALLDATAMOD=1, **FX,X** will be added in the payload, FX specify which command is used and X specify the length of return. for example in above screen, F1 05 means the return is from AT+COMMAND1 and the return is 5 bytes.
	556	+
	557	+
	558	+
	559	+**Compose Uplink**
	560	+
	561	+**AT+DATAUP=0**
	562	+
	563	+Compose the uplink payload with value returns in sequence and send with A SIGNLE UPLINK.
	564	+
	565	+Final Payload is Battery Info+PAYVER + VALID Value from RETURN1 + Valid Value from RETURN2 + … + RETURNx
	566	+
	567	+Where PAYVER is defined by AT+PAYVER, below is an example screen shot.

	606	+
	607	+Uplink payloads have two types:
	608	+
	609	+* Distance Value: Use FPORT=2
	610	+* Other control commands: Use other FPORT fields.
	611	+

	1226	+1. Battery & how to replace
	1227	+11. Battery Type
	1228	+
	1229	+SDI-12-LB is equipped with a [[8500mAH ER26500 Li-SOCI2 battery>>url:https://www.dragino.com/downloads/index.php?dir=datasheet/Battery/ER26500/]]. The battery is un-rechargeable battery with low discharge rate targeting for 8~~10 years use. This type of battery is commonly used in IoT target for long-term running, such as water meter.
	1230	+
	1231	+
	1232	+The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

	1255	+
	1256	+
	1257	+Instruction to use as below:
	1258	+
	1259	+
	1260	+Step 1: Downlink the up-to-date DRAGINO_Battery_Life_Prediction_Table.xlsx from:

	1292	+111. ​Battery Note
	1293	+
	1294	+The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.
	1295	+
	1296	+
	1297	+1.
	1298	+11.
	1299	+111. ​Replace the battery
	1300	+
	1301	+You can change the battery in the SDI-12-LB.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
	1302	+
	1303	+
	1304	+The default battery pack of SDI-12-LB includes a ER26500 plus super capacitor. If user can’t find this pack locally, they can find ER26500 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)
