2.2	24
	25
37.7	26	The Dragino (% style="color:blue" %)SDI-12-LB(%%) is a (% style="color:blue" %)SDI-12 to LoRaWAN Converter (%%)designed for Smart Agriculture solution.
9.2	27
2.2	28	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.
	29
37.8	30	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.
2.2	31
37.8	32	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.
2.2	33
37.8	34	SDI-12-LB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
2.2	35
37.8	36	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.

9.2	178
	179
19.2	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.

2.2	182
19.2	183	== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
2.2	184
	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.

2.2	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:

	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.

2.2	548

35.2	550	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.
2.2	551
37.2	552	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.
2.2	553
	554
35.2	555	For example: as below photo, AT+ALLDATAMOD=1, but AT+DATACUT1 has been set, AT+DATACUT1 will be still effect the result.

2.2	559
	560
	561	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.

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.
37.3	1020
	1021
2.2	1022	The discharge curve is not linear so can’t simply use percentage to show the battery level. Below is the battery performance.

37.3	1069	=== 4.3.1 Battery Note ===
2.2	1070
	1071
	1072	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.
	1073
	1074
37.3	1075	=== 4.3.2 Replace the battery ===
2.2	1076
	1077
37.5	1078	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.
2.2	1079
37.5	1080	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)
