	96	1. Configure LSE01 to connect to LoRaWAN network
	97	11. How it works
	98
	99	The LSE01 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 power on the LSE0150. It will automatically join the network via OTAA and start to send the sensor value
	100
	101
	102	In case you can’t set the OTAA keys in the LoRaWAN OTAA server, and you have to use the keys from the server, you can [[use AT Commands >>path:#_Using_the_AT]]to set the keys in the LSE01.

4.2	108	11. Quick guide to connect to LoRaWAN server (OTAA)
	109
	110	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 [[LG308>>url:http://www.dragino.com/products/lora/item/140-lg308.html]] as a LoRaWAN gateway in this example.
	111

	113	[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image003.png]]
	114
	115
	116	The LG308 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.
	117
	118
	119	Step 1: Create a device in TTN with the OTAA keys from LSE01.
	120
	121	Each LSE01 is shipped with a sticker with the default device EUI as below:
	122
	123
	124
	125
	126	You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:
	127
	128
	129	Add APP EUI in the application

	144
	145	Step 2: Power on LSE01
	146
	147
	148	Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).

	157
	158
	159
	160
	161
	162	Step 3: The LSE01 will auto join to the TTN network. After join success, it will start to upload messages to TTN and you can see the messages in the panel.

12.2	221	11.
4.2	222	111. Battery Info
	223
	224	Check the battery voltage for LSE01.
	225
	226	Ex1: 0x0B45 = 2885mV
	227
	228	Ex2: 0x0B49 = 2889mV

	231
12.2	232	1.
	233	11.
4.2	234	111. Soil Moisture
	235
	236	Get the moisture content of the soil. The value range of the register is 0-10000(Decimal), divide this value by 100 to get the percentage of moisture in the soil.
	237
	238	For example, if the data you get from the register is 0x05 0xDC, the moisture content in the soil is
	239
	240	05DC(H) = 1500(D) /100 = 15%.
	241
	242
12.2	243	1.
	244	11.
4.2	245	111. Soil Temperature
	246
	247	Get the temperature in the soil. The value range of the register is -4000 - +800(Decimal), divide this value by 100 to get the temperature in the soil. For example, if the data you get from the register is 0x09 0xEC, the temperature content in the soil is
	248
	249	Example:
	250
	251	If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
	252
	253	If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C
	254
	255
12.2	256	1.
	257	11.
4.2	258	111. Soil Conductivity (EC)
	259
	260	Obtain soluble salt concentration in soil or soluble ion concentration in liquid fertilizer or planting medium,. The value range of the register is 0 - 20000(Decimal)( Can be greater than 20000).
	261
	262	For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
	263
	264
	265	Generally, the EC value of irrigation water is less than 800uS / cm.
	266
12.2	267	1.
	268	11.
4.2	269	111. MOD
	270
	271	Firmware version at least v2.1 supports changing mode.
	272
	273	For example, bytes[10]=90
	274
	275	mod=(bytes[10]>>7)&0x01=1.
	276
	277
	278	Downlink Command:
	279
	280	If payload = 0x0A00, workmode=0
	281
	282	If payload = 0x0A01, workmode=1
	283

	286	11.
4.2	287	111. Decode payload in The Things Network
	288
	289	While using TTN network, you can add the payload format to decode the payload.

	291
	292	[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image009.png]]
	293
	294	The payload decoder function for TTN is here:

	298
12.2	299	1.
4.2	300	11. Uplink Interval
	301
	302	The LSE01 by default uplink the sensor data every 20 minutes. User can change this interval by AT Command or LoRaWAN Downlink Command. See this link:
	303
	304	[[http:~~/~~/wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Commands#Change_Uplink_Interval>>url:http://wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Commands#Change_Uplink_Interval]]
	305
12.2	306	1.
4.2	307	11. Downlink Payload
	308
	309	By default, LSE50 prints the downlink payload to console port.

	321	Set TDC
	322
	323	If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
	324
	325	Payload: 01 00 00 1E TDC=30S

4.2	340	11. Show Data in DataCake IoT Server
	341
	342	[[DATACAKE>>url:https://datacake.co/]] provides a human friendly interface to show the sensor data, once we have data in TTN, we can use [[DATACAKE>>url:https://datacake.co/]] to connect to TTN and see the data in DATACAKE. Below are the steps:
	343
	344
	345	Step 1: Be sure that your device is programmed and properly connected to the network at this time.
	346
	347	Step 2: To configure the Application to forward data to DATACAKE you will need to add integration. To add the DATACAKE integration, perform the following steps:
	348

	355
	356
	357
	358
	359	Step 3: Create an account or log in Datacake.
	360
	361	Step 4: Search the LSE01 and add DevEUI.

	718
	719	The LSE01 battery is a combination of a 4000mAh Li/SOCI2 Battery and a Super Capacitor. The battery is non-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.
	720
	721
	722	The battery is designed to last for more than 5 years for the LSN50.
	723
	724
	725	The battery related documents as below:

4.2	741	111. Battery Note
	742
	743	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.

4.2	748	111. Replace the battery
	749
	750	If Battery is lower than 2.7v, user should replace the battery of LSE01.
	751
	752
	753	You can change the battery in the LSE01.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.
	754
	755
	756	The default battery pack of LSE01 includes a ER18505 plus super capacitor. If user can’t find this pack locally, they can find ER18505 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)

	901
8.3	902	How to set up LSE01 to work in 8 channel mode By default, the frequency bands US915, AU915, CN470 work in 72 frequencies. Many gateways are 8 channel gateways, and in this case, the OTAA join time and uplink schedule is long and unpredictable while the end node is hopping in 72 frequencies.
4.2	903
	904
	905	You can configure the end node to work in 8 channel mode by using the AT+CHE command. The 500kHz channels are always included for OTAA.
	906
	907
	908	For example, in US915 band, the frequency table is as below. By default, the end node will use all channels (0~~71) for OTAA Join process. After the OTAA Join, the end node will use these all channels (0~~71) to send uplink packets.
	909
8.2	910	[[image:image-20220606154726-3.png]]
4.2	911
	912	When you use the TTN network, the US915 frequency bands use are:
	913
	914	* 903.9 - SF7BW125 to SF10BW125
	915	* 904.1 - SF7BW125 to SF10BW125
	916	* 904.3 - SF7BW125 to SF10BW125
	917	* 904.5 - SF7BW125 to SF10BW125
	918	* 904.7 - SF7BW125 to SF10BW125
	919	* 904.9 - SF7BW125 to SF10BW125
	920	* 905.1 - SF7BW125 to SF10BW125
	921	* 905.3 - SF7BW125 to SF10BW125
	922	* 904.6 - SF8BW500
	923
	924	Because the end node is now hopping in 72 frequency, it makes it difficult for the devices to Join the TTN network and uplink data. To solve this issue, you can access the device via the AT commands and run:
