4.2	96
	97	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.

15.2	100	[[image:1654503992078-669.png]]
4.2	101
	102
	103	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.
	104
	105
	106	Step 1: Create a device in TTN with the OTAA keys from LSE01.
	107
	108	Each LSE01 is shipped with a sticker with the default device EUI as below:
	109
17.2	110	[[image:image-20220606163732-6.jpeg]]

4.2	207	111. Battery Info
	208
	209	Check the battery voltage for LSE01.
	210
	211	Ex1: 0x0B45 = 2885mV
	212
	213	Ex2: 0x0B49 = 2889mV

	216
15.5	217	1.
	218	11.
4.2	219	111. Soil Moisture
	220
	221	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.
	222
	223	For example, if the data you get from the register is 0x05 0xDC, the moisture content in the soil is
	224
	225	05DC(H) = 1500(D) /100 = 15%.
	226
	227
15.5	228	1.
	229	11.
4.2	230	111. Soil Temperature
	231
	232	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
	233
	234	Example:
	235
	236	If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
	237
	238	If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C

15.5	241	1.
	242	11.
4.2	243	111. Soil Conductivity (EC)
	244
	245	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).
	246
	247	For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
	248
	249
	250	Generally, the EC value of irrigation water is less than 800uS / cm.
	251
15.5	252	1.
	253	11.
4.2	254	111. MOD
	255
	256	Firmware version at least v2.1 supports changing mode.
	257
	258	For example, bytes[10]=90
	259
	260	mod=(bytes[10]>>7)&0x01=1.
	261
	262
	263	Downlink Command:
	264
	265	If payload = 0x0A00, workmode=0
	266
	267	If payload = 0x0A01, workmode=1

4.2	272	111. Decode payload in The Things Network
	273
	274	While using TTN network, you can add the payload format to decode the payload.

	283
15.5	284	1.
4.2	285	11. Uplink Interval
	286
	287	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:
	288
	289	[[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]]
	290
15.5	291	1.
4.2	292	11. Downlink Payload
	293
	294	By default, LSE50 prints the downlink payload to console port.

	306	Set TDC
	307
	308	If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
	309
	310	Payload: 01 00 00 1E TDC=30S

4.2	325	11. Show Data in DataCake IoT Server
	326
	327	[[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:
	328
	329
	330	Step 1: Be sure that your device is programmed and properly connected to the network at this time.
	331
	332	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:

	703
	704	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.
	705
	706
	707	The battery is designed to last for more than 5 years for the LSN50.
	708
	709

4.2	726	111. Battery Note
	727
	728	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	733	111. Replace the battery
	734
	735	If Battery is lower than 2.7v, user should replace the battery of LSE01.
	736
	737
	738	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.
	739
	740
	741	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)

	884	When downloading the images, choose the required image file for download.
	885
	886
8.3	887	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	888
	889
	890	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.
	891
	892
	893	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.
	894
8.2	895	[[image:image-20220606154726-3.png]]
4.2	896
	897	When you use the TTN network, the US915 frequency bands use are:
	898
	899	* 903.9 - SF7BW125 to SF10BW125
	900	* 904.1 - SF7BW125 to SF10BW125
	901	* 904.3 - SF7BW125 to SF10BW125
	902	* 904.5 - SF7BW125 to SF10BW125
	903	* 904.7 - SF7BW125 to SF10BW125
	904	* 904.9 - SF7BW125 to SF10BW125
	905	* 905.1 - SF7BW125 to SF10BW125
	906	* 905.3 - SF7BW125 to SF10BW125
	907	* 904.6 - SF8BW500
	908
	909	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:
	910
8.3	911	(% class="box infomessage" %)
	912	(((
4.2	913	AT+CHE=2
8.3	914	)))
4.2	915
8.3	916	(% class="box infomessage" %)
	917	(((
4.2	918	ATZ
8.3	919	)))
4.2	920
	921	to set the end node to work in 8 channel mode. The device will work in Channel 8-15 & 64-71 for OTAA, and channel 8-15 for Uplink.
	922
	923
	924	The AU915 band is similar. Below are the AU915 Uplink Channels.
