78 == 2.1 How it works ==
79
80 (((
81 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
82 )))
83
84 (((
85 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 >>||anchor="H3.​UsingtheATCommands"]].

90 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
91
92 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.
93
94
95 [[image:1654503992078-669.png]]
96
97
98 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.
99
100
101 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
102
103 Each LSE01 is shipped with a sticker with the default device EUI as below:
104
105

204 111. Battery Info
205
206 Check the battery voltage for LSE01.
207
208 Ex1: 0x0B45 = 2885mV
209
210 Ex2: 0x0B49 = 2889mV

214 1.
215 11.
216 111. Soil Moisture
217
218 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.
219
220 For example, if the data you get from the register is 0x05 0xDC, the moisture content in the soil is
221
222 **05DC(H) = 1500(D) /100 = 15%.**
223
224
225 1.
226 11.
227 111. Soil Temperature
228
229 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
230
231 **Example**:
232
233 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
234
235 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C
236
237
238 1.
239 11.
240 111. Soil Conductivity (EC)
241
242 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).
243
244 For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
245
246
247 Generally, the EC value of irrigation water is less than 800uS / cm.
248

723 111. ​Battery Note
724
725 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.

730 111. ​Replace the battery
731
732 If Battery is lower than 2.7v, user should replace the battery of LSE01.
733
734
735 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.
736
737
738 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)

883
884 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.
885
886
887 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.
888
889
890 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.
891
892 [[image:image-20220606154726-3.png]]
893
894 When you use the TTN network, the US915 frequency bands use are:
895
896 * 903.9 - SF7BW125 to SF10BW125
897 * 904.1 - SF7BW125 to SF10BW125
898 * 904.3 - SF7BW125 to SF10BW125
899 * 904.5 - SF7BW125 to SF10BW125
900 * 904.7 - SF7BW125 to SF10BW125
901 * 904.9 - SF7BW125 to SF10BW125
902 * 905.1 - SF7BW125 to SF10BW125
903 * 905.3 - SF7BW125 to SF10BW125
904 * 904.6 - SF8BW500
905
906 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:
907
908 (% class="box infomessage" %)
909 (((
910 **AT+CHE=2**
911 )))
912
913 (% class="box infomessage" %)
914 (((
915 **ATZ**
916 )))
917
918 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.
919
920
921 The **AU915** band is similar. Below are the AU915 Uplink Channels.
