79
80 == 2.1 How it works ==
81
82 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
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 >>path:#_​Using_the_AT]]to set the keys in the LSE01.

91 11. ​Quick guide to connect to LoRaWAN server (OTAA)
92
93 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.

96 [[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image003.png]]
97
98
99 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.
100
101
102 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
103
104 Each LSE01 is shipped with a sticker with the default device EUI as below:
105
106
107
108
109 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

140
141
142
143
144
145 **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.

205 111. Battery Info
206
207 Check the battery voltage for LSE01.
208
209 Ex1: 0x0B45 = 2885mV
210
211 Ex2: 0x0B49 = 2889mV
212
213
214
215 1.
216 11.
217 111. Soil Moisture
218
219 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.
220
221 For example, if the data you get from the register is 0x05 0xDC, the moisture content in the soil is
222
223 **05DC(H) = 1500(D) /100 = 15%.**
224
225
226 1.
227 11.
228 111. Soil Temperature
229
230 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
231
232 **Example**:
233
234 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
235
236 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C
237
238
239 1.
240 11.
241 111. Soil Conductivity (EC)
242
243 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).
244
245 For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
246
247
248 Generally, the EC value of irrigation water is less than 800uS / cm.
249

724 111. ​Battery Note
725
726 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.

731 111. ​Replace the battery
732
733 If Battery is lower than 2.7v, user should replace the battery of LSE01.
734
735
736 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.
737
738
739 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)

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