81 == 2.1 How it works ==
82
83 (((
84 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
85 )))
86
87 (((
88 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"]].

93 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
94
95 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
97
98 [[image:1654503992078-669.png]]
99
100
101 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.
102
103
104 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
105
106 Each LSE01 is shipped with a sticker with the default device EUI as below:
107
108 [[image:image-20220606163732-6.jpeg]]
109
110 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

125 **Step 2**: Power on LSE01
126
127
128 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
129
130 [[image:image-20220606163915-7.png]]
131
132
133 **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.

200
201 === 2.3.4 Soil Moisture ===
202
203 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.
204
205 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
206
207
208 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
209
210
211
212 === 2.3.5 Soil Temperature ===
213
214 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
215
216 **Example**:
217
218 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
219
220 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C
221
222
223
224 === 2.3.6 Soil Conductivity (EC) ===
225
226 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).
227
228 For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
229
230
231 Generally, the EC value of irrigation water is less than 800uS / cm.

283
284 **Examples**
285
286
287 **Set TDC**
288
289 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
290
291 Payload:    01 00 00 1E    TDC=30S

707 111. ​Battery Note
708
709 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.

714 111. ​Replace the battery
715
716 If Battery is lower than 2.7v, user should replace the battery of LSE01.
717
718
719 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.
720
721
722 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)

867
868 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.
869
870
871 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.
872
873
874 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.
875
876 [[image:image-20220606154726-3.png]]
877
878 When you use the TTN network, the US915 frequency bands use are:
879
880 * 903.9 - SF7BW125 to SF10BW125
881 * 904.1 - SF7BW125 to SF10BW125
882 * 904.3 - SF7BW125 to SF10BW125
883 * 904.5 - SF7BW125 to SF10BW125
884 * 904.7 - SF7BW125 to SF10BW125
885 * 904.9 - SF7BW125 to SF10BW125
886 * 905.1 - SF7BW125 to SF10BW125
887 * 905.3 - SF7BW125 to SF10BW125
888 * 904.6 - SF8BW500
889
890 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:
891
892 (% class="box infomessage" %)
893 (((
894 **AT+CHE=2**
895 )))
896
897 (% class="box infomessage" %)
898 (((
899 **ATZ**
900 )))
901
902 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.
903
904
905 The **AU915** band is similar. Below are the AU915 Uplink Channels.

913 == 5.1 ​Why I can’t join TTN in US915 / AU915 bands? ==
