14
15 (((
16 The Dragino LSE01 is a (% style="color:#4f81bd" %)**LoRaWAN Soil Moisture & EC Sensor**(%%) for IoT of Agriculture. It is designed to measure the soil moisture of saline-alkali soil and loamy soil. The soil sensor uses FDR method to calculate the soil moisture with the compensation from soil temperature and conductivity. It also has been calibrated in factory for Mineral soil type.

19 (((
20 It detects (% style="color:#4f81bd" %)**Soil Moisture**(%%), (% style="color:#4f81bd" %)**Soil Temperature**(%%) and (% style="color:#4f81bd" %)**Soil Conductivity**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
21 )))
22
23 (((
24 The LoRa wireless technology used in LES01 allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.

26
27 (((
28 LES01 is powered by (% style="color:#4f81bd" %)**4000mA or 8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to 10 years.
29 )))
30
31 (((
32 Each LES01 is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

83 == 2.1 How it works ==
84
85 (((
86 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
87 )))
88
89 (((
90 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"]].

94
95 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
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.
98
99
100 [[image:1654503992078-669.png]]
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
110 [[image:image-20220606163732-6.jpeg]]
111
112 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

125
126
127 **Step 2**: Power on LSE01
128
129
130 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
131
132 [[image:image-20220606163915-7.png]]
133
134
135 **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.

203 === 2.3.4 Soil Moisture ===
204
205 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.
206
207 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
208
209
210 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
211
212
213
214 === 2.3.5 Soil Temperature ===
215
216 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
217
218 **Example**:
219
220 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C

249
250 Firmware version at least v2.1 supports changing mode.

252 For example, bytes[10]=90
253
254 mod=(bytes[10]>>7)&0x01=1.

261 If** **payload =** **0x0A01, workmode=1
262
263
264
265 === 2.3.8 ​Decode payload in The Things Network ===
266
267 While using TTN network, you can add the payload format to decode the payload.
268
269
270 [[image:1654505570700-128.png]]
271
272 The payload decoder function for TTN is here:

275
276
277 == 2.4 Uplink Interval ==
278
279 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:
280
281 [[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]]
282
283
284
285 == 2.5 Downlink Payload ==
286
287 By default, LSE50 prints the downlink payload to console port.
288
289 [[image:image-20220606165544-8.png]]
290
291
292 **Examples:**
293
294
295 * **Set TDC**
296
297 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
298
299 Payload:    01 00 00 1E    TDC=30S
300
301 Payload:    01 00 00 3C    TDC=60S
302
303
304 * **Reset**
305
306 If payload = 0x04FF, it will reset the LSE01
307
308
309 * **CFM**
310
311 Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0
312
313
314
315 == 2.6 ​Show Data in DataCake IoT Server ==
316
317 [[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:
318
319
320 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
321
322 **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:
323
324
325 [[image:1654505857935-743.png]]
326
327
328 [[image:1654505874829-548.png]]
329
330 Step 3: Create an account or log in Datacake.
331
332 Step 4: Search the LSE01 and add DevEUI.
333
334
335 [[image:1654505905236-553.png]]
336
337
338 After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.

881 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.
882
883
884 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.
885
886
887 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.
888
889 [[image:image-20220606154726-3.png]]
890
891 When you use the TTN network, the US915 frequency bands use are:
892
893 * 903.9 - SF7BW125 to SF10BW125
894 * 904.1 - SF7BW125 to SF10BW125
895 * 904.3 - SF7BW125 to SF10BW125
896 * 904.5 - SF7BW125 to SF10BW125
897 * 904.7 - SF7BW125 to SF10BW125
898 * 904.9 - SF7BW125 to SF10BW125
899 * 905.1 - SF7BW125 to SF10BW125
900 * 905.3 - SF7BW125 to SF10BW125
901 * 904.6 - SF8BW500
902
903 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:
904
905 (% class="box infomessage" %)
906 (((
907 **AT+CHE=2**
908 )))
909
910 (% class="box infomessage" %)
911 (((
912 **ATZ**
913 )))
914
915 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.
916
917
918 The **AU915** band is similar. Below are the AU915 Uplink Channels.
