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.
17 )))

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.
25 )))
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.

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"]].

92
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]]

123
124
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.

708 111. ​Battery Note
709
710 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.

715 111. ​Replace the battery
716
717 If Battery is lower than 2.7v, user should replace the battery of LSE01.
718
719
720 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.
721
722
723 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)

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

913
914 == 5.1 ​Why I can’t join TTN in US915 / AU915 bands? ==
