Xiaoling 15.3 87 (((
Xiaoling 4.2 88 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

Xiaoling 4.2 98
99 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.

Xiaoling 4.2 103
104
105 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.
106
107
108 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
109
110 Each LSE01 is shipped with a sticker with the default device EUI as below:

137 **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.

Xiaoling 8.3 883 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.
Xiaoling 4.2 884
885
886 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.
887
888
889 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.

Xiaoling 4.2 892
893 When you use the TTN network, the US915 frequency bands use are:
894
895 * 903.9 - SF7BW125 to SF10BW125
896 * 904.1 - SF7BW125 to SF10BW125
897 * 904.3 - SF7BW125 to SF10BW125
898 * 904.5 - SF7BW125 to SF10BW125
899 * 904.7 - SF7BW125 to SF10BW125
900 * 904.9 - SF7BW125 to SF10BW125
901 * 905.1 - SF7BW125 to SF10BW125
902 * 905.3 - SF7BW125 to SF10BW125
903 * 904.6 - SF8BW500
904
905 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:

929
Xiaoling 4.11 930 It is due to channel mapping. Please see the [[Eight Channel Mode>>doc:Main.LoRaWAN Communication Debug.WebHome||anchor="H2.NoticeofUS9152FCN4702FAU915Frequencyband"]] section above for details.

Xiaoling 4.2 946
947 The fuse on LSE01 is not large enough, some of the soil probe require large current up to 5v 800mA, in a short pulse. When this happen, it cause the device reboot so user see rejoin.
