It will automatically join the network via OTAA and start to send the sensor value

4.2	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.

	97
15.2	98	[[image:1654503992078-669.png]]
4.2	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
17.2	108	[[image:image-20220606163732-6.jpeg]]

	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:

	693
	694	The LSE01 battery is a combination of a 4000mAh Li/SOCI2 Battery and a Super Capacitor. The battery is non-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.
	695
	696
	697	The battery is designed to last for more than 5 years for the LSN50.
	698

4.2	716	111. Battery Note
	717
	718	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.

4.2	723	111. Replace the battery
	724
	725	If Battery is lower than 2.7v, user should replace the battery of LSE01.
	726
	727
	728	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.
	729
	730
	731	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)

	874	When downloading the images, choose the required image file for download.
	875
	876
8.3	877	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.
4.2	878
	879
	880	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.
	881
	882
	883	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.
	884
8.2	885	[[image:image-20220606154726-3.png]]
4.2	886
	887	When you use the TTN network, the US915 frequency bands use are:
	888
	889	* 903.9 - SF7BW125 to SF10BW125
	890	* 904.1 - SF7BW125 to SF10BW125
	891	* 904.3 - SF7BW125 to SF10BW125
	892	* 904.5 - SF7BW125 to SF10BW125
	893	* 904.7 - SF7BW125 to SF10BW125
	894	* 904.9 - SF7BW125 to SF10BW125
	895	* 905.1 - SF7BW125 to SF10BW125
	896	* 905.3 - SF7BW125 to SF10BW125
	897	* 904.6 - SF8BW500
	898
	899	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:
	900
8.3	901	(% class="box infomessage" %)
	902	(((
4.2	903	AT+CHE=2
8.3	904	)))
4.2	905
8.3	906	(% class="box infomessage" %)
	907	(((
4.2	908	ATZ
8.3	909	)))
4.2	910
	911	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.
	912
	913
	914	The AU915 band is similar. Below are the AU915 Uplink Channels.
