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]]

	313	== 2.6 Show Data in DataCake IoT Server ==
	314
4.2	315	[[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:
	316
	317
	318	Step 1: Be sure that your device is programmed and properly connected to the network at this time.
	319
	320	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:

	669
	670	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.
	671
	672
	673	The battery is designed to last for more than 5 years for the LSN50.

4.2	692	111. Battery Note
	693
	694	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	699	111. Replace the battery
	700
	701	If Battery is lower than 2.7v, user should replace the battery of LSE01.
	702
	703
	704	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.
	705
	706
	707	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)

	850	When downloading the images, choose the required image file for download.
	851
	852
8.3	853	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	854
	855
	856	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.
	857
	858
	859	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.
	860
8.2	861	[[image:image-20220606154726-3.png]]
4.2	862
	863	When you use the TTN network, the US915 frequency bands use are:
	864
	865	* 903.9 - SF7BW125 to SF10BW125
	866	* 904.1 - SF7BW125 to SF10BW125
	867	* 904.3 - SF7BW125 to SF10BW125
	868	* 904.5 - SF7BW125 to SF10BW125
	869	* 904.7 - SF7BW125 to SF10BW125
	870	* 904.9 - SF7BW125 to SF10BW125
	871	* 905.1 - SF7BW125 to SF10BW125
	872	* 905.3 - SF7BW125 to SF10BW125
	873	* 904.6 - SF8BW500
	874
	875	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:
	876
8.3	877	(% class="box infomessage" %)
	878	(((
4.2	879	AT+CHE=2
8.3	880	)))
4.2	881
8.3	882	(% class="box infomessage" %)
	883	(((
4.2	884	ATZ
8.3	885	)))
4.2	886
	887	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.
	888
	889
	890	The AU915 band is similar. Below are the AU915 Uplink Channels.
