	100	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.

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