4.2	101
	102	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.

15.2	105	[[image:1654503992078-669.png]]
4.2	106
	107
	108	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.
	109
	110
	111	Step 1: Create a device in TTN with the OTAA keys from LSE01.
	112
	113	Each LSE01 is shipped with a sticker with the default device EUI as below:
	114

	351
	352	Step 1: Be sure that your device is programmed and properly connected to the network at this time.
	353
	354	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:
