	199	+The LTC2-LB is configured as (% style="color:#037691" %)**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 press the button to activate the LTC2-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is **20 minutes**.

	210	+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 [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
	211	+
	212	+The LPS8V2 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.

	218	+
	219	+Each LTC2-LB is shipped with a sticker with the default device EUI as below:

	262	+Press the button for 5 seconds to activate the LTC2-LB.
	263	+
	264	+(% style="color:green" %)**Green led**(%%) will fast blink 5 times, device will enter (% style="color:blue" %)**OTA mode**(%%) for 3 seconds. And then start to JOIN LoRaWAN network. (% style="color:green" %)**Green led**(%%) will solidly turn on for 5 seconds after joined in network.
	265	+
	266	+After join success, it will start to upload messages to TTN and you can see the messages in the panel.
