	312	+This section shows an example for how to join the [[TheThingsNetwork>>url:https://www.thethingsnetwork.org/]] LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are of similar procedure.

	314	+
	315	+Assume the DLOS8 is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the AIS Sensor device in TTN V3 portal.
	316	+
	317	+**Step 1**:  Create a device in TTN V3 with the OTAA keys from AIS Sensor.
	318	+
	319	+Each AIS Sensor is shipped with a sticker with the default DEV EUI as below:
	320	+
	321	+[[image:image-20230426083617-1.png||height="294" width="633"]]
	322	+
	323	+Enter these keys in the LoRaWAN Server portal. Below is TTN V3 screen shot:
	324	+
	325	+Add APP EUI in the application.
	326	+
	327	+choose to create the device manually.
	328	+
	329	+Add APP KEY and DEV EUI

	341	+
	342	+**Step 2**:  Use ACT button to activate LHT52 and it will auto join to the TTN V3 network. After join success, it will start to upload sensor data to TTN V3 and user can see in the panel.

	346	+The uplink payload includes totally 14 bytes. Uplink packets use FPORT=5 and (% style="color:#4472c4" %)**every 20 minutes**(%%) send one uplink by default.

	357	+
	358	+These two bytes of BAT include the battery state and the actual voltage.

	361	+
	362	+=== 3.1.3 sysTimeCurrent ===
	363	+
	364	+These four bytes contain the year, month, day, hour, minute, and second of the time.
	365	+
	366	+AI Sensor use Unix TimeStamp format based on
