	300
	301
123.2	302	The PS-LB/LS is configured as 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 activate the PS-LB/LS. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.

26.2	305	== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
	306
	307
6.2	308	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.

26.2	310	[[image:1675144005218-297.png]]
6.2	311
	312
	313	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.
	314
	315
123.2	316	Step 1: Create a device in TTN with the OTAA keys from PS-LB/LS.
6.2	317
72.8	318	Each PS-LB/LS is shipped with a sticker with the default device EUI as below:

	348
72.8	349	Press the button for 5 seconds to activate the PS-LB/LS.
6.2	350
123.2	351	Green led will fast blink 5 times, device will enter OTA mode for 3 seconds. And then start to JOIN LoRaWAN network. Green led will solidly turn on for 5 seconds after joined in network.
6.2	352

	624
	625
123.2	626	~1. Through LoRaWAN MAC Command (Default settings)
93.1	627
	628	Users need to set SYNCMOD=1 to enable sync time via the MAC command.
	629
	630	Once CPL01 Joined the LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to CPL01. If CPL01 fails to get the time from the server, CPL01 will use the internal time and wait for the next time request ~[[[via Device Status (FPORT=5)>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/CPL01%20LoRaWAN%20Outdoor%20PulseContact%20%20Sensor%20Manual/#H2.3.1DeviceStatus2CFPORT3D5]]].
	631
123.2	632	Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.
93.1	633
	634
123.2	635	2. Manually Set Time
93.1	636
