301
Xiaoling 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.

307
Xiaoling 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.

Xiaoling 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
Xiaoling 123.2 316 Step 1: Create a device in TTN with the OTAA keys from PS-LB/LS.
Xiaoling 6.2 317

Mengting Qiu 93.1 623 There are two ways to set the device's time:
624
625
Xiaoling 123.2 626 ~1. Through LoRaWAN MAC Command (Default settings)
Mengting Qiu 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
Xiaoling 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.
Mengting Qiu 93.1 633

Xiaoling 123.2 635 2. Manually Set Time
Mengting Qiu 93.1 636
