== 2.1 How it works? ==

126

127

128

TrackerD is configured as LoRaWAN OTAA Class A GPS tracker by default. It has OTAA keys to join LoRaWAN network. To connect a LoRaWAN network, user need to input the OTAA keys in the LoRaWAN IoT server and push reset button of TrackerD (next to USB port). TrackerD will wake up and auto join the network via OTAA.

== 2.2 Quick guide to connect to LoRaWAN server ==

133

134

135

Here is an example for how to join the [[TTNv3 LoRaWAN Network>>url:https://eu1.cloud.thethings.network]]. Below is the network structure, we use LPS8N as LoRaWAN gateway in this example.

136

137

138

[[image:1664501652064-326.png]]

The LPS8N is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. What the rest need to is register this device in TTN V3:

143

144

145

(% style="color:blue" %)**Step 1**:(%%) Create a device in TTN V3 with the OTAA keys from TrackerD.

146

User can push the **RED button** by more than 5 seconds to enter Alarm Mode.

399

400

401

Once enter Alarm mode, the **GREEN LED** will flash 3 times, the buzzer will alarm for 5 seconds, then TrackerD will immediately send a packet without location info and then send a data packet with GPS positioning information. After that, the device will send 60 packets at 1-minute intervals. The Alarm flag in the payload will be set for the next 60 packets unless exit alert mode.

402

403

404

Two ways to exit alarm mode:

405

406

* Server send a downlink command to exit.

407

* User fast press the RED button 10 times.

408

409

When exit alarm mode, **RED LED** will light up for 5 seconds, indicating that the alarm mode is exited. And the alert flag will be set to false.

622

623

运动模式：设备入网后会发送device当前模式下的信息，随后发送GPS定位数据，设备判断是否在运动，没有运动传感器没有检测到动作，立即进入静止状态（默认20分钟），如果产生运动，将每5分钟发送一次数据，再第五分钟后检测设备有误运动，无将切换到静止状态，有立即发送数据。

673

674

675

A GPS packet with lower PDOP has higher accuracy. PDOP default value is 2.0
