== 2.1 How it works? ==

131

132

133

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 ==

138

139

140

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.

141

142

143

[[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:

148

149

150

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

151

152

Each TrackerD is shipped with a sticker with the default device EUI as below:

153

154

155

184

185

186

(% style="color:blue" %)**Step 3:**(%%) TrackerD will auto join to the LoRaWAN network. After join success, TrackerD will start to upload message to IoT server.

== 2.3 Positioning Mode(SMOD) ==

191

192

193

Users can set TrackerD to different Positioning Mode for different applications. Below mod are supported.

194

195

* (% style="color:#037691" %)**GPS ONLY(Factory Settings): **(%%)only get and uplink GPS location info.

196
