== 2.1 How it works? ==

137

138

139

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 ==

144

145

146

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.

147

148

149

[[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:

154

155

156

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

157

158

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

159

160

161

[[image:1664501677253-891.png]]

162

163

164

Input these keys to their LoRaWAN Server portal. Below is TTN V3 screen shot:

190

191

192

(% 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.

193

194

195

== 2.3 Positioning Mode(SMOD) ==

196

197

198

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

199

200

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

201

* (% style="color:#037691" %)**BLE ONLY: **(%%)Only obtain iBeacon info via BLE and uplink. Design for Indoor tracking.

202

* (% style="color:#037691" %)**GPS/BLE Hybrid: **(%%)Combination for Indoor and Outdoor tracking.Devices will try to search BLE iBeacon first. If device can't find the iBeacon, it will use GPS for positioning.

203

204

Users can switch modes by [[changing SMOD>>||anchor="H3.2.7SetPositioningMode"]].
