== 2.1 How it works? ==

130

131

132

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 ==

137

138

139

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.

140

141

142

[[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:

147

148

149

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

150

151

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

152

153

154

[[image:1664501677253-891.png]]

155

(% 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.

186

187

188

== 2.3 Positioning Mode(SMOD) ==

189

190

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

191

192

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

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

194

* (% 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.
