== 2.1 How it works? ==

129

130

131

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.

132

133

134

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

135

136

137

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.
