== 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

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:

149

150

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

657

658

659

Set max positioning time, default is 150 seconds. TrackerD will try to get location info within this period. If fail to get position data within this time, TrackerD will use 000000 for latitude and longitude.

660

661

662

If AT+FTIME=0. The GPS module will be always powered and positioning. This will highly increase the power consumption (up to 50mA). When AT+FTIME=0, it will improve fix accuracy and shorten the acquire time for next uplink.

663

679

680

681

PDOP(Position Dilution of Precision) filter, TrackerD will only accept GPS data with a lower PDOP value than pre-configure PDOP value. If device can't get a valid GPS packet within FTIME timeout, it will use the GPS data with lowest PDOP value to server.

682

683

684

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