133 == 2.1 How it works? ==
134
135
136 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.
137

139
140 == 2.2 Quick guide to connect to LoRaWAN server ==
141
142
143 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
150 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:
151
152
153 (% style="color:blue" %)**Step 1**:(%%) Create a device in TTN V3 with the OTAA keys from TrackerD.
154
155 Each TrackerD is shipped with a sticker with the default device EUI as below:
156
157
158 [[image:1664501677253-891.png]]

466 TrackerD supports BLE scans for indoor positioning. User can set [[**SMOD**>>||anchor="H3.2.7SetPositioningMode"]] to **BLE pure** or **GPS/BLE hybrid** so TrackerD will scan BLE iBeacon and find the strongest iBeacon info and uplink.
467
468 User can set **[[BLEMASK>>||anchor="H3.2.11A0SetBLEMASKtofilterBLEiBeacon"]]** so TrackerD will only search the iBeacons which have UUID that match the BLEMASK settings.

914 BLEMASK is to filter the unwanted BLE iBeacons during scan. For example, if BLEMASK is 123456. LBT1 will only uplink UUID info which includes 123456. It will ignore all other iBeacons which doesn’t contact 123456 in the UUID.

947
948 User can use the TrackerD's USB port to upgrade firmware into it. The hardware connection for upgrade firmware is as below:
949
950
951 (% style="color:blue" %)**Step1:  **(%%)Connect TrackerD and PC via USB cable shipped with TrackerD.
952
953
954 (% style="color:blue" %)**Step2:** (%%) Install CH9102 driver in the PC.
955
956 After installation of the driver and plug in TrackerD, user should be able to see com port in PC's device manager.
