18 In TrackerD, there are various sensors such as GPS, WiFi, BLE, Temperature, Humidity, Motion Detection, and Buzzer. User can use TrackerD for different tracking scenario.
19
20 TrackerD is program friendly. Developers can use Arduino IDE to customize the software of TrackerD to fit their IoT solution.
21
22 The LoRa wireless technology used in TrackerD allows the user to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional tracking services.

123 1. Use TrackerD
124 11. How it works?
125
126
127 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.

131 11. Quick guide to connect to LoRaWAN server
132
133 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.
134
135
136 [[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image001.png]]
137
138
139 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:
140
141 **Step 1**: Create a device in TTN V3 with the OTAA keys from TrackerD.
142
143 Each TrackerD is shipped with a sticker with the default device EUI as below:
144
145 [[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image002.png]]
146
147
148
149
150 Input these keys to their LoRaWAN Server portal. Below is TTN V3 screen shot:
151
152
153 Add APP EUI in the application

167
168
169
170
171 **Step 2**: Power on TrackerD by using the on board switch.
172
173
174 **Step 3:** TrackerD will auto join to the LoRaWAN network. After join success, TrackerD will start to upload message to IoT server.
175
176
177 **Positioning Mode(SMOD):**
178
179 * **GPS ONLY(Factory Settings): **only get GPS location info.
180 * **BLE ONLY: **Only obtain iBeacon info via BLE. Design for Indoor tracking.
181 * **GPS/BLE Hybrid: **Combination for Indoor and Outdoor tracking.
182
183 User can switch modes by [[changing SMOD>>path:#Positioning_Mode]].

254 1. When power is low (<2.84v), GPS won’t be able to get location info and GPS feature will be disabled and the location field will be filled with 0x0FFFFFFF, 0x0FFFFFFF.
255 1. In firmware version v1.5, Roll & Pitch is disabled by default.
256 1. When enable 9-axis motion sensor, the total payload will be 15 bytes, while US915/AU915 DR0 accept only 11 bytes payload. In this case, the payload on server will be ignore and shows as below:

391
392
393 User can push the **RED button** by more than 5 seconds to enter Alarm Mode.
394
395
396 Once enter Alarm mode, the **GREEN LED** will flash 3 times, the buzzer will alarm for 5 seconds, then TrackerD will immediately send a packet without location info and then send a data packet with GPS positioning information. After that, the device will send 60 packets at 1-minute intervals. The Alarm flag in the payload will be set for the next 60 packets unless exit alert mode.
397
398
399 Two ways to exit alarm mode:
400
401 * Server send a downlink command to exit.
402 * User fast press the RED button 10 times.
403
404 When exit alarm mode, **RED LED** will light up for 5 seconds, indicating that the alarm mode is exited. And the alert flag will be set to false.

675
676
677 A GPS packet with lower PDOP has higher accuracy. PDOP default value is 2.0

726 11. How to upgrade firmware
727
728 User can use the TrackerD ’s USB port to upgrade firmware into it. The hardware connection for upgrade firmware is as below:
729
730
731 **Step1:  **Connect TrackerD and PC via USB cable shipped with TrackerD.
732
733 **Step2:**  Install CH9102 driver in the PC.
734
735 After installation of the driver and plug in TrackerD, user should be able to see com port in PC's device manager.
736
737
738 **Step3：** Download and Install Flash Tool:
739
740 [[https:~~/~~/www.espressif.com.cn/en/support/download/other-tools?keys=Flash%2BDownload%2BTools>>url:https://www.espressif.com.cn/en/support/download/other-tools?keys=Flash%2BDownload%2BTools]]
741
742 **Step4:**  Run Flash Download Tool and configure chip type to ESP32
