29 (((
30 TrackerD-LS is an (% style="color:blue" %)**Open Source LoRaWAN Asset Tracker**(%%) based on (% style="color:blue" %)**ESP32 MCU**(%%) and (% style="color:blue" %)**Semtech LoRa Wireless Chip**(%%). It can get the location data via GPS and set it to IoT server via LoRaWAN network.
31
32 TrackerD-LS supports Motion Detection, when there is motion, TrackerD-LS can send data more frequently and it will save power when no motion is detected.
33
34 The LoRa wireless technology used in TrackerD-LS 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.
35
36 When there is no LoRaWAN network, TrackerD-LS can save the location data. It will send these data to IoT server when there is LoRaWAN network coverage.
37
38 TrackerD-LS is equipped with a (% style="color:blue" %)**3000mAh Li-ion rechargeable battery + Solar Panel**(%%) which let the device can be used for many years. Each TrackerD-LS has a worldwide unique OTAA keys to join the LoRaWAN network.
39
40 TrackerD-LS is program friendly. Developers can use Arduino IDE to customize the software of TrackerD-LS to fit their IoT solution.

151
152 == 2.1 How it works? ==
153
154
155 TrackerD-LS 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-LS (next to USB port). TrackerD-LS will wake up and auto join the network via OTAA.
156
157
158 == 2.2 Quick guide to connect to LoRaWAN server ==
159
160
161 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. 
162
163 [[image:image-20250321141547-2.png]]
164
165
166 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:
167
168
169 (% style="color:blue" %)**Step 1**:(%%) Create a device in TTN V3 with the OTAA keys from TrackerD-LS.
170

587 There are two ways to put the device into sleep mode:
588
589 ~1. Quickly press the device 5 times to enter deep sleep.
590
591 2. Use the AT+SLEEP command to put the device into sleep.

600
601 **Mode 1: connected via a dedicated 4Pin cable**
602
603 [[image:image-20250414165011-3.png||height="353" width="843"]]

609
610 (% style="color:red" %)**Note: Because the serial port also comes with a charging function, when using the newly added external charging, you can't use the serial port for connection at the same time, otherwise the mother board will not be able to withstand the voltage and burn the base board.**

951 == 4.2 How to upgrade firmware ==
952
953
954 User can use the TrackerD-LS's USB port to upgrade firmware into it. The hardware connection for upgrade firmware is as below:
955
956
957 **Step 1:** Connect the TrackerD-LS to the PC via the USB cable that came with the TrackerD-LS or the dedicated 4Pin cable.
958
959 Mode 1: connected via TYPE-C
960
961 [[image:image-20250326102040-2.jpeg||height="516" width="458"]]
962
963

965
966 [[image:image-20250326173255-2.png]]
967
968
969 **Step2:**  Install CH9102 driver in the PC.
970
971 After installation of the driver and plug in TrackerD-LS, user should be able to see com port in PC's device manager.
