== 2.1 How it works? ==

128

129

130

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 ==

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.

138

139

140

[[image:1664501652064-326.png]]

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:

145

146

147

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

148

149

Each TrackerD is shipped with a sticker with the default device EUI as below:

WiFiMASK is to filter the unwanted WiFi SSID during scan. For example, if WiFiMASK is 123456. TrackerD will only uplink SSID info which includes 123456 as prefix. It will ignore all other WiFi which doesn’t contact 123456 in the SSID.

User can use the TrackerD's USB port to upgrade firmware into it. The hardware connection for upgrade firmware is as below:

1005

1006

1007

(% style="color:blue" %)**Step1: **(%%)Connect TrackerD and PC via USB cable shipped with TrackerD.

1008

1010

(% style="color:blue" %)**Step2:** (%%) Install CH9102 driver in the PC.

1011

1012

After installation of the driver and plug in TrackerD, user should be able to see com port in PC's device manager.

== 7.3 Notes on using different serial port tools for TrackerD ==

1144

1145

1146

=== 7.3.1 Serial port utility ===

1147

1148

1149

Serial port utility requires you to automatically add data streams.

1150

1151

Need to adjust the data stream to RTS/CTS on physical restart.

1155

[[image:image-20221102140621-1.png]]

1156

1157

1158

When using AT commands, the data flow needs to be adjusted to XON/XOFF

1159

=== 7.3.2 SecureCRT ===

1166

1167

== 8.1 TDC is changed to 4294947296 and cause no uplink. ==

(((

Before firmware v1.4.0: When the Transport Mode is enabled (**AT+INTWK=1**), the **TDC** needs to be greater than **MTDC**, otherwise, TDC setting will because 4294947296 after wakre up from motion. This bug is fixed in firmware v1.4.1

)))

== 8.2 Device not able get AT Command or show output after wake up from deep sleep mode ==

(((

ESP32 is not able to accept the Interrupt from UART after wake up from deep sleep mode. User need to press the button (one click) and trackerD will be able to accept UART command, it there is no action in UART for 15 seconds. it will go to deep sleep mode.

)))

== 8.3 The reason why it has been restarted after upgrading（V.1.4.1） ==

(((

If it is V1.4.0 and the previous version, new partitions need to be loaded when upgrading. The new version of the software is stored in the partition package. The upgrade method is shown in the figure

1222

1223

== 8.4 If the device's led light is always on when upgrading（since firmware 1.4.1） ==

1224

It is because the partitions are different when upgrading versions above 1.4.1, and a new partition file needs to be added. Please refer to the operation steps in chapter 8.3.
