➢ Power LED: This RED LED will be solid if the device is properly powered

➢ ETH LED:   This RGB LED will blink GREEN when the ETH port is connecting

➢ SYS LED:   This RGB LED will show different colors in different states:

                     ✓ SOLID GREEN: The device is alive with a LoRaWAN server connection.

                     ✓ BLINKING GREEN: a) Device has internet connection but no LoRaWAN Connection. or b) Device is in booting stage, in this stage, it will BLINKING GREEN for several seconds and then with BLINKING GREEN together

                     ✓ SOLID RED: Device doesn't have an Internet connection.

➢ WIFI LED: This LED shows the WIFI interface connection status.

1.6 Button Intruction

LG01-V2 has a black toggle button, which is:

➢ Long press 4-5s                   : the gateway will reload the Network and Initialize wifi configuration

                                                      LED status:  ETH LED will BLINKIND BULE Until the reload is finished.

➢ Long press more than 10s:    the gateway will restore the factory settings.

                                                     LED status:  ETH LED will SOLID BULE Until the restore is finished.

2. Quick Start

The LG01-V2 supports network access via Ethernet or Wi-Fi connection and runs without a network.

In most cases, the first thing you need to do is make the LG01-v2 accessible to the network.

2.1 Connects to the network and accesses the gateway Web UI

2.1.1 connect the network.

Method 1:  Connect via Ethernet with DHCP IP from the router

Connect the LG01-V2 Ethernet port to your router and LG01-V2 can obtain an IP address from your router. In the router's management portal, you should be able to find what IP address the router has assigned to the LG01-V2.

You can also use this IP to connect.

4. Build in Server

The default factory version of LG01-V2 is installed with the built-in Applicant server: Node-Red

image-20221104155949-6.png

Note:

         Path: System --> Built-in Server

Troubleshooting:

         1. URL does not jump properly

                For the Node-Red, you can use the local IP address and the port is 1880 to access it.

4.1 Application Server -- Node-Red

You can access the gateway's built-in AS server of Node-Red via the URL(http://<hostname>:1880 or http://<local-IPV4-address>) in your browser.

Such as http://dragino-54ff12:1880  or http://<Local-IPV4-Address>

5. How to configure the Lora Gateway

5.1 Access the Lora configuration page

Users can access the Lora configuration page by running the following command, then select the option ''serial port setup":

root@dragino-2406ef:~# minicom -s

image-20221029174637-2.png

And then, change the setting:

Serial Device : /dev/ttyUSB0

Bps/Par/Bits : 9600 8N1

Note: Enter the corresponding letter to change the configuration, like A,B,C
image-20221029174703-3.png
