1. Introduction

1.1 What is LG01v2

The LG01v2 is an open-source single channel LoRa Gateway. It lets you bridge LoRa wireless network to an IP network via WiFi , Ethernet or Cellular Network (via Optional 4G module). The LoRa wireless allows users to send data and reach extremely long ranges at low data rates.

LG01v2 is specially designed for peer-to-peer LoRa protocol instead of LoRaWAN protocol. The LG01v2 uses a single-channel LoRa module to minimize the deployment cost for a private p2p LoRa wireless network.

Note: The LG01v2 can't register and connect to the LoRaWAN server(Such as The Things NetWork, AWS, or Chirpstack..)

LG01v2 uses Open Source Linux system. User can modify the Linux part and develop customize software base on it. It has 1.2Ghz Quad-Core CPU , 4GB eMMC storage and 512MB RAM for most application.

LG01v2 supports remote management. System Integrator can easy to remote monitor the gateway and maintain it.

                                                      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 Access and Configure LG01-v2

2.1.1 Find IP address of LG01-v2

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.

image-20220622100129-1.png

Method 2:  Connect via LG01v2 Fallback IP

image-20230107084650-2.png

Steps to connect via fallback IP:

1. Connect the PC's Ethernet port to LG01v2's WAN port

2. Configure PC's Ethernet port has IP: 172.31.255.253 and Netmask: 255.255.255.252

Settings --> Network & Internet --> Ethernet --> Change advanced sharing options --> Double-click"Ethernet" --> Internet Protocol Version 4 (TCP/IPv4)

As in the below photo:

4. Build in Server

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

image-20230506113737-9.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>

7.3 How does LG01v2 communicate with LoRaWAN node

This example describes how to use LG01v2 and LSN50 to set up a  network,

In this case, users need to set LSN50 to work in ABP mode and transmit in only one frequency.

Assume we have a LG01v2 working in the frequency 868100000 now, below is the steps.

Step1: Configure the LG01v2

AT+FRE=868.100,868.100                    ---> TX and RX frequency set: 868100000
AT+BW=0,0                                          ---> TX and RX Bandwidth set: 125kHz
AT+SF=12,12                                        ---> TX and RX Spreading Factor set: SF12
AT+SYNCWORD=1                              --->  Syncword(0: private,1: public), the corresponding Lora shield syncword is 0x12

Step2:  Run AT commands to make the LSN50 work in Single frequency and ABP mode.

For more information on how to use AT commands in LSN50v2, please refer to this link: LSN50v2-S31-S31B Use AT Command

Below are the AT commands:

AT+FDR                                                ---> Reset Parameters to Factory Default, Keys Reserve
AT+NJM=0                                           --->  Set to ABP mode
AT+ADR=0                                           --->  Set the Adaptive Data Rate Off
AT+DR=0                                             ---> Set Data Rate (Set AT+DR=3 for 915 band)
AT+TDC=300000                                 --->  Set transmit interval to 5 minutes
AT+CHS=868100000                           ---> Set transmit frequency to 868.1Mhz
AT+DADDR=FFFFF111                    ---> Set Device Address to 26 01 1A F1
ATZ                                                      ---> Reset MCU

Step3:  Check result

User can plot the temperature and humidity chat via LG01v2 built-in IoT server.

User can import this example in Node-Red: LG01v2_LSN50v2_S31.json

First the user needs to fill in the NwkSkey and AppSkey in the LoraWan Packet Decrypter node.

8. Trouble Shooting

8.1  Fallback IP does not work, how can users check

When the computer has completed the above fallback IP configuration,the LG01v2 Web UI is still not accessible via fallback IP.

1.Check whether the configuration is correct

Run the CMD command to ipconfig and ping 172.31.255.254.

If this fails, the user needs to reconfigure.
