1. Introduction
1.1 What is the LG308N

The LG308N is an open sourceLoRaWAN Pico Gateway. It lets you bridge LoRa wireless network to an IP
network via WiFi, Ethernet, 3G or 4G cellular network. The LoRa wireless allows users to send data and reach
extremely long ranges at low data-rates.
The LG308N uses Semtech packet forwarderand fully compatible with LoRaWAN protocol. It includes a SX1302
LoRa concentrator, which provides 10 programmable parallel demodulation paths.
LG308N has pre-configured standard LoRaWAN frequency bands to use for different countries. User can also
customized the frequency bands to use in their own LoRa network.
LG308N can communicate with ABP LoRaWAN end node without LoRaWAN server. System integrator can use it to
integrate with their existing IoT Service without set up own LoRaWAN server or use 3rd party LoRaWAN service.

2. Access and Configure LG308N
The LG308N is configured as a WiFi Access Point by default. User can access and configure the LG308N after
connecting to its WiFi network, or via its Ethernet port.
2.1 Find IP address of LG308N
2.1.1 Connect via WiFi
At the first boot of LG308N, it will auto generate a WiFi network called dragino-xxxxxxwith password:
Note: In latest version firmware, it has been password protected and the password is:dragino
+dragino

User can use a PC to connect to this WiFi network. The PC will get an IP address 10.130.1.xxx and the LG308N has
the default IP 10.130.1.1

2.1.2 Connect via WAN port with DHCP IP from router
Alternatively, connect the LG308N WAN port to your router and LG308N will 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
LG308N. You can also use this IP to connect.

2.1.3 Connect via LAN port with direct connection from PC
The LG308N LAN port is configured as DHCP router by default, user can connect the PC to LAN port and set
PC to DHCP mode, it will get IP from LAN port and be able to access to the device. The default IP in LAN port is
10.130.1.1
2.1.4 Connect WiFi with DHCP IP from router

If the LG308N already connect to the router via WiFi, use can use the WiFi IP to connect to LG308N.
2.1.5 Connect via LAN port by fall back ip
The LAN port also has a fall back ip address for access if user doesn't connect to uplink router.
2.2 Access Configure Web UI
Web Interface
Open a browser on the PC and type the LG308N ip address (depends on your connect method)
http://10.130.1.1/ (Access via WiFi AP network)
or
http://IP_ADDRESS or http:// IP_ADDRESS:8000
You will see the login interface of DLOS8N as shown below.
The account details for Web Login are:
User Name: root
Password: dragino
3. Typical Network Setup
3.1 Overview

LG308N supports flexible network set up for different environment. This section describes the typical network
topology can be set in LG308N. The typical network set up includes:
•WAN Port Internet Mode
•WiFi Client Mode
•WiFi AP Mode
•Cellular Mode
3.2 Use WAN port to access Internet
By default, the LG308N is set to use the WAN port to connect to an upstream network. When you connect the
LG308N's WAN port to an upstream router, LG308N will get an IP address from the router and have Internet access
via the upstream router. The network status can be checked in the home page:
3.3 Access the Internet as a WiFi Client
In the WiFi Client Mode, LG308N acts as a WiFi client and gets DHCP from an upstream router via WiFi.
The settings for WiFi Client is under page System--> WiFi --> WiFi WAN Client Settings

In the WiFi Survey Choose the WiFi AP, and input the Passphrase then clickSave & Applyto connect.

3.4 Use built-in 4G modem for internet access
If the LG308N has 3G/4G Cellular modem, user can use it as main internet connection or back up.
First, install the Micro SIM card as below direction
Second, Power off/ ON LG308N to let it detect the SIM card.
The set up page is System --> Cellular

While use the cellular as Backup WAN, device will use Cellular for internet connection while WAN port or WiFi is not
valid and switch back to WAN port or WiFi after they recover.

3.5 Check Internet connection
In the home page, we can check the Internet connection.
•GREEN Tick : This interface has Internet connection.
•Yellow Tick : This interface has IP address but don't use it for internet connection.
•RED Cross : This interface doesn't connected.
4. Example: Configure as a LoRaWAN gateway

LG308N is fully compatible with LoRaWAN protocol. It uses the legacy Semtech Packet forwarder to forward the
LoRaWAN packets to server. The structure is as below.

This chapter describes how to use the LG308N to work with(TTN v3)LoRaWAN Server
(www.thethingsnetwork.org)
4.1 Create a gateway in TTN V3 Server
Step 1: Get a Unique gateway ID.

Every LG308N has a unique gateway id. The ID can be found at LoRaWAN page:



The example gateway id is: a840411e96744154
Step 2: Sign up a user account in TTN server
https://account.thethingsnetwork.org/register
Step 3: Choose the TTNv3 Cluster Picker


Note: Choose the cluster corresponds to a specific Gateway server address
• Europe 1 corresponding Gateway server address:eu1.cloud.thethings.network
• North America 1 corresponding Gateway server address:nam1.cloud.thethings.network
• Australia 1 corresponding Gateway server address:au1.cloud.thethings.network
• Legacy V2 Console : TTN v2 shuts down in December 2021
Step 4: Create a Gateway

Click the Gateway icon and then click Add gateway.
Open the following page:


Notice:Gateway Server address must match the gateway configuration, otherwise you will have
problem for End Node to join the network.

After creating the gateway, you can see the gateway info, as below.

4.2 Configure LG308N to connect to TTN v3
You can now configure the LG308N to let it connect to TTN network V3.
Make sure your LG308N has a working Internet Connection first.
Choose the right server provider and click Save&Apply.

Note:The server address must match the Gateway server address you choose in TTN V3.
In the home page, we can see the LoRaWAN connection is ready now.
In TTN v3 portal, we can also see the gateway is connected.
