1 Introduction
1.1 What is the LG308
The LG308 is an open source LoRaWAN Gateway. It lets you bridge LoRa wireless network to an IP
network via WiFi, Ethernet, 3G or 4G cellular. The LoRa wireless allows users to send data and reach
extremely long ranges at low data-rates.

The LG308 is use semtech packet forwarder and fully compatible with LoRaWAN protocol. It
includes a SX1301 LoRa concentrator, which provide 10 programmable parallel demodulation paths.
LG308 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.
LG308 has optional built-in 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 LG308
2.1 Access and Configure the LG308 via WiFi or Ethernet
The LG308 is configured as a WiFi Access Point by factory default. You can access and configure
the LG308 after connecting to its WiFi network, or via its LAN Ethernet port.
WiFi
At the first boot of LG308, it will auto generate an open WiFi
network called dragino-xxxxxx
You can use a PC to connect to this WiFi network. The PC will
get an IP address 10.130.1.xxx and the LG308 has the default
IP 10.130.1.1
Ethernet
Alternatively, you can connect your PC to the LG308 LAN port
via Ethernet cable and obtain an IP address via DHCP.
Web Interface
Open a browser on the PC and type in the address:
http://10.130.1.1/
You will see the login interface of LG308 as shown below.
The account details for Web Login are:

3 Typical Network Setup
3.1 Overview
The LG308 supports flexible network set up for different environments. This section describes
the typical network topology can be set in LG308. The network set up includes:
●WAN Port Internet Mode
●WiFi Client Mode
●WiFi AP Mode
●USB Dial Up Mode
3.2 Use WAN port to access Internet
By default, the LG308 is set to use the WAN port to connect to an upstream network. When you
connect the LG308’s WAN port to an upstream router, the LG308 will get an IP address from the
router and have Internet access via the upstream router. The network status can be checked as
below:

3.3 Access the Internet as a WiFi Client.
In the WiFi Client Mode, the LG308 acts as a WiFi client and gets DHCP from an upstream router
via WiFi.
The steps to set up as a WiFi Client are as below:
Step1:
In Network -> Wireless, select Radio0 interface and scan.
Step2:
Select the Wireless AP and join:
Step3:
In the Network->Wireless page, disable WiFi AP network.

4 Example : Configure as a LoRaWAN gateway
LG308 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 LG308 to work with
TheThingsNetwork (TTN) LoRaWAN Server (www.thethingsnetwork.org)
The method to work with other LoRaWAN servers will be similar.

4.1 Create a gateway in TTN Server
Step 1: Get a Unique gateway ID.
Every LG308 has a unique gateway id. The ID can be found at LoRaWAN page:
The example gateway id is: a840411b8268ffff
Step 2: Sign up a user account in TTN server

4.4 Add a LoRaWAN End Device
This section shows how to add a LoRaWAN End device to a LoRaWAN network and see the data
from TTN web site.
We use LT-33222-L IO Controller as a reference device - the setup for other LoRaWAN devices
will be similar.
Step 1: Create a Device definition in TTN with the OTAA keys from the example LT-33222-L IO
Controller device.
Three codes are required to define the device in TTN:
DEV EUI - Unique ID code for a particular device.
APP EUI - ID code for an Application defined in TTN.
APP Key - Unique key to secure communications with a particular device.
A set of these codes are stored in each device by the manufacturer as the default codes for that
particular device. Each device is shipped with a sticker with the default Device EUI as shown
below.
Note: You may be able to change these codes in a device by using a configuration facility on the
device e.g. the LT33222 uses a serial port access and a series of AT commands. Changing the
codes may be necessary in the case where you have to use codes assigned by a LoRa WAN
server.
For the TTN server, you can use the codes set in the device as in the following example.
Select Add Application to open the screen below.
Note that there is an APP EUI already created by TTN, but this is not the one set in the device. To
add the APP EUI for the LT33222 device, select Manage EUIs and Add EUI, then enter the
required code.
