The LG308 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 LG308 uses Semtech packet forwarder and fully compatible with LoRaWAN protocol. It
includes a SX1301 LoRa concentrator, which provides 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 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 LG308
The LG308 is configured as a WiFi Access Point by default. User can access and configure the
LG308 after connecting to its WiFi network, or via its Ethernet port.
2.1 Find IP address of DLOS8
2.1.1 Connect via WiFi
At the first boot of LG308, it will auto generate an unsecure
WiFi network call dragino-xxxxxx
Note: In latest version firmware, it has been password
protected and the password is:
dragino+dragino
User can use the laptop to connect to this WiFi network. The
laptop will get an IP address 10.130.1.xxx and the LG308 has
the default IP 10.130.1.1
2.1.2 Connect via WAN port with DHCP IP from router
Alternatively, connect the LG308 WAN port to your router and LG308 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 LG308. You can also use this IP to connect.

2.1.3 Connect via LAN port with direct connection from PC
The LG308 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 via WiFi with DHCP IP from router
If the LG308 already connect to the router via WiFi, use can use the WiFi IP to connect to LG308.
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 LG308 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 (If the IP is assigned by uplink
router)
You will see the login interface of LG308 as shown below.

3. Typical Network Setup
3.1 Overview
LG308 supports flexible network set up for different environment. This section describes the
typical network topology can be set in LG308. The typical 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, 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, LG308 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:

4. Example : Configure as a LoRaWAN gateway
LG308 is fully compatible with LoRaWAN protocol. It use the legacy Semtech Packet forwarder to
forward the LoRaWAN packets to server, the structure is as below.
This chapter describes how to use LG308 to work with TTN LoRaWAN Server. The method to
work with other LoRaWAN server is 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 gateway id is: a840411b8268ffff

Notice: The TTN router should match the Frequency Plan you choose, otherwise you will have
problem for End Node to join the network. If you don’t which router you need to select, please
10.3 I configured LG308 for WiFi access and lost its IP. What to do now?
The LG308 has a fall-back ip in its LAN port. This IP is always enabled so user can use fall back ip
to access LG308 no matter what the WiFi IP is. The fall back ip is useful for connect and debug the
unit.
(Note:fallback ip can be disabled in the LAN and DHCP page)
Steps to connect via fall back IP:
1. Connect PC’s Ethernet port to LG01’s LAN port
2. Configure PC’s Ethernet port has IP: 172.31.255.253 and netmask: 255.255.255.252
As below photo:
3. In PC, use 172.31.255.254 to access LG308 via Web or Console.
