1. Introduction
1.1 What is LG01N & OLG01
LG01N & OLG01N are an open source single channel LoRa 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. It provides ultra-long range
spread spectrum communication and high interference immunity.
LG01N & OLG01N have rich internet connection method such as WiFi interface, Ethernet port
and 3G/4G Cellular. These Interfaces provide flexible methods for users to connect their sensor
networks to Internet.
LG01N & OLG01N can support the LoRaWAN protocol in single frequency and customized LoRa
transition protocol.
LG01N can be used to provide a low cost IoT wireless solution to support 50~100 sensor nodes.
Except limited LoRaWAN mode, LG01N can support multiply working mode such as: MQTT mode,
TCP/IP Client mode to fit different requirement for IoT connection.
LG01N & OLG01N provide a low cost for your IoT network connection. Compare to the cost with
normal SX1301 LoRaWAN solution. LG01N & OLG01N is only of its 1/4 or less cost. This makes the
LG01N very suitable to set up small scale LoRa network or use it to extend the coverage of
current LoRaWAN network.

2. Access LG01N
Access and configure LG01
The LG01N is configured as a WiFi AP by factory default. User can access and configure the LG01N
after connect to its WiFi network.
At the first boot of LG01N, it will auto generate an unsecure
WiFi network call dragino-xxxxxx
User can use the laptop to connect to this WiFi network. The
laptop will get an IP address 10.130.1.xxx and the LG01 has the
default IP 10.130.1.1
Open a browser in the laptop and type
http://10.130.1.1/cgi-bin/luci/admin
User will see the login interface of LG01N.
The account for Web Login is:
User Name: root
Password: dragino
Notice: In case the WiFi network is disabled, user can connect the PC to LG01N’s LAN
port, the PC will get DHCP from LG01N, and be able to access it.

3. Typical Network Setup
3.1 Overview
LG01N supports flexible network set up for different environment. This section describes the
typical network topology can be set in LG01N. 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, the LG01N set to use WAN port as network connection. When connect LG01N’s WAN
port to router, LG01N will get IP from router and have internet access. The network status is as
below:

LoRa Gateway User Manual ---Update:2018-12-28 13 / 59
3.3 Access Internet as a WiFi Client.
In the WiFi Client Mode, Dragino acts as a WiFi client and gets IP from uplink router via WiFi.
The step to set is as below:
Step1:
In network -> Wireless, select Radio0 interface and scan.
Step2:
Select the wireless AP and join:
Step3:
In network->wireless page, disable WiFi AP network. Notice: After doing that, you will lose
connection if your computer connects to the LG01N via LG01N’s wifi network.

4. Example 1: Configure as a LoRaWAN gateway –Limited LoRaWAN mode
LG02 has two LoRa channels and can be configured as a Dual Channel LoRaWAN gateway. LG02 is
pre-configured to support one uplink channel and one downlink channel in the LoRaWAN mode.
This mode works as below diagram:
This chapter describes how to use LG01N 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 LG01N has a unique gateway id. The id can be found at LoRaWAN page:

www.dragino.com
LoRa Gateway User Manual ---Update:2018-12-28 19 / 59
The gateway id is: a840411b6fc44150
Step 2: Sign up an user account in TTN server
Step 3: Create a Gateway in TTN

www.dragino.com
LoRa Gateway User Manual ---Update:2018-12-28 20 / 59
After create the gateway, we can see the gateway info, as below, the Status shows “not
connected”because the LG01N doesn’t configure to send update status yet.
4.2 Configure LG01N Gateway
4.2.1 Configure to connect to LoRaWAN server
We should configure the LG01N now to let it connect to TTN network. Make sure your LG01N has
Internet Connection first.
Step1: Configure LG01N to act as raw forwarder mode
