1 Introduction
1.1 What is the LPS8N
The LPS8N is an open source LoRaWAN Indoor 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 LPS8N uses Semtech packet forwarder & LoRaWAN Basic Station and fully compatible with
LoRaWAN protocol. It includes a SX1302 LoRa concentrator, which provides 10 programmable
parallel demodulation paths.
LPS8N 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.
LPS8N 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.

1.5 LPS8N Applications
1.6 LED Indicators
LPS8N has totally four LEDs, They are:
➢Power LED : This RED LED will be solid on if the device is properly powered.
➢LoRa LED : This RGB LED will blink GREEN when LoRaWAN module starts or transmit a
packet.
➢SYS LED :This RGB LED will shows different colors on different state:
✓SOLID BLUE: Device is alive with LoRaWAN server connection.
✓BLINKING BLUE: a) Device has internet connection but no LoRaWAN Connection. or b)
Device is in booting stage, in this stage, it will BLINKING BLUE for several seconds and
then with SOLID RED and BLINKING BLUE together
✓SOLID RED: Device doesn’t have Internet connection.
➢ETH LED : This LED shows the ETH interface connection status.

2 Access and Configure LPS8N
The LPS8N is configured as a WiFi Access Point by factory default. You can access and configure
the LPS8N after connecting to its WiFi network, or via its WAN Ethernet port.
2.1 Find IP address of LPS8N
2.1.1 Connect via WiFi
At the first boot of LPS8N, it will auto generate a WiFi network
called dragino-xxxxxx with password:
dragino+dragino
You can use a PC to connect to this WiFi network. The PC will
get an IP address 10.130.1.xxx and the LPS8N has the default IP
10.130.1.1
2.1.2 Connect via Ethernet with DHCP IP from router
Alternatively, connect the LPS8N Ethernet port to your router and LPS8N 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 LPS8N. You can also use this IP to connect.

LPS8 LoRaWAN Gateway User Manual 11 / 55
2.1.3 Connect via WiFi with DHCP IP from router
If the LPS8N already connect to the router via WiFi, use can use the WiFi IP to connect to LPS8N.
2.1.4 Connect via Ethernet with fall back ip
The WAN port also has a fall back ip address for access if user doesn’t connect to uplink router.
Click here to see how to configure.

2.2 Access Configure Web UI
Web Interface
Open a browser on the PC and type in the LPS8N 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 (The web port has been changed to
8000 in WAN interface(WAN port or WiFi Client Mode) since firmware 5.3.xxx firmware)
You will see the login interface of LPS8N as shown below.
The account details for Web Login are:
User Name: root

3 Typical Network Setup
3.1 Overview
The LPS8N supports flexible network set up for different environments. This section describes the
typical network topology can be set in LPS8N. The network set up includes:
✓WAN Port Internet Mode
✓WiFi Client Mode
✓WiFi AP Mode
3.2 Use WAN port to access Internet
By default, the LPS8N is set to use the WAN port to connect to an upstream network. When you
connect the LPS8N’s WAN port to an upstream router, LPS8N 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, LPS8N 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 LPS8N 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 LPS8N 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.
4Example: Configure as a LoRaWAN gateway
LPS8N 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.

4.1 Create a gateway in TTN V3 Server
Step 1: Get a Unique gateway ID.
Every LPS8N 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
