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.
