1Introduction
1.1 What is the LPS8
The LPS8 is an open source LoRaWAN Gateway. It lets you bridge LoRa wireless network to an IP network via
WiFi, Ethernet. The LoRa wireless allows users to send data and reach extremely long ranges at low data-rates.
The LPS8 uses Semtech packet forwarder and fully compatible with LoRaWAN protocol. It includes a SX1308
LoRa concentrator, which provides 10 programmable parallel demodulation paths.
LPS8 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.

1.5 LPS8 Applications
1.6 LED Indicators
LPS8 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.

2Access and Configure LPS8
The LPS8 is configured as a WiFi Access Point by factory default. You can access and configure the
LPS8 after connecting to its WiFi network, or via its WAN Ethernet port.
2.1 Find IP address of LPS8
2.1.1 Connect via WiFi
At the first boot of LPS8, 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 LPS8 has the default IP
10.130.1.1
2.1.2 Connect via Ethernet with DHCP IP from router

www.dragino.com
LPS8 LoRaWAN Gateway User Manual 9 / 32
Alternatively, connect the LPS8 Ethernet port to your router and LPS8 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 LPS8. You can also use this IP to connect.
2.1.3 Connect via WiFi with DHCP IP from router
If the LPS8 already connect to the router via WiFi, use can use the WiFi IP to connect to LPS8.
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.

2.2 Access Configure Web UI
Web Interface
Open a browser on the PC and type in the LPS8 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 LPS8 as shown below.
