1 Introduction
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.

2 Access 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
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.
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 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.
The account details for Web Login are:
User Name: root
Password: dragino

3 Typical Network Setup
3.1 Overview
The LPS8 supports flexible network set up for different environments. This section describes the
typical network topology can be set in LPS8. 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 LPS8 is set to use the WAN port to connect to an upstream network. When you
connect the LPS8’s WAN port to an upstream router, LPS8 will get an IP address from the router
and have Internet access via the upstream router. The network status can be checked as below:

LPS8 LoRaWAN Gateway User Manual 13 / 50
3.3 Access the Internet as a WiFi Client.
In the WiFi Client Mode, LPS8 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 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
LPS8 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.
This chapter describes how to use the LPS8 to work with
TheThingsNetwork v3(TTN v3) LoRaWAN Server (www.thethingsnetwork.org)

LPS8 LoRaWAN Gateway User Manual 15 / 50
4.1 Create a gateway in TTN V3 Server
Step 1: Get a Unique gateway ID.
Every LPS8 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
Step 4: Create a Gateway
Click the Gateway icon and then click Add gateway.
Open the following page:

LPS8 LoRaWAN Gateway User Manual 17 / 50
Notice: Gateway Server address must match the gateway configuration, otherwise you will have
problem for End Node to join the network.
After creating the gateway, you can see the gateway info, as below.

4.2 Configure LPS8 to connect to TTN v3
You can now configure the LPS8 to let it connect to TTN network V3.
Make sure your LPS8 has a working Internet Connection first.
Choose the right server provider and click Save&Apply
Note: The server address must match the Gateway server address you choose in TTN V3.
In the home page, we can see the LoRaWAN connection is ready now.

4.3 Configure frequency
We also need to set the frequency plan in LPS8 to match the end node we use, so to receive the
LoRaWAN packets from the LoRaWAN sensor.
In logread page, user can check the frequency actually used.
