Gateway has a range of over 15Km line-of-sight and over 2Km in dense urban
environments.
The DIY Gateway brings more flexiblity for the developer to create an enterprise grade
solution: our most important difference is our flexible development support structure,
allowing for faster development and time to market. We offer both a ready to go
firmware image for openWRT based platforms and an open SDK for integration into
hardware to support the needs of each customer.

6WEB Configuration Guide
6.1 Connect the Gateway
1. Via WiFi
The WiFi of the gateway works in AP mode by default. The default SSID format is
"RAKxxxx_xxxx” such as "RAK7240_D3BD", “D3BD” is the last two bytes of the
gateway MAC address. Connecting to the SSID using your PC, then can automatically
get the IP address. After successful connection, the WEB management platform can be
accessed through the IP address 192.168.230.1 of the gateway LAN interface.
2. Via IP Alias of WAN Port
The WAN interface of the gateway has a static IP (Auto IP Alias) generated
automatically according to the MAC address. The format of the IP address is
169.254.x.x/255.255.0.0. The 3 and 4 bytes of IP correspond to the decimal
representation of the fifth and sixth bytes of the MAC address, respectively. For
example, the MAC address is xx: xx: xx: xx: D3: BD, and the Alias IP is
169.254.211.189/255.255.0.0.
Connecting your PC's Ethernet interface to gateway WAN interface, and adding
169.254.x.x/255.255.0.0 IP address to PC's Ethernet interface, then we can access
gateway's WEB management platform through Alias IP.
3. Via WAN Port DHCP IP
When DHCP Server is in the network where the gateway WAN interface is located, the
WAN interface can automatically get the IP address. After inquiring the IP address of
the gateway through DHCP Server, the WEB management platform of the gateway can
be accessed through the DHCP IP address of WAN interface.
6.2 WEB Management Platform
Open the browser, enter the IP address of the gateway, and open the login page of the
WEB Management Platform. Enter the user name and password (user name and
password default is root) and click login.

Recevied: Shows the total number of LoRa messages received by the LoRa gateway;
Transmittd: Shows the LoRa message sent by the LoRa gateway;
Active Nodes: Shows the number of active LoRa nodes within the LoRa gateway coverage
(nodes that sent messages in 10 minutes)
Busy Nodes: Shows the number of busy nodes within the LoRa gateway coverage (nodes
with an average message spacing of less than 60s)
Dutycycle Of LoRa Channel:
The chart shows the thermodynamic charts of the "duty cycle" of all channels over time over
a period of 12 hours. The longitudinal axis is time and the minimum interval is 60s. The
horizontal axis is the channel frequency. Each value represents the average duty cycle of
the channel within 60s (range is: 0%-100%), green represents the low duty cycle, and red
represents the high duty cycle.
LoRa Traffic:
The chart shows the LoRa packet rate（packet/min）of each spread factor in two hours.
The vertical axis represents the LoRa packet rate, in packet/min, six colors represent six
spread factors, and the total height represents the sum of all the rates of LoRa packet.

6.2.6 Network Ping Watchdog
Figure 13 | Ping Watchdog Interface
Ping Watchdog monitors the communication quality of network links by constantly pinging
the specified IP address or domain name on the specified uplink network interface. When
network link failures are found, scheduled measures are taken automatically, such as
<restart interface>/<reduce the priority of this uplink network interface>/<restart the device>.

20
RAK7249
20
RAK7249 User Manual V1.3
Note: Reducing the priority of an uplink interface only works when the LoRa gateway uses
both the Ethernet uplink link and the LTE cellular network uplink link.
WAN interface represents the Ethernet uplink interface and WWAN represents the LTE
cellular network uplink interface. If Ping watchdog is opened on both uplink network
interfaces at the same time and action is set to Increase Gatway Metric, the two uplink links
form backup links and automatically switch to another link when one link fails. The priority of
the two links is determined by the default gatway metric of their respective network
interfaces. The default gatway metric can be set in Network->WAN Network and Network-
>Cellular Network. The lower the gatway metric, the higher the priority of the link.
Figure 14 | Ping Watchdog Configuration
6.2.7 Backup or Upgrade
In Backup/Flash Firmware page, you can backup your configuration or restore your gateway,
and you can upgrade to a new firmware. As shown in the following figure.
