2.2.3 Connecting to the Board via WiFi
If you want to connect to the sensor via USB instead of WiFi, please skip this section and go back
to Section 2.2.2.
Please be aware that the WiFi module has a limited transfer rate. The
maximum possible frame update rate is about 10 Hz when using the WiFi connection.
Once
you power-up the sensor module in WiFi configuration, the WiFi module’s LED is flashing in blue.
The WiFi module opens an own access point. This may last approximately 40 seconds. Please set
the WiFi module of your PC to use automatic IP address selection via DHCP to get an IP address
from the sensor. If your PC’s WiFi module uses a static IP, it might not be possible to connect to the
WiFi module of the sensor. Connect to the sensor’s WiFi access point using the following login
credentials:
SSID:
SimpleRadar-<uuid>
Password:
SimpleRadar
Once the sensor’s WiFi module has opened an access point, it waits for approximately 40 seconds
until it starts the sensor operation and the blue LED is switched off. On Windows, the IP address
that was assigned by the sensor’s WiFi module to your PC can be checked in the network
manager. Proceed to Section 2.2.4 for running the graphical user interface.
2.2.4 Starting the Graphical User Interface (Silicon Radar WebGUI)
You can find the Silicon Radar WebGUI in the Install Package in the ‘Software’ folder. It is portable
and can be copied to a path of your choice on your PC. The user interface is started by opening the
‘startSimple.html’ file or the ‘index.html’ file in a Chrome or Firefox Webbrowser. Once the WebGUI
is launched, the main window is displayed, also see Figure 8 (left).
WiFi only:
If you are using a WiFi connection to connect to the sensor board, unfold the ‘COM’
section in the control panel on the left side of the WebGUI. Provide the IP address and the port of
the WiFi module of the sensor you want to connect to before you proceed, like so:
‘192.168.4.1:9090’. The standard port is 9090.
Click the ‘Connect’ button on the top left to connect to the WebSocket provided by the
COM2WebSocket tool or to the WiFi module of the sensor board. The WebGUI should display the
sensor data as shown in Figure 8 (right).

The WebGUI can now be used as described in Section 3.
