EasyRadar Sensor Evaluation Kit 
 

- 8 - 

2.4  Software Installation 

The evaluation software is displayed in a Web Browser which supports WebGL.  
We recommend the following Browsers: 
Chrome, Firefox. 

2.4.1 Connecting to the board using a wireless LAN connection 

Due to the wireless LAN connectivity of the module, the installation process is very straightforward. 
On  power-up  the  module  searches  for  the  last  saved  WiFi  access  point.  This  is  indicated  by  the 
rapidly flashing blue LED. If there is no known WiFi access point (AP) accessible, the WiFi module 
opens an own AP. This is indicated by the slowly flashing blue LED on the module (40 secs).  
Please connect to this AP using the following login credentials: 
SSID: 

EasyRadar

Greetings

 

The module is now in AP mode and waits for 40 seconds until it starts the Radar application.  
If the connection is successful, the blue LED is switched off. 
Please find out the IP of the module by checking your DHCP server (WLAN AP). 
The module can now be used as described in chapter 3. 

2.4.2 Connecting the board via USB 

Connecting the board via USB is only supported for Windows systems at this time. 
To connect the board via USB, the ST Microelectronics Virtual Com Port driver has to be installed 
first. Please download it from the ST Webpage: 

http://www2.st.com/content/st_com/en/products/development-tools/software-development-
tools/stm32-software-development-tools/stm32-utilities/stsw-stm32102.html

 

or from the Silicon Radar download page: 
[link] 
 
The second step is to install a 32-bit Java Runtime Environment from: 

http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

 

Please make sure you select a 32-Bit driver or the communication will not work. 
 
Thirdly,  run  the  Com2WebSocket  application  after  changing  the  path  in  the  runme.bat  to  your 
java.exe path. 
A small window with the available com ports will open:

Please select the appropriate COM port of your Evalkit, and select 230400 baud as the baudrate. 
Then click open. The program then opens a Websocket Server which is fed with the data from the 
com port. 
The Evalkit is now ready to run.
