First steps receiving data from a uPart using a  cPart bridge

If you follow the steps below you can easily receive data from a uPart and see the sent data in the Particle Analyser. Please note, that this guide is written for Windows (for device drivers and software for linux see!


1) Devices needed

uPart uPart
cpart cPart
USB bridge USB bridge


2) Downloading needed software and device drivers


3) Installing the software and device drivers

3.1) Install JDK 1.5

Install the Java Development Kit as described on the Sun page.

3.2) USB bridge software (Windows)

Start usbbridge_v100.msi from your computer and choose 'Typical '


If finished, you should find a link to the program on your desktop.

3.3) Windows Drivers for the USB bridge

Extract the into a directory of your choice.

Now insert the USBBridge in your USB port. Please note that the receiver (cPart) should be
connected on the USB board on top like in the image shown below.

USB Bridge Hardware

Windows will now request you to select the driver.
Specify the Driver directory you chose earlier. The installation concludes automatically the correct .inf file.
Check for the "TecO particle USBBridge [based on libusb]" in the Device Manager. It should read like the following:

If you have already installed an older version of the USBBridge driver, pleas update it:

3.4 Particle Analyser

Depending on the version you downloaded the installation is slightly diffenent.

3.4.1) Delphi implementation

Extract to a directory of your choice. You will find the executable in the following directory: 2004_01_14\ParticleAnalyzer\Analyzer.exe.

3.4.2) Java implementation

Extract to a directory of your choice. In that directory you will find a run.bat to execute it.

3.4.3) Java Webstart

Click on Webstart and follow the instructions on screen. You need to accept the certificate in order to use it. After the installation all the files are stored in a temporary folder for offline usage.


4.) Starting the applications

4.1) uPart

To start a uPart simply insert a 3 volt lithium manganese battery in the battery slot of the uPart.


4.2) USBBridge program

Start the USB bridge program via the link on your desktop:USBBridge start link on desktop

Switch it to "uPart" and press the "Start" button.
Start a uPart (if not done yet) by inserting a batterie and check for incomming data.


4.3 Particle Analyser

3.4.1) Delphi implementation

Execute Analyzer.exe in the program directory

particle analyser


Switch to the tab Settings and check if the ports are correctly entered as shown below. Note: The USB bridge software listens on port 5556 and sends any received RF packets to the local network on port 5555 where the particle analyser grabs them. So the listen and send port must be in reverse order.


Now press the Start button and switch to the console view where the incoming packets are shown.

analyser console


3.4.2) Java implementation && Java Webstart

Execute the run.bat in the install folder or the ParticleAnalyzer link which should be on the desktop (otherwise you have use the Webstart link). The first start might take some time because the Java virtual machine has to be loaded (as you may know from other applications).

Please check if the ports are set correctly and press Start.

Java PA

After a packet has been received it will be shown in the list and the ID of the sender uPart is on the right side. If you click on the ID you can filter and show only the selected uPart. In this example I activated 2 uParts.


Note: Every USB bridge is broadcasting any data received via RF to the local network. If you have 2 bridges running you might receive duplicates!

4) Congratulations! It should work now!
