Making a loop-back test
To verify that the UCBT232B/EXA is properly working, paired and connected you
can make a loop-back test. In this test you will check if you can send data from your
computer out through your computer’s Bluetooth (which actually is a virtual serial
COM port) to the TX (transmit) wire on the UCBT232B/EXA (pin 2), loop it back
(by the help of a paper clip) and then receive it back on the RX (receive) wire of the
UCBT232B/EXA, and finally receive it back on your computer.
To make the loop-back test you will need to setup and pair the UCBT232B/EXA with
either your computer’s build-in Bluetooth or a USB Bluetooth dongle as shown in the
image below:
Please carefully follow the steps starting on page 2 of this guide to setup and link the
UCBT232B/EXA with your computer. In order to successfully perform the loop-back
test the UCBT232B/EXA MUST be properly linked with your computer.

Click Tools > Configuration and enter the parameters of the UCBT232B/EXA at
the COM port which it has created, in this case COM 10.
To check which COM port number you need to enter in AccessPort see page 7 in
this guide. It is important you enter the correct COM port number otherwise you
will not be able to communicate with the UCBT232B/EXA.
