Capture traffic between 2 UDP End points

[rdonnay]

I have a customer who wants me to write an Xbase++ program that communicates with a temperature scanner board.
The software that comes with it is terrible.
It's made in China.

There is no spec for the communication with the board, but there is very little traffic.
When a person puts their forehead near the sensor, it measures the temperature and sends that info to the software.
Unfortunately, there is no mechanism to store the information to a database, so I need to write a program for this.

I'm looking for software that will capture the traffic to see how this thing communicates.
I tried Fiddler. It has filtering capability but it doesn't seem to do anything.

Has anyone hacked communication between 2 UDP end points?

Hi,
I encountered a similar problem but with RS232 communication and I solved it.
I put a pc between the machine and the pc communicating with (my pc communicates with the machine on one side and with the pc on the other).
I read the data on one side and send it back to the other and vice versa.
I store the data read to process them.
I believe it will be the same and may solve your problem.
It's your turn.
