USB RFID reader with cp2102&VCP

Hello,

 

Has anyone used to work with RFID reader as in the link, http://www.jwm-rfid.com/product_view.php?id=52.

 

I want to communicate with the device over the VCP by using C# with .net serial port library. However, I still cannot retrieve any data yet.

 

Any suggestion would be appreciated.

You can get all of the documentation about cp2102 from the webpage as below.

Thank you. I have read them all and already started on coding. However, I am struggling with reading the data from the device. I don't know the exact instruction set to send over to get back the data.

 

However, there is a program from the manufactory, is it possible to do the port sniffing in VCP?

hi @paolovelove

 

For my understanding, the exact instruction should be provided by the RFID reader vendor, and you can try to send the requested instruction set with a serial tool through the CP2102 virtual COM port firstly, and check if can get any reply from the RFID reader.
