Hello Everybody,

I am currently trying to write a program able to manage a communication from a reader point of vue to communicate with a unique tag using laboratory instruments : modulator, HF signal generator, spectrum analyser and oscilloscope.
Obviously, the process follows EPC requirements, but I am facing a little difficulty : after the Select commands, the reader has to know the 16-bit random number generated by the tag as an identifier and to backscatter it.

Does someone know if a 'debug' mode allows us to know the value in advance, or to send the value we want to the tag ? It would be helpful .

Thanks in advance.
