Connections problems between USRP1 hardwares

Dear all,

I’m a beginner in GNU Radio; I just want to discover the software and
try to realize some applications with my USRP1 hardwares.

My USRP 1 are composed by daughter boards XCVR2450 2.4GHz and 5GHz

I’m trying to transmit a file between two computers with the USRP1 but
it is not working. I’m using GSMK modulation.

You can find attached the pictures of my transmitter and receiver.

I don’t receive anything. Am I forgetting something?

Is there a specific procedure to test the USRP1 hardware?

I’m using the programs and to know if my
USRP are well connected. But I don’t know what is the meaning of the
true and false answers. Can someone help me?

In the project that I want to implement (spectrum sensing), I want to
focus on implementing specific algorithms rather than python coding due
limited time and the fact that I am not familiar with python coding. Do
you think it is better use USRP2 and matlab, if anyone have tried it,
please let me know about your experience?

Thanks for your answers.

Best regards,
