[Discuss-gnuradio] My USRP sometime can receive data, sometime not!

[Lebowski80]

Hello everyone,

I've got four USRPs and they are equal and the boards integrated are
XCVR2450 Transceivers. I want to transmit data from one USRP to another one
using the code found in benchmark_tx.py and benchmark_rx.py; I'm doing the
experiments using two USRPs at a time. Three of them work well; I mean that
they can transmit and receive correctly what I send. Changing their roles
(sometimes I use one USRP to transmit and sometimes to receive), they keep
working well. Only one of them sometimes can receive the packets while
sometimes it cannot receive anithing, I was doing always the same experiment
with the same code and the same hypothesis (i.e. fequency, bit rate...), I
suppose that such a USRP has got some factory defect but I'm not sure! Can
anyone tell me wich is the problem? As the hardwares and the software that
I'm using are the same how it is possible to get different results?

Thanks in advance!
