Re: [Discuss-gnuradio] UHD source (data keeps being sent)

2011-12-28 Thread UB
I have two USRP1 (each connected to a laptop), separated 30cm apart. Each have a single Antenna connected to RFX2400 daughter card. I am running Ubuntu LTS version. I downloaded GnuRadio+UHD from your (Marcus Leech) script 2 months ago. Below are the details of my GnuRadio version:

No I don't see the tone/spike. Infact, even with my own code, if I just tx and connect the source USRP to uhd_fft.py file, I dont find any peak at the frequency range. Surely, this clears that the sink USRP could not be transmitting, but then why do I get similar repeated samples in my source

Matt, It looks like the problem here lies within boost itself. Until boost 1.47 a deadlock condition existed durring concurrent condition_wait() and interrupt() calls, which is what we are running into. this seems to happen most commonly as a TPB thread body is blocking on an input condition
