Hello All,
I am trying to use popen to open an application under a block.
This looks something like that:
fp = popen(command, w); //doing it in write mode
if(!fp){

pclose(fp);
Now the thing is even if I am trying to track using (fp != NULL) it
still keep executing

Hi,
I just watched a video on this link:
http://www.youtube.com/watch?v=GCcKgrzbix4#at=42
They say they have ported OpenBTS and GR to RasPi and they could make phone
calls between 2 mobile phones.
Is that even possible?
Is RasPi strong enough for handling that kind of data?
I am very curious
HI Andrew,
Thanks, I will ask the question on OpenBTS, I thought that OpenBTS was a
layer on top of the GR, thanks for correcting me.

By default pybombs runs make with the -j4 option, allowing it to compile
things in parallel. This typically helps the compile go quicker. I
certainly wouldnt expect the gnuradio compile to have issues like this, but
you could edit the gnuradio recipe to force it not to use the -j4 option

Hi,
I have been using GRC and N210 to test my data acquisition scheme. My
previous scheme worked well with probably standard sampling rate (10Msps)
and LO at DC.
When I switched to a non-standard sampling rate (1.2 Msps) and non-standard
LO (1.105 MHz), all hell seems to break loose.
