Hi Ali,
Your CDA-2990 (OctoClock?) distributes both a frequency reference signal
(10MHz) and a time reference signal (1PPS). To get both USRP to record
at the same time, you need to first get them to run on the same time
internally, and then tell them both, in advance, at what time to start

I'd still believe the error is in the way you interact with the fifo.
Have you looked at setvbuf() or fflush()?
(e.g. "setvbuf(f, (char *)NULL, _IONBF, 0);" )

Hello everyone,
We have been using the USRP N210 with the WBX 50-2200 (40 MHz)

Our objective is to get as clea

Hi Thabet,
you can call these functions from anywhere.
In GNU Radio's current state, I'd however recommend you don't, for the
same reasons I discussed two weeks ago:

Hello,
I'm interested in reconfiguring the flowgraph of my app at runtime.
I see that there is a set of functions to do that: start/stop, lock/unlock,
connect/disconnect

I have 2 questions about this:
1- Is it possible to use these funct
Hello Thabet,
If you directly hook up your "Osmocom Source" (or an equivalent) to a "Null
Sink", and if it still overflows, then your USB host is not keeping up. If it
stops overflowing, your CPU is not keeping up with your GNU Radio flowgraph and
you may have to either optimise your flowgraph
Hello,
I'm running a GNURadio app on my laptop with HackRF.
My sampling rate is 13.5MHz.
I have permanently overflow.
How can I check if it's due to:
- ADC overflow of HackRF hardware ?
- My laptop which is maybe not powerful enough ? (VirtualMachine: Ubuntu
18.04, 2 cores allocated i7 @3GHz, 4G
