How long it takes for the Metafile Sink to began recording data?
I have a "No GUI" script that is a simple USRP source, throttle, and metafile sink. All have a 1M sample rates; the metafile sink has a relative rate of change of 1, 1M segment size, and have a detached header.
I start my script up I get the usually GNU Radio feed back (e.g. "Opening a USRP2/N-Series device..."), I get the "Press Enter to quit:", however post processing of collected meta data has shown that I can not immediately start my data collection as it won't collect the leading edge of the signal, I need to wait several seconds before proceeding. Why does this happen and is it possible to get a prompt on when the metafile sink has started recording?
