Re: [Discuss-gnuradio] GnuRadio File sink Operation, Need help

Hi Sumit,

that's kind of redundant -- you know the start time and you know the constant sampling rate, so you know the time of each sample in your file. Anyway, the metadata sink saves every tag you specify, so just write a block that calculates the time to a given sample number, and occasionally adds a tag to the stream.

Greetings,
Marcus

Thanks mleech,  I used Metadata but I am able to add date once at starting of Sinking but not able to add during whole process.

You could insert date/time tags.        Or, if the rates are quite low (a few Hz at most), you could use a probe, and have a poller function that grabs data from the probe, and      formats it all pretty like.  That's how simple_ra writes its data log files....              On 2014-09-05 11:06, Sumit Saluja wrote:    Dear All    I am trying one experiment but not able to complete it on Gnu Radio. I am reading Data from hardware and sinking with file. Now I am trying that at with every sample data and  date and time will be sinked in a file. Is there any option to do so.
