Hi Mallesham, please make sure you keep the list, discuss-gnuradio@gnu.org, in CC when replying!
I think the best way to help you here is to point you at the official guided GNU Radio tutorials, http://tutorials.gnuradio.org , which do explain the handling of messages and how you can instead write data to a file. You might need to write a bit of python. Best regards, Marcus On 01/16/2017 09:39 PM, Mallesham Dasari wrote: > Hi Marcus, > > Thank you very much for the response.
