You would need to make some kind of c++ app in gnuradio or maybe standalone to deal with the metatdata. I dont know another way.
Also, the uhd comes with an example app called rx_timed_samples.cpp, you may want to take a look at this to see how the api deals with the metadata. I will expand this example to include clock configuration when i get the chance as well.
I hope that helps, -Josh On 05/06/2010 12:35 PM, Criss Swaim wrote:
I have been working with the uhd version of gnuradio and have attached a gps unit to the usrp2 to set the pps. So far, I have not figured out how to extract the time (secs and nsecs) metadata for a signal sample. This is mostly due to my limited C++ coding skills. Has anyone successfully extracted the time metadata and would you be willing to share the C++ code to show me how to capture and extract the time metadata.
