[Discuss-gnuradio] Absolute time reception through python interface

[Nicholas Lan]

Hello,

 

I am able to use UHD C++ code to have an ettus device record data at a specified absolute time. I am trying to implement this functionality in python. I have read in a discussion topic that the recv command used in C++ to start receiving at a specified absolute time is not implemented through SWIG in gnuradio and that gnuradio scheduler should be used instead. I have looked through the code files including ‘scheduler’ in gnuradio as well as gr_flat_flowgraph and can’t see how to implement an absolute timed start through these codes. I also looked at gr_timer but read that this is not currently fully implemented. Could someone point me in the right direction in terms of starting reception at a specified absolute time through gnuradio/grc please?

 

Thanks in advance

Nicholas Lan
