i try to work on this also but i still cannot put fftsink_nongl.py and
benchmark_tx or benchmark_rx together.. the problem i face is benchmark_*
have its own flowgraph which use .start and .wait for it to run.. i.e
tb.start and tb.wait while fftsink_nongl use stdgui2.stdapp and Mainloop to
run.. i.e
app = stdgui2.stdapp(app_top_block, "USRP FFT", nstatus=1)
app.MainLoop()
when i run tb.start or tb.run and tb.wait, it seem that my fftsink_nongl
that i had connect with usrp_source in the first place is stopping..
so can any body help me on combining this two system together? how to run
this two flowgraph together? what i want to do is i want to sense the
spectrum using fftsink_nongl.py and looking for spectrum hole and access the
hole by using benchmark_tx and benchmark_rx..
thank you in advance
