[Discuss-gnuradio] Clean remote kill of python flowgraph

[Nowlan, Sean]

Hi all,

 

I would like to be able to remotely terminate a running Python-only flowgraph (no GRC). I basically set up the XMLRPC server to call “stop()” and “wait()” on the flowgraph object instance, but it leaves the USRP LO up. I would like the radio to be torn down completely.

 

Looking at gr_uhd_usrp_sink, it appears that the “stop” method overrides gr_top_block’s by sending an end-of-burst message to UHD, but apparently this isn’t doing the trick. Any advice?

 

Thanks,

Sean
