What device/model are you using? That way I can try to replicate the issue. Those methods above all cause streamers to be created/destroyed. So there may be an issue w/ cleanup or init. Also.. Are you using lock()/unlock(), stop()/start() to dynamically reconfigure the flow graph at runtime? If that is the case, you may have better luck with the stream selector in grextras which can re-route streams on the fly: https://github.com/guruofquality/grextras/wiki#wiki-list-of-blocks-in-this-project -josh > > Thanks so much. > > LTP. > > > > _______________________________________________ > Discuss-gnuradio mailing list > [email protected] > https://lists.gnu.org/mailman/listinfo/discuss-gnuradio > _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
