Hi, I have several processing chains I need to switch in and out of my flow graph. What I have is several chains that look like
filter1->quad_demod1-> ... filter2->quad_demod2-> ... Can I not connect the chains together first and then just switch them in and out ? Say chain 2 was the one connected to the source as usrp_source -> filter2 -> ... Can I not switch to chain 1 by top_block->lock(); top_block->disconnect(usrp_source, 0, filter2, 0); top_block->connect(usrp_source, 0, filter1, 0); top_block->unlock(); When I try to connect the chains together at startup I'm getting a seg fault with the following line. Its the first line where I connect the first chain together. top_block->connect(filter1, 0, quad_demod1, 0); What am I not understanding about this? thanks Steve _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
