Hi, I want to use one USRP to transmit and receive. I tried setting up two flowgraphs (top_blocks), one that will be a receiver "thread" and another a transmitter "thread". However the program complains:
RuntimeError: gr_top_block_impl: multiple simultaneous gr_top_blocks not allowed Is there no way to have a receiver flowgraph in operation while transmitting on a different daughterboard? In order to implement a TX+RX in one USRP do I have to shut down the receiver flowgraph every time I want to start up a transmitter flowgraph? I believe you can run two programs on the same USRP at the same time, e.g. TX: ./benchmark_tx.py -f 2.4G -v --discontinuous RX: /benchmark_rx.py -f 2.4G --rx-gain=90 -v which is pretty much the same as running two top blocks on the same USRP (although IPC is much trickier). Doing this however I run into the same problem as described in this thread, http://www.ruby-forum.com/topic/131602#new, where no packets appear to be received. -- Posted via http://www.ruby-forum.com/. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
