Hi all I'm testing ZMQ streaming with GRC and E310 It was succesful local loopback test with ZMQ_src and ZMQ_sink on development computer But when I python zmq_srcpy on E310 USRP , I got error It's not easy for me to understand what this message mean Traceback (most recent call last): File "gmq_srcpy", line 66, in <module> main() File "gmq_srcpy", line 55, in main tb = top_block_cls() File "gmq_srcpy", line 32, in __init__ selfzeromq_pub_sink_0 = zeromqpub_sink(grsizeof_gr_complex, 1, "tcp://127001:60", 100, True, -1) File "/usr/lib/python27/site-packages/gnuradio/zeromq/zeromq_swigpy", line 105, in make return _zeromq_swigpub_sink_make(*args, **kwargs) TypeError: pub_sink_make() takes at most 5 arguments (6 given) Regards Kim taeyeong

Hi Kim, In the generated Python file "gmq_src.py", you need to edit the line: self.zeromq_pub_sink_0 = zeromq.pub_sink(gr.sizeof_gr_complex, 1, "tcp://127.0.0.1:60", 100, True, -1) to be: self.zeromq_pub_sink_0 = zeromq.pub_sink(gr.sizeof_gr_complex, 1, "tcp://127.0.0.1:60", 100, True) Note the removal of the last parameter ", -1". This is due to mismatch of GNU Radio version between your host where you generated the Python file and the version running on the E3xx. The Application Note linked below covers using the ZMQ sinks with the E3xx to stream processed audio from the E3xx to the host and might be useful for reference and uses the XMLRPC blocks to adjust freq/gain/etc. https://kb.ettus.com/Streaming_processed_data_from_the_E31x_with_GNU_Radio_and_ZMQ Regards, Nate > On Jun 26, 2017, at 11:34 PM, 김태영 via USRP-users <usrp-users@lists.ettus.com> wrote: > > Hi all > > I'm testing ZMQ streaming with GRC and E310. > It was succesful local loopback test with ZMQ_src and ZMQ_sink on development computer. > But when I python zmq_src.py on E310 USRP , I got error. > It's not easy for me to understand what this message mean. > > > Traceback (most recent call last): > File "gmq_src.py", line 66, in <module> > main() > File "gmq_src.py", line 55, in main > tb = top_block_cls() > File "gmq_src.py", line 32, in __init__ > self.zeromq_pub_sink_0 = zeromq.pub_sink(gr.sizeof_gr_complex, 1, "tcp://127.0.0.1:60", 100, True, -1) > File "/usr/lib/python2.7/site-packages/gnuradio/zeromq/zeromq_swig.py", line 105, in make > return _zeromq_swig.pub_sink_make(*args, **kwargs) > TypeError: pub_sink_make() takes at most 5 arguments (6 given) > > > Regards > Kim taeyeong > <zmq_src.png><zmq_sink.png>_______________________________________________ > USRP-users mailing list > USRP-users@lists.ettus.com > http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
