Am trying to make data(read from keyboard) into packets, save this into a file, and in another program, read this data, deframe it and display.
I followed similar steps as in benchmark_rx and benchmark_tx. instead i removed modulator and demodulator. I alos avoided the use of usrp in between, instead of which i use a file to write to and read from. http://www.nabble.com/file/p24550834/check.py check.py 1) check.py asks you to the data u wanna send, converts it into packets and saves them into packetizer.data http://www.nabble.com/file/p24550834/functions.py functions.py it uses the file functions.py 2) check2.py is does teh deframing job http://www.nabble.com/file/p24550834/check2.py check2.py http://www.nabble.com/file/p24550834/chk_rxpath.py chk_rxpath.py http://www.nabble.com/file/p24550834/deframe_pkts.py deframe_pkts.py Running check2.py gives me the following output : 1) I am inside 'if __name__ = __main__' loop 2) Main() function is called now Defining tb with rx_callback 3) inside my_top_block in chk_rxpath now printing rx_callback : <function rx_callback at 0x2a71170> is this self.u being called? inside deframe_packets now inside queue watcher now rcvd packet in queue watcher : <gnuradio.gr.gnuradio_swig_py_runtime.gr_msg_queue_sptr; proxy of <Swig Object of type 'gr_msg_queue_sptr *' at 0x2a6b4c0> > callback in queue watcher : <function rx_callback at 0x2a71170> inside queue watcher : next is self.start() inside run(self) of deframe packets Connecting source file to packet_receiver connected <chk_rxpath.chk_rxpath object at 0x2a6b2b0> <gr_block file_source (6)> next is tb.start() terminate called after throwing an instance of 'std::invalid_argument' what(): port number 0 exceeds max of (none) Abort trap ~/gnuradio-examples/python/audio/> I did not follow where exactly i am going wrong!and what is happening when tb.start() is executed!! -- View this message in context: http://www.nabble.com/Packet-mod-demod-race-condition--tp12660275p24550834.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
