Re: [Discuss-gnuradio] blks2.mod, blks2.demod

[udadidd]

I have used some print commands in these programs to follow the flow of the
code. I used print commandsin a) benchmark_rx, b) receive_path c)
blks2impl/pkt.py d) packet_utils.py.
Running the program is get the output as follows : 

1) In main now
2) in def main() now
3) calling tb in main()
4) in receive_path now
5) calling __setup_usrp_source
6) inside _setup_usrp_source: getting self.u now
usb_control_msg failed: usb_control_msg(DeviceRequestTO): pipe is stalled

making packet_receiver module...i will call pkt.py here
>>> gr_fir_fff: using SSE        # Here the pkt.py must be called
>>> (demod_pkts() ), but instead it does not show me any output from pkt.py
made packet_receiver module....
options.log_rx_power = false
executing self.connect of self.u and packet_receiver
tb.start() in a while     # I did not follow what exactly happens when
tb.start() is called? and what is the flow here?
tb.wait() now
in def rx_callback now

ok =  True  pktno =    0  n_rcvd =    1  n_right =    1
in def rx_callback now
2
ok =  True  pktno =    1  n_rcvd =    2  n_right =    2
.

.

I made changes in the
/usr/local/lib/python2.x/site-packages/gnuradio/blks2impl/pkt.py
and /usr/local/lib/python2.x/site-packages/gnuradio/packet_utils.py files
