Hi all,
Memory: 1008.6MiB
CPU: Processor 0: 2.8GHz and Processor 1:2.8GHz
OS: 2.6.27.23-78.2.50.fc.i686 (Fedora 9)
GNU Radio: neither 3.1.3 nor 3.2. (I
download the gnuradio in the trunk several months ago.)
I have two machines, A and B ( the same systems as shown above).
I would like to send out signals periodically
(every 4.5ms) from A to B in the MAClayer of the tunnel.py in the
gnuradio-examples folder. I
implemented this idea after the “while 1” in the “main_loop” for MAC. It took a
while (a
few hundreds millisecond) to repeat the loop. I think that Python might be too
slow to be implemented the periodic signals so that the tunnel.py could not send
the signal every 4.5ms. Right? Can anyone give me some hints to let me know if
I can send out the signal every 4.5ms in tunnel.py? I would really appreciate
any suggestions..
Thank you,
Jane
Codes
in tunnel.py:
while 1:
now=datetime.datetime.now()
now_second=now.second
now_usecond=now.microsecond
now_time=(now_second)*1000000+now.microsecond
print "While_1 now_time =
%d" % (now_time)
# send out a packet to a client here
Results
of Print:
While_1 now_time = 20754893 microsecond
