Dear all,
In my application, I want to implement the following feature:
1. If I decode 50 packages, then stop the flowgraph immediately
2. otherwise, if after 30 seconds, I cannot receive more than 50
packages, then stop the flowgraph. So I could prevent the flowgraph from
lockin

Hi Marcus,
That explains it. Thanks for the help.

I haven't seen a reply to this posting, so you're getting my "Mac OS X /
MacPorts"-centric view.
MacPorts has been using WX >= 3.0 for quite a while now; currently at
3.0.2. I've done extensive testing with version 3.0 of WX and GNU Radio,
and found nothing incompatible that wasn't already an issu
Hi Peter,
the metadata is stuffed into PMT dicts, which get serialized by pmt's
serialization routines.
Now, these are a bit peculiar on serializing multibyte things. They
generally ensure big-endianness, if I understand the code [1] correctly.
The sample portion would have the same endianness as

Thank you very much for your reply.
I took a look at the examples you referred to, but the OFDM bits become a
little bit distracting for me. Actually, in my system, I use a simple QPSK
modulation. I already used the correlate and sync example to do some things.
I insert a preamble using the stream
Hi All,
I have a USRP N210 with RFX2400 2.3-2.9 Ghz RX/TX. I have recorded a trace
at 2.41 GHz and stored it to a file filename.dat. I want to transmit the
same trace at 2.415, 2.420, 2.425 so on till 2.440.
So, I used the freq_hopping.py python utility under the python examples
folder in gnuradi

The info Chris sent along has helped to move this along although at this
point I still don't have a solution or a root cause.
The library that issues the error message is

I'm making much more progress on my embedded x86_64 gnuradio project.
I am now able to build and run my grc-created python app, but I get
this error. I'm using some counter/sliders from Qwt (Qt GUI Range
block) to be able to change some values interactively. However, I
don't seem to have PyQt4.Qw
