[Discuss-gnuradio] Process a vector of samples while flowgraph is running

[Germano]

Hi,

A couple of digests ago I read about getting data from a running 
flowgraph using probes.
I have a flowgraph that gets samples from an hardware source, filters 
and decimates, and then sends samples to graphical sink.
The thing is, I want to be able to grab samples from the running 
flowgraph to make some calcs.
I tried to use a probe to grab samples and a xmlrpc server to send them 
to another script where I have the algorithms. Everything worked as 
expected.
When I tried to use the same logic with vectors (stream to vector -> 
vector probe) and pass the vector using xmlrpc, in the client side, it 
shows this error: xmlrpclib.Fault: <Fault 1: "<type 
'exceptions.TypeError'>:cannot marshal <type 'complex'> objects">

I read xmlrpc docs and eventually it doesn't support tuples or even 
complex values (the vector I grab from the flowgraph is a tuple of 
complex tuples, I guess).

Is this the correct way to grab a vector of samples from a running 
flowgraph to process them using another python script? Would you suggest 
anything different?

Regards, great job,
