Hi,
first of all please make sure that you reply to the list rather than to
the individual persons, or CC the list so that answers are also available
for anyone who might have a similar question in the future.
The question how to do a block connect is confusing me a bit. Maybe there
is a misunderstanding? You should already have done block connections when
setting up your flowgraphs.
Anyway what I mean is a standard connection of two GNURadio blocks, so in
GRC it might look like this (I know I am not an ASCII artist, sorry)
|---->(Your signal processing block)
(UHD Source)-----|
|---->(File Sink)
This should lead to python code like this
##################################################
# Blocks
##################################################
self.uhd_usrp_source_0 = uhd.usrp_source(...)
self.yourblock_0 = yourmodule.yourblock(...)
self.file_sink_0 = gr.file_sink(gr.sizeof_gr_complex*1, ...)
##################################################
# Connections
##################################################
self.connect((self.uhd_usrp_source_0, 0), (self.file_sink_0, 0))
self.connect((self.uhd_usrp_source_0, 0), (self.yourblock_0, 0))
Yours
Martin
