Two issues in GNU Radio companion.
I’m working on a hier_block in GRC and want it to have multiple outputs.
When I generate the block, though, I get a few problems. First, only one
output pad is exposed. Looking at the generated XML file, I see that
one source block is being created (I have four pad sinks). When I look
the Python file, the io signature for the output is correct, but any
to the output are all (self,0), so there seems to be no distinction of
pad sink is being used.
When I hand-edited the files to what they should be, the block works
Is this a bug or am I doing something wrong?
Also, when I double-click on a QtGui sink, I get this message in my
Traceback (most recent call last):
