I added the ability to have multiple pads a few months ago. I believe that it works. Make sure that your git clone is recent enough ( im not sure about the version) and make sure that there is not this issue of multiple gnuradio installs (and possibly importing old grc modules).

Is GRC able to create Hierarchical Blocks with more than one Sink / Source?

I tried to create such a Hierarchical Block in the following way which failed:


In a blank GRC-File, I assigned in the Options-Block ID (hierblocktest), Title (hier block test), Generate Options (Hier Block) and Category (Custom).

I added two Pad Sources and two Pad Sinks, connected them (connect(source1,sink1), connect(source2,sink2)), generated the flow graph and restarted GRC.

To test the block, I added it to a new sheet. The Block is displayed as if it had just one Sink and one Source.

I am using GNU Radio Companion 3.3git-696-g1ae689ff.
