Yes, sounds like a bug. How did you install GNU Radio 3.10.3.0 on Debina 11 (bullseye)?

Referring to a block by a specific name
Hi, I have some python snippets within the GRC that refer to certain blocks. However, the GRC generated names can be quite unintuitive (like blocks_stream_to_vector_1_0 etc.) . I was wondering whether it is possible to refer to certain blocks by user-defined names. I understand that there is an alias option in each block's GUI that corresponds to a set_block_alias() call in the top_block python script. Apparently there is a block registry ( https://github.com/gnuradio/gnuradio/blob/main/gnuradio-runtime/lib/block_registry.cc) that allows you lookups by alias but I could not figure out how to do that in python. What is the recommended approach for my scenario? Any help would be much appreciated. Best regards, T.K.
Re: Referring to a block by a specific name
Hi T.K. First you have enable the "Show All Block IDs" in GRC, then you can change the ID of the block to whatever you want it to be. In the snippet, then just refer to the block as self.blockname Hope this helps.
