I’m currently in the process of porting my gr-drm project to the 3.7 API
and now I’m a little bit stuck and hope that someone here can help me.
I want to create a hier block (in GRC) that accepts vectors as input and
output. Their size is controlled by parameters like vlen_in and
Unfortunately, the IO size of the generated hier block always stays 1,
matter what I use as parameter. I attached a minimal (pure GNU Radio)
example flow graph and hier block that reproduces my problem. Maybe I
overlooked something obvious, but I don’t get why this is not working.
If someone had the time to try this and could report if it works (it
not for me), I would be very grateful.
I’m on Ubuntu 12.10 and have GNU Radio v22.214.171.124-116-ge751e54a installed.
