I tried modifying the gr-osmosdr source to add the message sink in the
source_impl.cc. Turns out, we cannot have message passing in hierarchical
blocks as discussed in this post:
https://lists.gnu.org/archive/html/discuss-gnuradio/2016-01/msg00291.html
and this one:
https://lists.gnu.org/archive/html/discuss-gnuradio/2015-10/msg8.html
Now, what other options do I have? Is it possible to connect to a message
port insde the hierarchical block from outside?
Warm regards,
