Re: [Discuss-gnuradio] Trouble posting messages to block's message port

[Martin Lülf]

I had this issue once and if I remember correctly, connecting the block 
to the flowgraph (i.e. connect any block to your message port, even if 
that port will never send messages) will make your message handler react 
to messages from your python code.

Hope this helps
Martin
