Hi Jay - enclosed is the second part of your flow chart - it was easy to cut it out and paste in a separate flowgraph.
I fed the flowgraph with a wave file instead of using the output from the first part.
The message debug works.
The only block with is blabbering is the Squelch. If you switch it between the "pass through" and "enable" positions, you'll see the PDU debug messages in the time frequency plot.
The problem may be in the first part of the flow graph.
Otherwise, I have no idea what you're doing or why you're doing it.

Hi all,
I am sending messages from an external application via (ZMQ PUSH) and received those messages in the GNURadio via ZMQ Pull message source.
From the ZMQ PULL side, I had correctly debugged the message coming from external applications.
I want to basically transmit those messages. But in the receiver side after the Tagged stream to PDU -> message debug block don't print anything. I put a QT Freq sink to check if the data is coming properly or not.
Did I miss something? How can I properly debug the messages. I had attached my flow graph.
Any suggestions are welcome.
With Regards,Jay Patel
