Hi all!
I am trying to build following simple scheme:
Signal source --> TCP Sink (server mode) <---- TCP Source (client mode)
--> GUI Scope Sink
It's strange but this simple scheme isn't working.
Are you running both sub-flowgraphs in the same GRC canvas? I just tried
this in 2 canvases and it works. It *should* work from one, but I'm not
sure GRC is setting things up right.
In any case, try 2 canvases.

sockstat shows me:
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
igor python2.7 56206 11 tcp4 10.21.32.6:21950 10.21.32.6:12000
Looks like communication between tcp sink and tcp source blocks has been
established, but tcpdump doesn't show any packets
I decided to check first part of my scheme (Signal source + TCP Sink),
and connected using netcat utility to the tcp sink port. All looks OK,
the values come as expected.
Can anybody explain, why this simple scheme doesn't work?
Best regards,
Igor
