[Discuss-gnuradio] Problem with "TCP Source" module in the client mode

[Igor Volodin]

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.


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
