Hello all, as promised my experiences: Using ZeroMQ works really cool and out of the box. So good that I dropped the option proposed by Kevin (sorry).
I share some (now somewhat trivial) notes, if somebody else (with equally few experience) wants to try: * On Ubuntu you have to install libzmqpp-dev (and dependencies) and then re-cmake and re-build GR, as Marcus pointed out. * The address field does not resolve domain names * REQ = Client, REP = Server * your port number must larger 1024 (<1024 are root use only ports) * Due to Ubuntus firewall settings (iptables) incoming connections are blocks => the IP address of REP(Server) must be the IP in the address field. Thanks to Marcus and Kevin again.

Meanwhile I also recognized pmt::serialize, which I found awesome. And Marcus pointing to ZeroMQ was even better. I will try both and report back.

ZeroMQ is a world of its own; if you want a single point-to-point connection, try the REP sink and the REQ source, with an address like tcp://<ip address of your computer>:5555 in both. If you want a publisher/multi-subscriber thing, have a look at the pub/sub combination. There's examples, typically in /usr/share/gnuradio/examples/zeromq Best regards, Marcus On 06/26/2015 07:20 AM, Ludwig Stephan (CR/AEH4) wrote: > Hello list, > > I kindly ask for an idea how to transmit a pmt::cons via a tcp (or udp) > connection?
