ZMQ PUB Message Sink

The ZMQ PUB Message Sink receives messages from a flowgraph and publishes them on a ZMQ PUB socket. A PUB socket may have many subscribers and will pass all incoming messages to each subscriber. Subscribers can be either a ZMQ SUB Message Source block or a non-GNU Radio ZMQ socket.

Parameters

(R): Run-time adjustable

Address

ZMQ socket address specifier. The format of the address is tcp://*:port where * should be 127.0.0.1 for localhost.

Note: If the Source and Sink blocks are on two different computers on the same LAN, then the IP and port number of the Sink block must be specified on each end of that connection. For example, if the Sink is on IP 192.168.2.14:5678 and the Source is on IP 192.168.2.5, both Source and Sink blocks must specify the Sink IP and port (192.168.2.14:5678).

timeout

Socket timeout in milliseconds, default is 100ms.

Example Flowgraph

In this example, a Message Strobe block sends the string "Demo" once per second.
