Sink the contents of a msg port to a ZMQ PUB socket.
Receive messages on ZMQ SUB socket and source stream.


This block acts a message port receiver and writes individual messages to a ZMQ PUB socket.
This block will connect to a ZMQ PUB socket, then produce all incoming messages as streaming output.
A PUB socket may have subscribers and will pass all incoming messages to each subscriber.
Subscribers can be either another gr-zeromq source block or a non-GNU Radio ZMQ socket.

Receive messages on ZMQ SUB socket and source stream.

This block will connect to a ZMQ PUB socket, then produce all incoming messages as streaming output.

Parameters

(R): Run-time adjustable

Address
ZMQ socket address specifier.
Timeout
Receive timeout in milliseconds, default is 100ms, 1us increments.
Pass Tags
Whether source will look for and deserialize tags.
Hign Watermark
High Watermark to configure the socket to (-1 => zmq's default)

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
