Understanding ZMQ Blocks
This tutorial is under construction.
This tutorial presents the GNU Radio ZMQ blocks. It is a set of six Source Blocks and six Sink Blocks. The naming convention follows other source and sink blocks in that a source block provides data entering a GNU Radio flowgraph and a sink block sends data out of the flowgraph. It is a flowgraph-oriented perspective.
From the ZeroMQ website: "ZeroMQ (also known as ØMQ, 0MQ, or zmq) looks like an embeddable networking library but acts like a concurrency framework. It gives you sockets that carry atomic messages across various transports like in-process, inter-process, TCP, and multicast."
Types of ZMQ Blocks
The two basic groups of ZMQ blocks are those which transport stream data, and those which transport text strings. They are described below.
