The ZMQ PUSH Message Sink block receives pmt messages from a message port and sends them through a ZMQ PUSH socket. It performs a 'bind' on the designated port. It will interoperate with a ZMQ PULL socket, either from a GNU Radio flowgraph or an external process.
This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary. Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.
 
As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

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.

The ZMQ PUSH Message Sink block receives pmt messages from a message port and sends them through a ZMQ PUSH socket. It performs a 'bind' on the designated port. It will interoperate with a ZMQ PULL socket, either from a GNU Radio flowgraph or an external process.

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
Receive timeout in milliseconds, default is 100ms.
