Thanks for intervening, Frank.

ZeroMQ is a flexible toolkit for writing different communications
patterns, whereas MQTT is broker-based publisher/subscriber system.
Although 0MQ has pub/sub sockets as one of it's many patterns, the
wire format is different than that used by MQTT, so they are certainly
not directly compatible.
ZeroMQ sockets mostly just want to talk to other ZeroMQ sockets, so
for the majority of systems, you would write all your services using
just 0MQ. It does have some low-level interfaces to talk to the rest
of the world, but if you wanted to use them to speak to an MQTT
broker, you would essentially need to write an MQTT client library
using these interfaces. That is not a "light" solution.
If MQTT does everything that you need then just forget about ZeroMQ
and pick out an existing MQTT client. You will be up and running much
more quickly.
But if you already have a ZeroMQ platform running (or desire some ZMQ
patterns not supported by MQTT), and want to bridge some of it to
MQTT, then you can write a bridge app between the two systems. My
advice, in that case, would be to take the ZeroMQ library and an MQTT
client library, and write a program that shuffles packets back and
forth between them.

Hello,
ZeroMQ can do sockets, HTTP/Websocket/Telnet e.t.c. protocol
transports and this
can be done peer to peer. It would far more efficient to use MQTT
over 0MQ
Websockets for instance, in my view.
An MQTT to 0MQ bridge can be coded for instance, but I'm hoping
someone can
shed light on how to keep this as light as possible.

I don't. But doesn't ZeroMQ provide similar facilities to MQTT? Does it
make sense to run MQTT over ZeroMQ?
Secondly, the Paho embedded client is intended to make it easy to port
to different network interfaces. You have to write a very small module
for the network specific code, the rest stays the same.

Hello,
Does anyone have knowledge of an embedded MQTT client running over
ZMTPZWS/ZHTTP
or plain ZeroMQ sockets over TCP ?
