All,
ZeroMQ is/was quite popular, but its author redesigned it, created a much
cleaner implementation called “nanomsg”,
ref: https://nanomsg.org/documentation-zeromq.html
<https://nanomsg.org/documentation-zeromq.html>
ref: https://nanomsg.org/index.html <https://nanomsg.org/index.html>
And then he rewrote it again:
ref: https://nng.nanomsg.org/RATIONALE.html
<https://nng.nanomsg.org/RATIONALE.html>
and called it nng:
ref: https://nng.nanomsg.org <https://nng.nanomsg.org/>
So, in short, if one is interested in ZeroMQ and NuttX, I’d suggest nanomsg
would be a much more efficient replacement; and finally the best choice of the
three IMHO would be nng for an embedded system (Cortex-M3/4 class) system.
Just my $0.025, I hope it’s helpful.
Cheers,
-david
