The other option would be to use UDP and build a trivial UDP-accepting plugin for RabbitMQ, thus moving almost all of the complexity and memory-requirements onto the server. (Actually that'd be a nice feature to have in general.)<br>

And if rabbitmq-c is still too big, and all you need to do is publish messages from the tiniest client possible, you might want to look at STOMP - you could probably write a minimal publish-only client quite simply, and it would be pretty small.<br>

I'm not sure AMQP/rabbitmq-c client would be able to run on that<br>
constrained of a system (someone else on this list might correct me though).<br>
<br>
In general you're going to need a TCP/IP stack so you can connect to the<br>
broker, then enough memory to hold a couple frames (the minimum frame<br>
size is 4096 bytes). You could probably do it with smaller buffers but<br>
it's not something done with most client libraries.<br>
<br>
If that all will fit in your constrained system, I would probably pick<br>
apart the the rabbitmq-c library and pare it down to something that does<br>
the minimum you need. Then again I'm not experienced with development of<br>
embedded devices, so I'm not sure how people typically accomplish these<br>
things.<br>

- Does anyone have code for the simplest possible message producer?<br>
<br>
I would like to produce messages from a _very_ memory constrained<br>
embedded system*. Can anyone advise me on what the absolute minimum I<br>
have to do to produce and send a message is?<br>
<br>
Also, if anyone can point me towards what a simple "hello world"<br>
message template looks like, it would be appreciated. More details:<br>
I'm thinking of the sort of message that the Tutorials cover (eg:<br>
<a href="http://www.rabbitmq.com/tutorials/tutorial-one-python.html" target="_blank">http://www.rabbitmq.com/<u></u>tutorials/tutorial-one-python.<u></u>html</a>)<br>
<br>
Thanks in advance - I'm a Rabbit noob, apologies if this post is not<br>
using the correct terms.<br>
