xPL.Arduino

Hi, I don't know if some of you are using the xPL protocol ( http://xplproject.org.uk/ ) ? xPL is an open protocol intended to permit the control and monitoring of home automation devices.

Here is an implementation for arduino : http://code.google.com/p/xpl-arduino/

Some Features: - No link with hardware, work with wiznet, ENC28J60, ... shields - Auto send heartbeat messages and answer to heartbeat request - Parse received xPL messages and send result to a callback define by you - Send xPL message

Hope it can help someone :) thanks,

Hi, thanks for sharing. We are watching this protocol for our domotic framework Freedomotic.com. Can it be used as a complete emulator? Thanks

Sorry, what do you mean by "complete emulator" ?

Hi,

nice project. I've done somenthing similar in the Souliss project where I've a protocol called MaCaco and a virtualized network called vNet. If you would, you may try to integrate your protocol over vNet to let different devices Ethernet and Wireless p-to-p 2.4 GHz communicating over your protocol, vNet manage the bridging and routing.

If I've understood correctly, your protocol is ASCII based. Am I right or is a binary one? Which is the RAM footprint?

Thanks.

Yes xPL is ASCII based. It’s a bit verbose so perhaps not the better protocol for a small embbeded system. But it’s already support by several home automation systems and devices. I think it’s good for interoperability.
I’m trying to do some optimization at the moment.
