如何创建Arduino / Raspberry pi api？

Question

I always want to create an API which lets me send value over the internet to an specific Arduino board or raspberry, I know that I can do it with a third party Server like> https://www.teleduino.org/ or https://www.yaler.net/ or if I use Raspberry I can install it Android and send data through GCM. But I don't want to use any other server, I already have a PHP hosting.

I think that I need to open a XMPP port or something to call directly the Ethernet shield or the the raspberry pi IP.

Will I need a static IP.

Any suggestions?

You want to write you own PROTOCOL, it can be based or use other protocol. If you have complete access to server, my suggestion is to use TCP Socket direcly (Client class on arduino with write e read, like using the Serial), if you can't then you have to "tunnel" your PROTOCOL over an accepted protocol on the server. If it has php then the protocol il HTTP, witch is based on TCP. see http://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Example_session
