UDP transmissions possible?

[koenti]

Before I dig into the SDK, I have the following situation and questions.

My house is controlled via a KNX/EIB (European standard) domotic system. It has also a EIB-LAN interface where I can control my complete house (HVAC, lights, gates, ...) from PC. As software developer I wrote some PC tools which send UDP messages over my LAN to my EIB-LAN interface.

Question1: Can I create and send UDP messages via custom software on my PCH, and control it via web interface on PCH?

Question2: What method is the best to exchange data/status information between my PCH and eg my LAN PC which runs:
a) windows web service
b) web server

(question2 is alternative solution when question1 is not possible )
regards,
Koenti

Answer1: Shouldn't be a problem, as it is a normal linux system with sockets as usual!... as long as you have installed/created a crosscompiler from the toolchain provided by Syabas and you have enough knowledge....

The PCH runs apache webserver with PHP... and running shell commands should work...

Answer2: Obsolete by answer 1.

Thanks for the feedback. "Enough Knowledge", hmm not today on that platform but I may build it up ... . What are the good resources on the web to start building this knowledge (overview software tools, "hello world" examples, tutorials, ...)?

There exists a lot of linux examples everywhere!

if you don't have a linux system I'd suggest you set up one and test out some simple c-applications.

It sounds as if you will manage! =)

learning linux is fun!
