Socket Server to send strings/data from lan to serial ?

[unic]

Hello,

iam not very good in C. I used an arduino to build a remotcrontroller interface for my Iphone with NETIO app. My problem is that the arduinio ethernetdevice is to slow to get all the informations from ethernetsocket in realtime.

My idea was to use the raspberry PI as a bridge. collection the Data from Ethernet (wifi) Socket, change / splitt the information and send the to the arduino over usb ftdi converter or the uart pins from the raspberry.

As iam realy new to raspberry i want to now how i can start. does someone have examplecode were i can start with ? maybe a good book with the needed informations would be great too.

I Think its more a Linux thing that a raspberry beside of the UART-Interface.

Maybe its a good idea to use phyton for this ?

thx for help!

Probably easiest in Python, yes. I don't have much experience with that, though.

These code examples might help you getting the project started if you decide to do it in C.
For communication with a socket: http://www.linuxhowtos.org/C_C++/socket.htm
For serial communication: http://www.teuniz.net/RS-232/

Both code examples shouldn't give you trouble on the Pi. Good luck!

Well, it depends.
Mainly on how fast it would be. Uart is always bottleneck and you'll have to set and control size of read and write buffer and work with that buffers from different threads.
queue.Queue will do that for you, so I would use it.

So on one side socket, as was mentioned, because it can handle only one client (or make raspberry be the client).
In middle Queue
And on otherside pyserial.

And hey, as I looked to pyserial documentation, there is example code for that (and without queue): http://pyserial.sourceforge.net/example ... ial-bridge

hello,
can i communicate using socket between pc(windows) and raspberry ??

Hi,

can i communicate using socket between pc(windows) and raspberry ??

Yes, of course.
I have doubts that there is any computer/OS capable to communicate over Internet and at the same time not "offering" sockets communication.
