Hello.I want to control a led on/off from my pc with dyndns service and with arduino with connection sony ericsson mobile phone with Gprs (internet) or with gprs shield.Any idea?Thanks.
Have you tried dyndns with GPRS in your country? At least here it doesn't work because NAT is used on the provider side. I'd try first to setup such a system using a standard PC or Notebook and go to an Arduino setup if the PC worked.
Usually Arduino and GPRS are used only as a client, sending some data to the internet.
If i have a static IP works surely? I want to send and get data from arduino( control motors and sensors).
You get a fixed IP from your mobile provider? I also get a static (at least for some time) IP but it's in the private address range (10.x.x.x), so it must be address translated.
Anyway, If you have a server somewhere in the Internet, configure the Arduino as a client that sends it's data to the server and get the commands by pulling them from the server.
No mobile provider...I want to control a boat with arduino and gprs or 3G shield from my house via internet with static IP or dyndns...the mobile provider is for my gprs or 3G shield.
How far away from the house will the boat be? A direct RF link might be a better option.
?oo long I want to do with autonomous photovoltaic and take pictures and video something like NASA robots on Mars but the sea ...i think this is good http://www.cooking-hacks.com/index.php/documentation/tutorials/arduino-3g-gprs-gsm-gps#step10
No mobile provider
You have to describe how you wanna use GPRS or 3G without a mobile provider.

Don't use an Arduino for videos, it's simply not fast enough. I guess you'll get more lucky with one of the embedded linux devices. Take a look at the RaspberryPi. Is WiFi an option for the wireless transmission?
You might be able to use a Arduino as a control / alert system. GPRS is an option but you need to have a mobile service provider, a M2M contract, and coverage. The arduino would not have to process the video, etc. For example, based on external inputs such as an alarm going off it could simply open the GPRS connection for a standard IP camera to connect to the internet with, transmit the picture to a server, send you an SMS / e-mail with an alert, and close the connection.
I doubt you'll be able to stream video - speeds are usually too low and most M2M contracts that allow a lot of data are expensive. The kind of video you could stream would likely be pretty useless (i.e. little resolution and lots of compression). If high-quality video is what you want, I suggest getting someone nearby to let you use their WiFi network.
