etherned udp checksum

Hello, I'm new to arduino. I'm developing a small application on arduino 2 with ethernet connection to download data. At the moment I use UDP protocol to connect to the application, but I'm new to arduino and I don't understand if Arduino UDP library automatically handle optional checkum over UDP protocol. Thanks

No one can help me ?

If you provide the necessary information, we might try to. Please read the sticky post a the top of the forum topic.

All Arduino code is open source, so look through the library code to see if a checksum is implemented.
