Are there any plans to add support for the DatagramSocket?
I don't know if there's anything equivalent for the iPhone but basically I'm looking for a way to send and receive messages in an app via UDP.
There is a UDP module in the public modules repository now. It supports both iOS and Android, and lets you send packets to specific addresses or broadcast them out. You can also receive packets, and read their data as strings or as a byte array. This was created in the last several weeks, so please bear with any issues mass use uncovers! Feel free to send in pull requests for any fixes or enhancements you want to make to the module. Cheers!
(Note: If you are using Android with Ti SDK 1.7.5 or earlier, you will need to use the apilevel_1 branch of the above repository! The master branch is for 184.108.40.206 with dual runtime (V8 and Rhino) support.)
For others who want UDP support, Chris created a udp module for iOS.
