udpreceive
Networking Max messages via UDP
The simplest way to communicate over the internet in Max is by sending Max messages as UDP packets. The udpsend and udpreceive objects make that very easy. Tell the udpsend object what IP address to send to and what virtual port number to use, and tell the udpreceive object on the other computer the same port number.
TouchOSC data via wireless UDP
You can send messages to Max wirelessly from a mobile device such as iPhone, iPod Touch, iPad, or Android-based smart phone or tablet, using the TouchOSC app.
