Hi to all,
I have developed an iPhone/iPad app called iDatanet which lets you listen to a stream of UDP data off a specified port with a very simple protocol:
iDataNet@var1;val1@var2;val2@var3;val3 (… etc …)
In the app you can then configure various pages with displays showing the incoming pairs of variables (or labels) and values (which can be numbers or words). If you find this useful and have managed to use it with an Arduino board be sure to let me know!
Here is a video of iDataNet in action:
Thanks for your reply. Basically I selected UDP because of its radio broadcasting properties. No hand-shaking involved, just a UDP listener. Usually it is a lot easier to put in place and I am hoping that people will use iDataNet for any number of applications, in any number of fields. Thanks for the links you sent, they are very interesting. I understand the advantages of TCP but I opted for the simplicity of UDP, and the ease for people to program any device for sending data out.
