I was vague because I've no limit about the operative system ecc ecc. In my mac I've both windows and mac, and I've access to several tvbox android, so I can do whatever I want, the important think is that I can put data from sensor on a web page (local) so I can get those data via wifi and put in an ios app that I've to develop.
Btw if there is no real difference, I want to get sensor data from an arduino, receive via usb serial data, put on a local web server, and get those data in order to use with an ios app.
