iOS Iphone Communication Protocols - communicate with other devices

[Qouipat]

Hi,

I'm trying to figure out how I can write an app that communicates with other devices. What possibilites are there? And which kind of devices can one communicate with through the IOS 4S?

Am very graceful for feedback!

Bluetooth?

Sure bluetooth, or maybe also through the bottom input of the phone..

What kind of other devices? Are they network connected?

The communication methods that do not require joining the MFi program include cellular data to a server with a public IP, WiFi using a local access point, audio (FSK, etc.), BluetoothLE, Bluetooth (to keyboards and headsets, or at least devices capable of pretending to be such), and MIDI (via the Camera Connection kit). Perhaps also the display or LED flash and the camera (there appear to be a couple apps in the App store than claim to communicate via blinking in Morse Code).

General Bluetooth data, USB, serial and other ports on the bottom of the iPhone are off-limits to apps on stock OS devices unless you somehow manage to join Apple's MFi program, which appears to be not easy.

Thank you for all the feedback!

I was more thinking like how can I write an app that lets me control other devices (like my mac, pc, television etc)? Are there any general communication protocols that I can use as API for this purpose, or am I limited in my choices?
