Is it possible to communicate with an Infrared device (USB Infrared, TV, Mobile Phone, etc) using iOS (iPhone or iPad)?
Well, i know it's possible, since there are many remote/universal remote applications in the AppStore. I basically want to know how?
- What are the limitations and requirements?
- What kind of additional hardware is required? If it's available in the market?
- Which protocols should i know about?
- Which iOS libraries can help me in the process.
Can anyone point me in the right direction. Thanks.
回答1:
Any devices using IR for controllers are either wifi or have custom hardware that outputs IR signals based off of output from the device. So without using your own hardware, I don't believe this is possible
回答2:
Infrared isn't unbuilt in iPhone. All those remote apps are wifi based.

The hardware isn't available but there is a hack you can make to the headphone socket.

There is no infrared connectivity within iOS.However there are bluetooth and wifi.Generally you can use bluetooth functionality by importing GameKit framework.Thanks
