Mobile application using IR emitter with Delphi XE5 or higher

I think I understood your idea, you want to make a kind of universal control for your home and operate it by cell phone.

If it is to sell the application, I suggest you make an infrared emitter that works with the network and that you operate the same by the WiFi of the phone, because most of the devices today do not have this hardware included.

But if it's for specific use this has already been done just look in the Play Store you find several of them.

Regarding Delphi, I believe there is more literature and documentation for Java.

Take a look at this and look for more videos about it. link

In Java I have:

Infrared Transmitters

When running on a device that includes an infrared (IR) transmitter, you can now transmit IR signals using the ConsumerIrManager APIs. To get an instance of ConsumerIrManager, call the getSystemService () method with CONSUMER_IR_SERVICE as the argument. You can then query for supported IR frequencies of the device with getCarrierFrequencies () and transmit signals by passing their desired frequency and signal pattern with transmit ().

You should always first check if your device includes an IR transmitter by calling the hasIrEmitter () method, but if your application is only compatible with devices that have one, you must include an element in your manifest for "android.hardware. consumerir "(FEATURE_CONSUMER_IR).
