react-native-ir-manager
A react-native interface for using the Infrared (IR) transmitter in Android smartphones with ConsumerIRManager.
Getting started
$ npm install react-native-ir-manager --save
Automatic installation
$ react-native link react-native-ir-manager
or
$ rnpm link react-native-ir-manager
Manual installation
Android
- Open up
android/app/src/main/java/[...]/MainApplication.java
- Add
import com.danielr18.irmanager.IRManagerReactPackage;
to the imports at the top of the file - Add
new IRManagerReactPackage()
to the list returned by thegetPackages()
method
- Append the following lines to
android/settings.gradle
:include ':react-native-ir-manager' project(':react-native-ir-manager').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-ir-manager/android'))
- Insert the following lines inside the dependencies block in
android/app/build.gradle
:compile project(':react-native-ir-manager')
Supported Devices List
Most of the devices in this list should be supported.
Usage
import React, { Component } from 'react';
import {
AppRegistry,
View,
Button,
} from 'react-native';
import IRManager, { hasIrEmitter, transmitProntoCode } from 'react-native-ir-manager';
export default class RNIRTest extends Component {
hasIrEmitter() {
IRManager.hasIrEmitter()
.then(hasIrEmitter => console.log(hasIrEmitter ? 'Device has IR emitter' : "Device doesn't have IR emitter"));
}
getCarrierFrequencies() {
IRManager.getCarrierFrequencies()
.then(console.log)
.catch(console.log);
}
transmitProntoCode(prontoHexCode) {
IRManager.transmitProntoCode(prontoHexCode)
.then(console.log)
.catch(console.log);
}
render() {

return (
<View>
<Button onPress={this.hasIrEmitter} title="Has IR Emitter Support?" />
<Button onPress={this.getCarrierFrequencies} title="Log Carrier Frequencies" />
<Button onPress={() => this.transmitProntoCode(SAMSUNG_TURN_ON_PRONTO_CODE)} title="Turn on Samsung TV" />
</View>
);
}
}
AppRegistry.registerComponent('RNIRTest', () => RNIRTest);
hasIrEmitter()
Check whether the device has an infrared emitter. Promise returns a boolean.
getCarrierFrequencies()
Query the infrared transmitter's supported carrier frequencies. Returns an Array of Objects with the minimun and maximum frequency (inclusive) on which the infrared emitters can transmit
transmit(carrierFrequency : Number, pattern : [Number])
Transmit an infrared pattern. Promise returns a true
value if it gets transmitter.
transmitProntoCode(prontoHexCode : String)
Converts a Pronto Hex Code commonly found online to an infrared pattern, which is then transmitter. Promise returns a true
value if it gets transmitter.

This project used react-native-module-boilerplate as a base and it was a helpful way to get started.
