react-native-ir-manager

react-native-ir-manager

A react-native interface for using the 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

1. 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 the getPackages() method

1. 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'))
   

2. 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() {
    const SAMSUNG_TURN_ON_PRONTO_CODE = '0000 006d 0022 0003 00a9 00a8 0015 003f 0015 003f 0015 003f 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 003f 0015 003f 0015 003f 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 003f 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0040 0015 0015 0015 003f 0015 003f 0015 003f 0015 003f 0015 003f 0015 003f 0015 0702 00a9 00a8 0015 0015 0015 0e6e';

    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.
