react-native-infrared-interface

A React Native interface for using Infrared (IR) transmitter in Android devices

Installation

npm install react-native-infrared-interface

Usage

hasIrEmitter(): Check whether the device has an infrared emitter

import { hasIrEmitter } from 'react-native-infrared-interface';

// ...

const hasIr = await hasIrEmitter();

// returns a boolean value
// may also return null

getCarrierFrequencies(): Query the infrared transmitter's supported carrier frequencies

import { getCarrierFrequencies } from 'react-native-infrared-interface';

// ...

const carrierFrequencies = await getCarrierFrequencies();

// return value will be an array of objects
// containing the minFrequency and maxFrequency of each frequency (in Hertz)

transmit(carrierFrequency, pattern): Transmit an infrared pattern

• carrierFrequency: The IR carrier frequency in Hertz.
• pattern: The pattern to transmit.

import { transmit } from 'react-native-infrared-interface';

// ...

const deviceCommand = '7723 6933 882 186 345 987 162 876 110 188 648';

// ...

const transmitResult = await transmit(38000, deviceCommand);

// returns true when successfully executed

Example app

This library's repository also includes an example app that demonstrates usage of the library. You need to run it to test any changes you make.

Not available for iOS

This library doesn't have any implementations for iOS as Apple devices do not have IR blasters.
