react-native-nmea-library v1.0.1

react-native-nmea-library

What is this odd place?

If by any chance you need a an ability to access NMEA data on Android devices from React Native you can use NMEA library.

• Supports Android only.

Getting started

$ npm install react-native-nmea-library --save

Mostly automatic installation

$ react-native link react-native-nmea-library

Manual installation

Android

1. Open up android/app/src/main/java/[...]/MainActivity.java

• Add import com.reactlibrary.RNNmeaLibraryPackage; to the imports at the top of the file
• Add new RNNmeaLibraryPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-nmea-library'
   project(':react-native-nmea-library').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-nmea-library/android')

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-nmea-library')

Usage

import RNNmeaLibrary from 'react-native-nmea-library';
import {DeviceEventEmitter} from 'react-native';

...

componentDidMount()
{
    RNNmeaLibrary.start();
    
    DeviceEventEmitter.addListener('onNmeaReceive', (event) => {
      console.log(event);
      
      // will output:
      // { 
      //   timestamp: 1543940192000,
      //   message: "$GLGSV,3,1,11,72,62,303,,73,59,028,,74,59,264,,71,54,180,*6" 
      // }
    });
}

componentWillUnmount() {
  RNNmeaLibrary.stop();
}

We recommend https://github.com/infusion/GPS.js for parsing NMEA sentances, and getting satellite info.

##Notice NMEA data is not available on emulators, you will have to use Android device for testing and development.
