• Execute npm install to fetch and install a library.
• Open Android project located in ./android folder.
• In settings.gradle add following lines:

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

• In build.gradle of app module add following dependency:

dependencies {
   ...
   compile project(':react-native-ble-plx')
   ...

• Additionaly make sure that min SDK version is at least 18:

android {
    ...
    defaultConfig {
        minSdkVersion 18
        ...

• In MainApplication.getPackages import and add BleModule package:

import com.polidea.reactnativeble.BlePackage;
...

public class MainApplication extends Application implements ReactApplication {
    ...

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
        new BlePackage()
      );
}

• In AndroidManifest.xml add Bluetooth permissions and update <uses-sdk/>:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <uses-permission-sdk-23 android:name="android.permission.ACCESS_COARSE_LOCATION"/>

    <!-- Add this line if your application always requires BLE. More info can be found on:
         https://developer.android.com/guide/topics/connectivity/bluetooth-le.html#permissions 
      -->
    <uses-feature android:name="android.hardware.bluetooth_le" android:required="true"/>

    <uses-sdk
        android:minSdkVersion="18"
        ...
