This is React Native Bluetooth Low Energy library using RxBluetoothKit and RxAndroidBle under the hood.

It supports:

• observing device's Bluetooth adapter state
• scanning BLE devices
• making connections to peripherals
• discovering services/characteristics
• reading/writing characteristics
• observing characteristic notifications/indications
• reading RSSI
• negotiating MTU

What this library does NOT support:

• turning the device's Bluetooth adapter on
• communicating between phones using BLE (Peripheral support)
• bonding peripherals

0.10.0

Breaking changes:

• Deprecate old build system. Carthage is not required anymore. To fix your current project please do following steps:

  1. Add empty Swift file if you don't have at least one:
     • Select File/New/File...
     • Choose Swift file and click Next.
     • Name it however you want, select your targets and create it.
     • Accept to create Objective-C bridging header.
  2. Remove copy-frameworks script if you don't have any other dependency requiring it:
     • Go to Your Target / Build Phases
     • Remove run script.

Other:

• Fix warning when no listeners were attached and events were emitted.
• Show error.message properly. Make sure that invalid errorCodes from implementation side won't trigger another error during construction.
• Property ServiceUUID is properly propagated to IncludedServicesDiscoveryFailed's error message.
• Add missing deviceServicesNotDiscovered implementation on Android.

5. Update your ios/Podfile to contain:

   pod 'react-native-ble-plx', :path => '../node_modules/react-native-ble-plx'
   pod 'react-native-ble-plx-swift', :path => '../node_modules/react-native-ble-plx'

1. npm install --save react-native-ble-plx
2. react-native link react-native-ble-plx
3. In build.gradle of app module make sure that min SDK version is at least 18:

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

4. 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"
        ...

Add this to your app/proguard-rules.pro
