React Native Bluetooth Low Energy library using RxBluetoothKit and RxAndroidBle as it's backend libraries.
Example apps are available in Google Play and App Store!
What this library 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
- bonding peripherals
0.9.0
Breaking changes:
- Use
error.errorCode == BleErrorCode.OperationCancelled
instead oferror.message == 'Cancelled'
- Use
error.errorCode == BleErrorCode.BluetoothManagerDestroyed
instead oferror.message == 'Destroyed'
- Reverted implementation of
monitorCharacteristicForDevice
to properly write to descriptor when last listener is unsubscribed on Android. If you expect to get new notifications as soon as you subscribe for them please use version0.8
for the time being, as regression is expected.
Other:
- All API calls return
BleError
instance in case of errors which contains additional fields:errorCode
- returns API independent and stable error code (defined inBleErrorCode
).attErrorCode
(optional) - platform independent ATT error code.iosErrorCode
(optional) - iOS specific error code.androidErrorCode
(optional) - Android specific error code.reason
(optional) - platform specific message.
- Updated
BleModuleInterface
type to fix flow errors related to usage. - Added
refreshGatt
option toconnectToDevice
function. - Parse short
localName
advertisement data type on Android. - Don't emit state changes when BLE is not supported.
- Added
devices
andconnectedDevices
functions. - Fixed iOS issue related to
requiresMainQueueSetup
. - Added
timeout
option toconnectToDevice
.

If you do not have Carthage (ver. 0.21+) installed yet and wish to set up for iOS, please install it first and only then follow the steps given below
npm install --save react-native-ble-plx
react-native link react-native-ble-plx
Both on iOS and Android continue manually from step 7.
- Add
react-native-ble-plx
to a project as a dependency inpackage.json
file. For example"react-native-ble-plx": "Polidea/react-native-ble-plx"
will install latest version from Polidea's Github repository. - Make sure that you have Carthage installed on your system.
- Execute
npm install
to fetch and install a library. - Open iOS project located in
./ios
folder. - Move
BleClient.xcodeproj
located in.node_modules/react-native-ble-plx/ios
using drag & drop toLibraries
folder in your project. - In general settings of a target add
libBleClient.a
to Linked Frameworks and Libraries. - In
Build Settings
/Search Paths
/Framework search paths
add path:$(SRCROOT)/../node_modules/react-native-ble-plx/ios/BleClientManager/Carthage/Build/iOS
. - In
Build Settings
/Build Options
/Always Embed Swift Standard Libraries
set toYes
. - In
Build Phases
click on top left button and addNew Run Script Phase
.
- Shell command:
/usr/local/bin/carthage copy-frameworks
- Input Files:
$(SRCROOT)/../node_modules/react-native-ble-plx/ios/BleClientManager/Carthage/Build/iOS/BleClientManager.framework
$(SRCROOT)/../node_modules/react-native-ble-plx/ios/BleClientManager/Carthage/Build/iOS/RxSwift.framework
$(SRCROOT)/../node_modules/react-native-ble-plx/ios/BleClientManager/Carthage/Build/iOS/RxBluetoothKit.framework
- Minimal supported version of iOS is 8.0
- If you want to support background mode:
- In your application target go to
Capabilities
tab and enableUses Bluetooth LE Accessories
inBackground Modes
section. - Pass
restoreStateIdentifier
andrestoreStateFunction
toBleManager
constructor.
- In your application target go to
- Add
react-native-ble-plx
to a project as a dependency inpackage.json
file. For example"react-native-ble-plx": "Polidea/react-native-ble-plx"
will install latest version from Polidea's Github repository. - 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
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
build.gradle
ofapp
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
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"
...
Currently [02.02.2018] to use this library with Expo one must first detach (eject) the project and follow the above instructions. Additionally on iOS there is a must to add a Header Search Path
to other dependencies which are managed using Pods
. To do so one has to add $(SRCROOT)/../../../ios/Pods/Headers/Public/**
to Header Search Path
in BleClient
module using XCode
. This can be further automated by a git apply patch
executed as a postinstall
script defined in package.json
.
Add this to your app/proguard-rules.pro
-dontwarn com.polidea.reactnativeble.**
