react-native-ble-plx – React Native Bluetooth Low Energy (BLE) library

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

scanAndConnect() {
    this.manager = new BleManager();

    // Wait for PoweredOn state

    this.manager.startDeviceScan(null, null, (error, device) => {
        if (error) {

        // Check if it is a device you are looking for based on advertisement data
        // or other criteria.
        if ( === 'TI BLE Sensor Tag' || 
   === 'SensorTag') {
            // Stop scanning as it's not necessary if you are scanning for one device.

            // Proceed with connection.
                .then((device) => {
                    return device.discoverAllServicesAndCharacteristics()
                .then((device) => {
                   // Do work on device with services and characteristics
                .catch((error) => {
                    // Handle errors

Damnit, now I want to take on a new React Native project where I can use this library 😅
