react-native-aws-freertos

React native aws freertos bridge

Installation

npm install react-native-aws-freertos
cd ios && pod install

Open the ios project with xcode and run from there to a physical device, since npx react-native-run ios will open in the simulator and it wont connect to any bt device.

Android Add this to your manifest file under android/app/src/main/AndroidManifest.xml

    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <!-- initiate device discovery and manipulate bluetooth settings -->
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <!-- allow scan BLE -->
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

IOS Add this to your Podfile

  use_frameworks! :linkage => :static
  pod 'AmazonFreeRTOS'
  pod 'AWSAuthUI'
  pod 'AWSMobileClient','~> 2.17.0'
  pod 'AWSUserPoolsSignIn'
  pod 'react-native-aws-freertos', :path => '../node_modules/react-native-aws-freertos'

Make sure you add bt permissions keys to your Info.plist

<key>NSBluetoothPeripheralUsageDescription</key>
<string>The app needs access to Bluetooth</string>
<key>NSBluetoothAlwaysUsageDescription</key>
<string>We need to acces BLE to update the device</string>

Usage

import AwsFreertos from "react-native-aws-freertos";

// ...
AwsFreertos.getConnectedDeviceAvailableNetworks(deviceMacAddress);
const eventEmitter = new NativeEventEmitter(NativeModules.AwsFreertos);

const wifiListEvent = eventEmitter.addListener(
    eventKeys.DID_LIST_NETWORK,
    (network: WifiInfo) => {
      console.log(network)
    }
);
