Cross-Platform Bluetooth LE #
Posix SDK aims to offer the most from both platforms (iOS and Android).
Using the Posix SDK instance, you can scan for and check LED to nearby devices (BluetoothDevice).

Getting Started #
Change the minSdkVersion for Android #
Flutter_blue is compatible only from version 19 of Android SDK so you should change this in android/app/build.gradle:
Android {
defaultConfig {
minSdkVersion: 19

Add permissions for Bluetooth #
We need to add the permission to use Bluetooth and access location:
Android
In the android/app/src/main/AndroidManifest.xml let’s add:
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<application

IOS
In the ios/Runner/Info.plist let’s add:
<dict>
<key>NSBluetoothAlwaysUsageDescription</key>
<string>Need BLE permission</string>
<key>NSBluetoothPeripheralUsageDescription</key>
<string>Need BLE permission</string>
<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>Need Location permission</string>
<key>NSLocationAlwaysUsageDescription</key>
