### Start BLE Advertising

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Starts the BLE advertising process. This should be called after adding services and characteristics. Includes promise-based handling for success and errors.

```javascript
BLEPeripheral.start()
  .then(res => {
       console.log(res)
  }).catch(error => {
       console.log(error)
  })
```

### Set BLE Device Name

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Sets the broadcast name for the BLE peripheral device before starting advertising.

```javascript
BLEPeripheral.setName('RNBLETEST')
```

--------------------------------

### Configure Android Project (Manual)

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Manually configures the Android project to include the react-native-ble-peripheral library by updating settings.gradle and build.gradle files.

```gradle
android/settings.gradle:
... 
include ':react-native-ble-peripheral'
project(':react-native-ble-peripheral').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-ble-peripheral/android')

android/app/build.gradle:
... 
dependencies {
    /* YOUR DEPENDENCIES HERE */
   compile project(':react-native-ble-peripheral') // <--- add this
}
```

### Import BLEPeripheral Module

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Imports the BLEPeripheral module from the 'react-native-ble-peripheral' library in JavaScript.

```javascript
import BLEPeripheral from 'react-native-ble-peripheral'
```

--------------------------------

### Register Native Module (Java)

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Registers the RNBLEPackage native module in the MainActivity.java file for Android.

```java
import com.himelbrand.forwardcalls.RNForwardCallsPackage;  // <--- import

public class MainActivity extends ReactActivity {
  ......

  @Override
  protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
          new MainReactPackage(),
          new RNBLEPackage() // <--- Add this
      );
  }

  ......

}
```

--------------------------------

### Add Android Bluetooth Permissions

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Adds necessary Bluetooth permissions to the AndroidManifest.xml file for BLE functionality.

```xml
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
```

--------------------------------

### Add BLE Service

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Adds a BLE service to the peripheral. Services are identified by UUIDs and can be primary or secondary.

```javascript
BLEPeripheral.addService('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', true) //for primary service
BLEPeripheral.addService('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', false) //for non primary service
```

--------------------------------

### Add BLE Characteristic

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Adds a characteristic to a specified BLE service. Requires service UUID, characteristic UUID, permissions, and properties.

```javascript
BLEPeripheral.addCharacteristicToService('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', 16 | 1, 8) //this is a Characteristic with read and write permissions and notify property
```

--------------------------------

### Stop BLE Advertising

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Stops the BLE advertising process.

```javascript
BLEPeripheral.stop()
```

--------------------------------

### Send BLE Notification

Source: https://github.com/himelbrand/react-native-ble-peripheral/blob/master/README.md

Sends a notification to all connected devices for a specific characteristic. The data should be an array of numbers representing bytes.

```javascript
BLEPeripheral.sendNotificationToDevices('XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX', [0x10,0x01,0xA1,0x80]) //sends a notification to all connected devices that, using the char uuid given
```
