For **BLE** to function correctly, the app must request location permissions from the user. This enables the app to determine if the device is within Bluetooth range.

###

```async function requestLocationPermission() {
  try {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
      {
        title: "Location Access Required",
        message: "This app needs to access your location to detect Bluetooth devices",
      }
    );
    if (granted === PermissionsAndroid.RESULTS.GRANTED) {
      console.log("Location permission granted");
    } else {
      console.log("Location permission denied");
    }
  } catch (err) {
    console.warn(err);
  }
} 
```

### How It Works: Message Brokers and Protocols
###
**Real-time functionality relies on two key components:**
###
**1. Message Brokers:** These act as intermediaries for transmitting data between clients and servers. Popular solutions include RabbitMQ, Kafka, Redis Pub/Sub, and more. For example, RabbitMQ supports WebSocket and MQTT, making integration with React seamless.
###
**2. Data Transfer Protocols:**
###
- **WebSocket:** Provides a bidirectional persistent connection, perfect for chats and gaming.
- **Server-Sent Events (SSE):** A one-way channel for sending updates from the server to the client.
- **gRPC Web:** A high-performance protocol ideal for streaming data.
###
### Where is Real-Time Used?
###
**Real-time technologies are applied in a wide range of fields:**
###
- **E-commerce:** Notifications about order status.
- **Gaming:** Interactive gaming interfaces.
- **Transportation:** Real-time tracking systems.
- **Finance:** Streaming market data.
- **Education and Business:** Video conferencing and collaborative platforms.
###
### Conclusions and Recommendations
###
**Real-time technologies unlock immense opportunities to enhance user experience. When selecting solutions, consider:**
###
- **Application Requirements:** For instance, WebSocket is suitable for bidirectional streams, while MQTT works well for IoT.
- **Scalability and Security:** Use message brokers and proxy servers to boost performance and safeguard data.
- **React Ecosystem:** Libraries such as socket.io or @stomp/stompjs simplify implementation.
