Overview:

React Native Bluetooth Classic is a library designed to facilitate the use of Bluetooth Classic on iOS devices by utilizing the External Accessory framework. It is an extension of the react-native-bluetooth-serial port, with improvements and updates targeted specifically at replacing CoreBluetooth (BLE) on iOS. The library offers different versions tailored to specific React Native versions, with considerations for potential breaking changes.

Features:

• Bridge for iOS Bluetooth Classic: Connects React Native applications to Bluetooth Classic on iOS through the External Accessory framework.
• Compatibility: Versions available for different ranges of React Native versions, ensuring compatibility with various app setups.
• Auto Linking: Supports autolinking for React Native 0.60.0 and above, simplifying the installation process.
• Manual Installation: Provides steps for manual installation, helpful for contributions or troubleshooting autolinking issues.
• Android Autolinking: Automatic configuration for autolinking on Android post React Native 0.60.0 update.
• Adjustable Linking: Ability to override default autolinking configuration to customize implementations on Android.

Installation:

Getting started:
Install the library from NPM for React Native 0.60.0 and later versions, which support autolinking.

Manual Installation (iOS):

1. In Xcode, navigate to project navigator, right-click Libraries ➜ Add Files to [your project’s name].
