React Native Bluetooth Classic Hex is basically to provide the Hexadecimal support for data communtication.
Based off the react-native-bluetooth-classic, and updated to support the Hexadecimal data communication.
const data = await RNBluetoothClassic.readFromDevice();
npm install buffer
const Buffer = require('buffer/').Buffer;
writeData = async (data) => {
const dataToWrite = new Buffer.from(data, 'hex');
await RNBluetoothClassic.write(dataToWrite);
};
