This plugin is not working for me. It does not recognise the class as it returns null
"
import SerialPortAPI from 'react-native-serial-port-api';
async function example() {
/* const devices = await SerialPortAPI.devicePathsAsync();
console.log(devices)*/
const serialPort = await SerialPortAPI.open("/dev/ttyS4", { baudRate: 38400 });
console.log(serialPort, 'serialPort');
// subscribe received data
const sub = serialPort.onReceived(buff => {
console.log(buff.toString('hex').toUpperCase());
})
// unsubscribe
// sub.remove();
// send data with hex format
await serialPort.send('00FF');
// close
serialPort.close();
}
example();

Which version?
juanstan commented
Hello,
I tried the version v.1.4.0-rc.1 as I saw it in previous messages. Previously I think I tried the latest version.
Thank you

I am not familiar with Expo. Can you try the latest version?
