Receiving messages from bluetooth device

[ramacha7]

I wanted to know how I could receive a message from a Bluetooth device. Currently I am using a Bluetooth module that can be used to communicate between a microcontroller and an App I have created. I wanted to test sending a message from the microcontroller to the app. I was wondering how I could receive the message? I have seen in the RCTBluetoothSerialModule.java file you can read with events like BluetoothSerial.on("read"). I was wondering if there were any examples I could use to figure out how to actually implement reading data from a device

If 'msg' is your state that is going to hold received data, then add these lines in your UNSAFE_componentWillMount() -

BluetoothSerial.withDelimiter('\n').then(() => {
Promise.all([
BluetoothSerial.isEnabled(),
BluetoothSerial.list(),
]).then(values => {
const [isEnabled, devices] = values;
this.setState({ devices });
});
BluetoothSerial.on('read', data => {
this.setState({msg: data.data})
});
});

Make sure you use correct delimiter while sending data from microcontroller.
