How to read Data ?

[wysixontheflux]

I have to work on a native react application for work, but it's not exactly my field, I'm basically an engineer and not a developer, I try to follow the documentation but I'm having a little trouble.

This is my code :

import { Button } from "react-native";
import BleManager from "react-native-ble-manager";

const FetchData = () => {

const action = () => {
BleManager.start({showAlert : true}).then(() => {console.log('Blemanager Start')});

BleManager.connect('A0:6C:65:CF:7B:A7').then(() => {console.log('périphérique connecter')});

BleManager.retrieveServices('A0:6C:65:CF:7B:A7').then();

BleManager.read('A0:6C:65:CF:7B:A7', 'FFE0', 'FFE1').then((data) => {
  console.log(data)
})

BleManager.startNotification('A0:6C:65:CF:7B:A7', 'FFE0', 'FFE1').then((data) => {
  console.log(data)
})

}

return(
<Button title={"show"} onPress={action} />
)
}

export default FetchData

Start, connect, retrieveservices is functionnal but i can't read data from my arduino ( HM-10 bluetooth module )
When i log the data of read, it return me the mac adresse in hexa of my HM-10 module.
Someone can help me please ?
