Try this:
componentDidMount() {
this.handleDiscoverPeripheral = this.handleDiscoverPeripheral.bind(this);
NativeAppEventEmitter.addListener(
'BleManagerDiscoverPeripheral',
this.handleDiscoverPeripheral
);
}
btnPress() {
BleManager.scan([], 5);
}
handleDiscoverPeripheral(data){
console.log(data);
}

That example would be awesome for documentation example
from react-native-ble-manager.
Hi, you have to scan for the peripherals and then use the id of the peripheral to connect.
from react-native-ble-manager.
So first I would call BleManage.scan()
and then connect
right? So will the scan()
method return a list of UUID or MAC addresses of active bluetooth devices?
from react-native-ble-manager.
First you have to handle BleManagerDiscoverPeripheral event, then start the scan and you receive the peripheral finded.

Hi Marco, I tried that. Does this code look right?
class bluetooth extends Component {
render() {
return (
<View style = { styles.container } >
<TouchableHighlight onPress = { this.btnPress }>
<Text>Bluetooth test</Text>
</TouchableHighlight>
</View>
);
}
btnPress() {
console.log(typeof BleManager === 'undefined');
console.log(DeviceEventEmitter.addListener());
DeviceEventEmitter.addListener('BleManagerDiscoverPeripheral', (args) => {
console.log(args)
BleManager.scan(args.id, 5)
.then(() => {
console.log('here');
})
});
}
}
The code for console.log(args)
does not seem to be called at all.
