[sebastianhoeck]

Version

1.1.0

Platform

iOS

OS version

iOS 13

General versions

1. react-native: 068.0
2. react: 17.0.2
3. beacon library: 1.1.0
4. pod. 1.11.3
5. npm: 9.2.0
6. node: 18.1.0

Steps to reproduce

1. react-native init myTestApp --version=0.68.0
2. Add library version 1.1.0 ("react-native-beacons-manager": "git://github.com/MacKentoch/react-native-beacons-manager.git#53c1bda")
3. cd ios && pod install
4. add minimal example

import React from 'react';

import {Text, View} from 'react-native';

import {Beacons} from 'react-native-beacons-manager';

const App = ({route, navigation}) => {
    Beacons.requestAlwaysAuthorization();
    Beacons.allowsBackgroundLocationUpdates(true);

    return (
        <View>
          <Text style={{color: 'white', top: 150}}>test</Text>
        </View>
    );
};

export default App;

Expected behavior

The app should be started successfully

Actual behavior

I get the following errors:

Error: Requiring module "node_modules/react-native-beacons-manager/index.js", which threw an exception: Invariant Violation: `new NativeEventEmitter()` requires a non-null argument. 

TypeError: undefined is not an object (evaluating '_$$_REQUIRE(_dependencyMap[2], "react-native-beacons-manager").Beacons')

I have used the library several times in my projects. But now I get the mentioned error and don't know why. I have even created a minimal example. This is described above. But still I have the error. Does anyone know why?

Beacons is default export. Try
import Beacons from 'react-native-beacons-manager';
instead of
import {Beacons} from 'react-native-beacons-manager';

Hi @iSaBo96 ,

Are you able to make it work?

[sebastianhoeck]

@gigflex yes, what is your problem with this?

Hi @iSaBo96

we are able to run the code somehow but getting the following error

[CoreBluetooth] XPC connection invalid

beaconsDidRange never fires

[sebastianhoeck]

Have you linked the library?

You must link the library in XCode under "Libraries".
You have to link the binary "RNiBeacon.a" in you project phases

[sebastianhoeck]

which version do you use?

[sangheraajit]

@iSaBo96
We are using
git+https://github.com/MacKentoch/react-native-beacons-manager.git

and ios 13
We are unable to find RNiBeacon.a

[sangheraajit]

Hi @iSaBo96 ,

We are able to see
Beacons ranging started succesfully
and
Beacons monitoring started succesfully

log
but beaconsDidRange event never fires

[sebastianhoeck]

You have to add RNiBeacon.a

I also use "react-native-beacons-manager": "git+https://github.com/MacKentoch/react-native-beacons-manager.git", in my package.json file.

Please follow the path in the screenshot to add the RNiBeacon.a. If you do not found it, do a "pod install" in your ios folder

[sebastianhoeck]

And you have to link the library manually

And you have to the the following path in the linked library. Go there to "build settings" and add the following:

In your App you have to add the following under "Build settings" > "Header Search Paths"

Hi @iSaBo96

Do you have a working copy if you can share that will be a great help.
Thanks

[sebastianhoeck]

Please tell me which react-native version you are using. I Use 0.70.6.
I have a working copy, but i cannot share this, because it is a production code.

From which country you are? Maybe i can offer you a call tomorrow?
I come from germany and the current time is 18:45
