React-native-ble-plx: Help - How to return CBCentralManager to use in react-native-nordic-dfu

[devgeno]

In react-native-nordic-dfu, there is a step to get CBCentalManager.

Call [RNNordicDfu setCentralManagerGetter:<...>] with a block argument that returns
your CBCentralManager instance (see example project for how this may be done).
It is assumed that you have initiated this instance outside of this library, for flexibility.

the AppDelegate.m in the example (react-native-ble-manager)

 ...
#import "RNNordicDfu.h"
#import "BleManager.h"
...
[RNNordicDfu setCentralManagerGetter:^() {
return [BleManager getCentralManager];
}];
// Reset manager delegate since the Nordic DFU lib "steals" control over it
[RNNordicDfu setOnDFUComplete:^() {
NSLog(@"onDFUComplete");
CBCentralManager * manager = [BleManager getCentralManager];
manager.delegate = [BleManager getInstance];
}];
[RNNordicDfu setOnDFUError:^() {
NSLog(@"onDFUError");
CBCentralManager * manager = [BleManager getCentralManager];
manager.delegate = [BleManager getInstance];
}];   
...

What I've tried (sadly, not work)

...
#import "RNNordicDfu.h"
@import BleClientManager;
...
[RNNordicDfu setCentralManagerGetter:^() {
return [BleClientManager init];
}];
...

I need to make dfu work with ble-plx.
Does anybody know, how can I solve this?
My deps is

"dependencies": {
"immutable": "^3.8.2",
"native-base": "^2.3.10",
"react": "16.2.0",
"react-native": "0.52.1",
"react-native-ble-plx": "^0.9.0",
"react-native-fs": "^2.9.12",
"react-native-nordic-dfu": "^1.1.2",

"react-native-timer": "^1.3.1",
"react-native-vector-icons": "^4.5.0",
"react-navigation": "^1.4.0"
},

Thank you for your help in advance.

I've succeed updating firmware on android using ble-plx with nordic-dfu. However, stucked in iOS

I was trying to use the react-native-nordic-dfu and had success just by using:

    [RNNordicDfu setCentralManagerGetter:^() {
        return [[CBCentralManager alloc] initWithDelegate:nil queue:dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0)];
    }];

    // Reset manager delegate since the Nordic DFU lib "steals" control over it
    [RNNordicDfu setOnDFUComplete:^() {
        NSLog(@"onDFUComplete");
    }];
    [RNNordicDfu setOnDFUError:^() {
        NSLog(@"onDFUError");
    }];

And nothing more

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.

For reference, I've tried this. Even after connecting/scanning I still get that the the device id can not be found:

[Error: Could not find device with deviceAddress]

I've resorted to using the https://github.com/innoveit/react-native-ble-manager library which does work. But this is of course less than ideal.

Android did work with the DFU library without any issues.
