Could not find device with deviceAddress [3.2.1]

[marcopiraccini]

I am having this issue when I startDFU on iOS (on Android it works).
I already checked and the deviceAddress is the UUID of the device (at it should be).
Any idea?

[marcopiraccini]

I guess the error comes from here: https://github.com/Pilloxa/react-native-nordic-dfu/blob/master/ios/RNNordicDfu.m#L210

OK, this is probably a duplicate of: #121 (I am also using react-native-ble-plx )

[david-gettins]

To save people from having to follow various links and collate the information, here is the solution that works for me when using react-native-ble-plx...

1. Your AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  // ...

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

  [RNNordicDfu setOnDFUComplete:^() {
  }];

  [RNNordicDfu setOnDFUError:^() {
  }];

  // ...
}

2. Inside the react-native-nordic-dfu folder in node_modules - RNNordicDfu.m

At line 200 or underneath the line: CBCentralManager * centralManager = getCentralManager(); add this:

[NSThread sleepForTimeInterval: 2];

Now everything works as expected. Apologies for duplicating this information but it took me 15mins to bring various bits from other issue comments together, hopefully this saves someone that time.

Finally, here is the patch I generated to apply this on install using patch-package:

     if (!centralManager) {

OK, but there is a reason why this patch is not applied directly to the code?
I can prepare a PR

[p4bl1t0]

Yes, this should be a Pull Request or be added to the library

[david-gettins]

@marcopiraccini Did you get around to preparing the PR?

[Irenedan]

@marcopiraccini, I'm using the "react-native-ble-plx" too, but I don't know what parts are zip made of. Could you please put a zip file of yours here?

NordicDFU.startDFU({ deviceAddress: '94:54:93:17:63:75', deviceName: 'test', filePath: fs.CachesDirectoryPath + '/dry.zip' })

[p4bl1t0]

The zip file should be your firmware code compiled by Arduino or Platform.io with the upload_protocol in nrfutil
