[Help]: In startScan(withRemoteIds), I have a question about the behavior of with RemoteIds.

Requirements

• [X] I've looked at the README 'Common Problems' section

Have you checked this problem on the example app?

Yes

FlutterBluePlus Version

1.32.2

Flutter Version

What OS?

Android

OS Version

Android 14

Bluetooth Module

Nordic NRF52832

What is your problem?

I save 4 remoteIds in a variable called SavedAdd, and when scanning, I try to connect when the corresponding device is identified. However, the device was discovered only when the device corresponding to SavedAdds[0] was found, and the rest, including SavedAdds[1], could not be found.

This is my code.

List<String> SavedAdds = ['C3:A5:61:DD:F1:9F', 'EB:60:4C:9E:3F:10', 'None' , 'D4:CF:1A:6F:26:7D']

...

await FlutterBluePlus.startScan(
          withRemoteIds: [SavedAdds]
      );

Here I tried to connect a device with remoteID EB:60:4C:9E:3F:10, but the App couldn't find the device.

I'm not sure the cause. Try to debug it further.

btw, you can connect without scanning.

1. create BluetoothDevice with remoteId
2. await device.connect()

the code looks correct to me. probably just a coincidence. and your devices are having problems.

                        // remoteIds
                        for (int i = 0; i < withRemoteIds.size(); i++) {
                            String address = withRemoteIds.get(i);
                            ScanFilter f = new ScanFilter.Builder().setDeviceAddress(address).build();
                            filters.add(f);
                        }
