Describe the bug Unhandled Exception: PlatformException(CBATTErrorDomain:10, The attribute could not be found., {NSLocalizedDescription: The attribute could not be found.},

To Reproduce Steps to reproduce the behavior:

1. scanForDevices -> OK
2. connectToDevice -> OK
3. discoverAllServices -> OK
4. characteristic.subscribe -> error

Smartphone / tablet

• Device: Iphone 13 Pro max
• OS: 16.3.1
• Package version: 5.2.0
• flutterSdkVersion: "3.7.3"

Android still works fine, I see there is a difference between android and ios regarding UUID

• Android

• IOS

[Taym95]

Android publishes as Service UUID as long ID, iOS publishes as Service UUID as short ID, try this for example:

  static const _shortUuid = "ffff";
  static const _extendedUuid = "0000ffff-0000-9999-9999-0099999999";
  static final Uuid uuid = Platform.isAndroid ? Uuid.parse(_extendedUuid) : Uuid.parse(_shortUuid);
