[HausBJB]

Component/Nuget

BluetoothLE Client (Shiny.BluetoothLE)

What operating system(s) are effected?

• [X] iOS (13+ supported)
• [ ] Mac Catalyst
• [ ] Android (8+ supported)

Version(s) of Operation Systems

iOS-Version 16.6 Unfortunately, I was unable to test Android and other platforms

Hosting Model

• [X] MAUI
• [ ] Native/Classic Xamarin
• [ ] Manual

Steps To Reproduce

1. Start sample project
2. make sure there are at least two devices nearby that you can connect to
3. press the Click me button in the app
4. take a look at the console logs

Expected Behavior

I expect the connection to be disconnected after calling CancelConnection()

Actual Behavior

At the moment, if two devices are connected and then you disconnect from both devices, it will automatically reconnect a short time later and then it repeats itself over and over again, disconnecting and reconnecting, look at the logs

I do absolutely nothing special here. This is entirely on the platform to figure out.

I have never seen anything remotely close to this in any of my projects. The only thing I can see is that you're not cancelling out of your scan wave in the most appropriate way.

public ConnectionState Status => this.Native.State switch
{
    CBPeripheralState.Connected => ConnectionState.Connected,
    CBPeripheralState.Connecting => ConnectionState.Connecting,
    CBPeripheralState.Disconnected => ConnectionState.Disconnected,
    CBPeripheralState.Disconnecting => ConnectionState.Disconnecting,
    _ => ConnectionState.Disconnected
};

public void CancelConnection()
{
    this.autoReconnectSub?.Dispose();
    this.manager.Manager.CancelPeripheralConnection(this.Native);
}

I'd suggest pulling down the code to see what might be happening. There isn't really anything for me to solve here.
