IBleManager.IsScanning is always False in Apple

[Patrick Long]

Component/Nuget

BluetoothLE Client (Shiny.BluetoothLE)

What operating system(s) are effected?

• iOS (13+ supported)
• Mac Catalyst
• Android (8+ supported)
• Windows (.NET 7 Target - only Core is currently supported, BLE is coming)

Version(s) of Operation Systems

Tested on iOS 17.1.1

Hosting Model

• MAUI
• Native/Classic Xamarin
• Manual

Steps To Reproduce

Call Scan on the IBleManager. In the Subscribe action simply write out this.shinyBleManager.IsScanning to debug.

Expected Behavior

IsScanning would be True.

Actual Behavior

IsScanning is false. Looking at the implementation of BleManager for Apple I can see that IsScanning is never set to True whereas it is on Android.

Exception or Log output

No response

Code Sample

if (!this.IsScanning)
{
    try
    {
        this.scan = this.shinyBleManager
                        .Scan(scanConfig)
                        .Buffer(TimeSpan.FromSeconds(1))
                        .Subscribe(
                                    results =>
                                              {
                                                  System.Diagnostics.Debug.WriteLine("IsScanning: "  + this.shinyBleManager.IsScanning);
                                                  
                                                  // Only raise events if there's items to return
                                                  if (results.Any())
                                                  {
                                                      this.ScanResultUpdated?.Invoke(this, results.Select(x => new ScanResultWrapper(x)));
                                                  }
                                              }, 
                                    errorAction);
    }
    catch (Exception ex) 
    {
        System.Diagnostics.Debug.WriteLine("InternalStartScan Exception " + ex.Message);
    }
