ConnectToDevice does not return

[alessandrofrancesconi]

Ble.net version 1.2.1 Android API 28

I have this piece of code. I prepare a cancellation token of 3000ms, then I start the connection to a known device in another thread. I've found that:

• if the device is reachable, ConnectToDevice() returns successfully
• if it is not, the function never returns even with the cancellation token!

this.connectToken = new CancellationTokenSource(3000);
this.connectionTask = Task.Run(async () =>
{
    try
    {
        var connection = await this.ble.ConnectToDevice(
                new Guid(d.Address),
                connectToken.Token
        );
        
        if (connection.IsSuccessful()) // <--- not reaching this!
        {

I see that after 3 seconds this line appears: 06-09 21:55:02.130 D/BluetoothGatt(19579): cancelOpen() - device: 00:13:AA:00:7F:91

But nothing else and the code keeps stuck at ConnectToDevice()

I'm having the same problem. It seems to be working on iOS, but not on Android. Have you managed to get it working?
