BluetoothLE - Device Names

[wagenheimer]

Using the command
var devices = await Bluetooth.ScanForDevicesAsync(); It founds this device :

Device ID "40D84FE277B" - Device Name = "BLE-TX R2 P3 F78 S02020"

But if I use

scan = await Bluetooth.RequestLEScanAsync(new BluetoothLEScanOptions { KeepRepeatedDevices = false, AcceptAllAdvertisements = false });

private void Bluetooth_AdvertisementReceived(object sender, BluetoothAdvertisingEvent e)
{
                Debug.WriteLine($"{e.Device.Name}");
}

Sometimes it found my device with the full name "BLE-TX R2 P3 F78 S02020", but other times it only shows "Plat. Celmi".

Using ScanForDevicesAsync I always have the correct name, but it needs to wait for the search to end. I would like to use RequestLEScanAsync because it does not need to wait for the search to end.

The name returned in an advertisement can be a shortened name rather than the full device name. The Windows device scan does a name lookup behind the scenes and populates the full device name. I'm looking at adding more control over the ScanForDevices method so that you can break out of it with a cancellation token or a shorter defined timeout.

@peterfoot is it possible to cancel RequestLEScanAsync?
