Thank you for your answer.
The thread does not exactly match our case. It concerns not receiving any
Bluetooth events at all. In our case, we do receive the ActionFound event but
not ActionDiscoveryStarted or ActionDiscoveryFinished.
This is what we do:
Register:
IntentFilter filter = new IntentFilter();
filter.AddAction(BluetoothAdapter.ActionDiscoveryStarted);
filter.AddAction(BluetoothAdapter.ActionDiscoveryFinished);
filter.AddAction(BluetoothDevice.ActionFound);
RegisterReceiver(moReceiver, filter);
Receiver:
private class DiscoveryReceiver : BroadcastReceiver
{
private String msDeviceName = String.Empty;
public event BluetoothDeviceFound DeviceFound;
public override void OnReceive(Context context, Intent intent)
{
String action = intent.Action;
// When discovery finds a device
if (action == BluetoothDevice.ActionFound)
{
// called several times
// Get the BluetoothDevice object from the Intent
BluetoothDevice device =
intent.GetParcelableExtra(BluetoothDevice.ExtraDevice) as BluetoothDevice;
if (device.Name.ToLower().Contains(msDeviceName.ToLower()))
{
if (DeviceFound != null)
{
DeviceFound(device);
}
BluetoothAdapter.DefaultAdapter.CancelDiscovery();
}
}
else if (action == BluetoothAdapter.ActionDiscoveryStarted)
{
// never called
}
else if (action == BluetoothAdapter.ActionDiscoveryFinished)
{
// never called
}
}
}
Any idea what might be wrong here?

I would guess that you're hitting:
