The toggle logic doesn't handle intermediate states. The bluetooth radio could be in states other than On or Off (such as Unknown or Disabled). If bluetoothRadio.State is not RadioState.On, the code will attempt to turn it On, which may not be the intended behavior for all states. Consider checking if the current state is valid before toggling.

Suggested change

	var newState = bluetoothRadio.State == RadioState.On ? RadioState.Off : RadioState.On;
	var currentState = bluetoothRadio.State;
	if (currentState != RadioState.On && currentState != RadioState.Off)
	{
	Console.WriteLine($"Bluetooth cannot be toggled from the current state: {currentState}.");
	return;
	}
	var newState = currentState == RadioState.On ? RadioState.Off : RadioState.On;
