But, I just kept optimizing and whittling it down and eventually ended up back with the original circuit. This badge is the same one I showed off six months ago. It’s unmodified there are no hardware changes at all. So in a sense, the ability to do wireless updates was there all along – we just had to unlock it, by thinking really hard about the problem.</text></comment>
