Tesla does over the air updates: they can do it because the car is always connected (either via WiFi or cellular).



I don't think this device will be networked (because cost).



However, it makes sense that it would be software-updatable (it's just the norm for micro controllers), but I wouldn't be surprised if the procedure to update it required either a special hardware dongle and/or special software that is not available to the general public.



This is extremely common for all medical devices (they don't let people hack their devices).

I imagine you'd have to bring the device to a professional to upgrade it, perhaps for a fee.
