Tesla does over the air updates: they can do it because the car is always connected (either via WiFi or cellular).I've been thinking about this. If improvements can be made to the device by updating the firmware/software, they should be able to push out improvements to the treatment after it's in the hands of the user, à la Tesla, no?
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.
